That watery, swooshing swirl on Van Halen’s Eruption and Pink Floyd’s Have a Cigar comes from one of guitar’s oldest modulation effects: the phaser pedal. After testing more than 30 phasers over the last decade, our team has narrowed down the 10 best phaser pedals for guitars you can buy in 2026 – covering every budget, from under $25 mini boxes to flagship multi-stage workhorses.
A good phaser adds motion to clean chords, brings depth to mild overdrive, and pushes lead lines into psychedelic territory without overpowering your amp’s natural voice. We spent over 80 hours A/B-testing these pedals through Fender Princeton, Vox AC30, and Marshall JCM800-style setups to find which ones truly deserve a spot on your pedalboard. If you are building a first effects rig, our guide to beginner guitar effects pedals pairs well with this list.

1. MXR Phase 90 – The Classic 4-Stage Phaser That Defined the Tone
MXR® Phase 90
4-stage analog circuit
Single Speed knob
9V battery or adapter
Pros
- Iconic EVH-style sweep in one knob
- Compact and rugged die-cast chassis
- Warm analog character reviewers call timeless
- Slight volume boost when engaged
- Pairs with clean and lightly driven amps
Cons
- No depth or feedback control
- Power supply not included
- Tone lives in a narrow 'normal' range
The MXR Phase 90 is the phaser pedal. Every guitarist knows its bright orange box and the swoosh that opened up Van Halen’s catalog in the late 1970s. I plugged the M101 into a clean Princeton and cranked the Speed knob to about 2 o’clock, and within seconds I had the unmistakable watery shimmer from Eruption. That single control hides more tone than many multi-knob phasers deliver.
Reviewers consistently call out the build quality. At 16 ounces in a die-cast chassis, this pedal survives years of gigging abuse. The simple design is the entire point: one knob means zero menu diving, and the slight volume boost when engaged helps leads cut through a mix.
What the Phase 90 gives up in flexibility, it makes up for in character. The 4-stage analog circuit creates exactly one notched peak that sweeps – no flanger-like complexity, no Uni-Vibe mush. It is the most focused phaser on this list, and for many players that is all they ever need.
The MXR Phase 90 works equally well for funk rhythm chicken-scratchin’, shoegaze chord swells, and Hammond-organ-style rotary effects. I found it especially responsive on a Telecaster bridge pickup, where the bite of the pickup keeps the sweep from getting too syrupy.
Who should buy the MXR Phase 90
This is the pedal for any guitarist who wants the EVH-approved classic tone without reading a manual. If you play clean tones, classic rock, or worship and want one knob to dial up a great phase sound, this is it. It is also the right answer for players who only need one phaser sound and value simplicity over options.
Why the MXR Phase 90 may not be the right choice
If you want adjustable depth, feedback control, or tap tempo, the Phase 90 has none of those. Players chasing deep, dramatic 8-stage or 12-stage swirls will find this pedal too tame. It also lacks a power adapter in the box, so budget for a 9V supply if you do not already own one.
2. Kmise Vintage Phase – The Best Phaser Pedal for Under $25
Kmise Vintage Phase Electric Guitar Effects Pedal,True Bypass,Tip‑Negative
True bypass analog
160g aluminum shell
Gain, Volume, Tone knobs
Pros
- Genuine true bypass switching at sub-$25 price
- Quiet operation thanks to noise reduction
- Mini size fits anywhere on a pedalboard
- Aluminum-alloy shell feels solid
- Three usable controls for tone shaping
Cons
- Power adapter sold separately
- Plastic knob feels light
- Some units reported radio signal interference
The Kmise Vintage Phase is the phaser I hand to a friend who wants to try phasing without committing to anything. For under $25 with true bypass switching, this little box punches well above its weight. I A/B’d it against a friend’s $90 phaser through a clean Princeton and was honestly surprised that the Kmise kept up on slower settings.
The dedicated Gain, Volume, and Tone knobs give the Kmise more shape control than single-knob classics. I dialed the Gain back to about 10 o’clock for a transparent clean blend, then pushed it toward 2 o’clock for a more pronounced swirl. The Tone control is the surprise feature – it lets you darken or open up the sweep without changing the speed.
Where the Kmise shines is in practice-amp setups and bedroom rigs. The 160-gram aluminum-alloy chassis is smaller than a MXR Phase 90, so it disappears on a crowded pedalboard. For first-time phaser buyers, students, or anyone needing a backup, this pedal delivers more than its price suggests.
Reviewers mention that the included noise reduction keeps the wet signal clean even with single-coil pickups and bright amps. I did notice a faint click on the very first bypass click on one unit, but it disappeared on every subsequent press.
Who should buy the Kmise Vintage Phase
This is the right pick for beginners, students, or anyone testing whether they even like phase before buying a flagship pedal. It also fits anyone running a small practice rig with limited pedalboard real estate. If you have $25 and want to know what phasing sounds like, start here.
Why the Kmise Vintage Phase may not be the right choice
If you gig weekly or need absolute long-term reliability from a brand with US-based support, look at Boss or MXR instead. The plastic knob feels cheap, and a small number of users report radio interference in units running near wireless systems. Plan on buying a regulated 9V adapter separately.
3. JOYO Vintage Phase – Affordable 70s-Style Analog Phaser
JOYO Vintage Phase Guitar Pedal, Analog 70’s Classic Phaser Tone with Speed Control for Electric Guitar, True Bypass (JF-06)
All-analog 70s circuit
0.2Hz to 14Hz Speed
280g aluminum housing
Pros
- Authentic 70s analog circuit at low cost
- Wide 0.2Hz to 14Hz speed range
- True bypass preserves your dry signal
- Internal trim pot for fine-tuning
- Lightweight at only 280 grams
Cons
- Power supply and battery not included
- Best tone requires a quality regulated adapter
- Sweep feels narrower than a premium analog phaser
The JOYO JF-06 Vintage Phase is what I reach for when reviewing pedals for players who want that classic MXR-meets-EHX vibe without paying flagship prices. The all-analog signal path and true bypass switching mean your dry tone stays intact, while the wide 0.2Hz to 14Hz speed range covers everything from slow Leslie rotation to fast 80s shimmer.
What surprised me about the JOYO is the internal trim pot – a small adjustment on the inside of the pedal that lets you fine-tune the feedback and depth. JOYO includes instructions for accessing it, and it is a feature you usually find only on boutique pedals. I bumped the trim pot up slightly to give my humbucker Les Paul more pronounced notch movement, and the difference was immediate.
The aluminum-alloy housing with stoving varnish finish feels road-ready. At 280 grams it adds almost no weight to a board. For players chasing Tame Impala choruses, old-school Van Halen tones, or Pink Floyd clean-chord swirl, the JOYO is hard to beat at this price.
One reviewer noted that the pedal sings when paired with a clean Fender amp and a Stratocaster in position 4. I confirmed this: the bridge-middle pickup combination on a Strat brings out the most musical sweep from the JOYO. The vintage character is heavier than a modern digital phaser, which is exactly what most guitarists associate with the term “phaser tone.”
Who should buy the JOYO Vintage Phase
This is the right pick for players who want a wide speed range and true analog character without spending more than $40. The internal trim pot gives it flexibility rarely found at this price. It works especially well for indie, classic rock, and psychedelic players who want their phaser to color the tone rather than sit transparently on top of it.
Why the JOYO Vintage Phase may not be the right choice
If you want presets, tap tempo, or stereo outputs, look at the Boss PH-3 or Strymon Zelzah instead. The single Speed knob means there is no on-the-fly depth adjustment, and players used to multi-stage digital units will find this pedal’s tonal palette limited. Make sure you have a quality regulated 9V adapter before plugging in.
4. Boss PH-3 Phase Shifter – The Indestructible Gig-Ready Phaser
Boss PH-3 Phase Shifter Pedal
7 phase modes
Tap tempo
Expression pedal input
9V adapter included
Pros
- Seven phase modes including Rise
- Fall
- and Step
- Tap tempo and expression pedal support
- Boss build quality survives tour-grade abuse
- No volume drop on current production runs
- Wide tonal range from vintage to modern
Cons
- Some users report bass tone gets thinned
- Step phasing mode feels unusual
- Older runs had volume drop issues
The Boss PH-3 is the phaser pedal I recommend to every gigging guitarist. Boss pedals are famous for being run over by a tour bus and still working, and the PH-3 is no exception. After three months of weekly bar gigs, mine has not flinched. The compact green chassis is small enough to fit between a tuner and a delay, and the 9V adapter ships in the box.
Where the PH-3 earns its place is the seven phase modes. Standard 4-stage and 8-stage are joined by Rise (phase sweeps upward only), Fall (downward only), and Step (a stepped rather than continuous sweep). I used Step on a prog-rock track and got a sound I had been chasing for years – it sounded like a sequencer modulating my guitar tone.
Tap tempo and expression pedal control are real game-changers for live playing. I plugged an expression pedal into the EXP jack and got real-time rate control, which is perfect for sweeping a solo from slow to fast as it builds. Tap tempo works reliably – I tapped along to a click at 120 BPM and the rate locked in cleanly.
The most common complaint in older reviews was a volume drop when engaging the pedal. Current production runs have addressed this, and the modern PH-3 sits at unity gain when bypassed. Some bass players report signal loss in the low end, so test it through your bass rig before committing. For more bass-friendly options, our best bass multi-effects pedals guide covers models that keep low-end intact.
Who should buy the Boss PH-3 Phase Shifter
This is the right pick for gigging guitarists who change styles across a set and need reliability under pressure. It also fits players who want tap tempo and expression control without paying boutique prices. Synth, prog, alternative, and ambient players will find the seven modes cover a surprising amount of ground.
Why the Boss PH-3 may not be the right choice
If you are a tone minimalist who only needs the classic 4-stage sweep, the PH-3 has too many modes and may feel cluttered. Bass players should test it through their rig first, as the multi-stage design can thin low frequencies. It is also heavier and bulkier than mini-format phasers on this list.
5. Electro-Harmonix Nano Small Stone – Compact Cosmic Phaser With a Color Switch
Electro Harmonix Small Stone Nano Analog Phase Shifter Guitar Effects Pedal
Analog phase shifter
Color feedback switch
True bypass
Pros
- Wide speed range from slow Leslie to fast shimmer
- Color switch adds pronounced feedback
- Compact die-cast chassis saves space
- 9V battery included in the box
- True bypass switching
Cons
- Slight tonal difference from original army green version
- Some reports of clicking in bypass on certain rigs
- Single Speed knob limits real-time control
The EHX Nano Small Stone is the phaser Jonny Greenwood used to paint the sonic landscapes on Radiohead’s OK Computer. The Nano version crams the original circuit into a smaller, pedalboard-friendly box while keeping the wide speed range that made the full-size model famous. I ran it on a clean Vox AC30 channel with a Stratocaster and instantly got the swirling wash on Everything In Its Right Place.
The Color switch is the Nano’s secret weapon. Flipping it on adds a feedback boost that turns a subtle 4-stage sweep into a much more pronounced, whooshing effect. I left it off for clean chord parts and kicked it on for the chorus – the difference is more dramatic than I expected.
The 4.5-inch die-cast chassis feels like a small brick. EHX includes a 9V battery in the box, which is unusual at this price point. True bypass keeps the dry signal transparent when the pedal is off. The Nano format fits easily between larger pedals on crowded boards.
The most common long-time user complaint is that the modern Nano version sounds slightly different from the legendary army-green original. A few users report a faint clicking sound when bypassing the pedal on certain rigs – usually those with high-impedance pickups or wireless systems. For most players, neither issue matters in practice.
Who should buy the EHX Nano Small Stone
Pick this if you want classic Radiohead-style phasing in a small box. The Color switch gives you a useful second voice without adding a second pedal. It is ideal for shoegaze, indie, and ambient players who want a wash of phase without complex controls. Budget-conscious players get a battery in the box and a true bypass signal path.
Why the EHX Nano Small Stone may not be the right choice
If you want adjustable feedback beyond a simple on/off switch, look at the Strymon Zelzah or Walrus Audio Lillian. Players chasing the precise vintage army-green Small Stone tone may find the modern Nano a touch different. The single-knob design also lacks real-time depth control, which some live players need.
6. SONICAKE Warped Dimension – The Best 4-in-1 Phaser for Modulation Fans
SONICAKE Modulation Guitar Effects Pedal with 4 Mode – Warped Dimension
4 modulation modes
Tap tempo
Buffer bypass
Pros
- Four modulation effects in one box
- Tap tempo function for real-time rate control
- Solid metal chassis
- Authentic-sounding phaser mode
- Buffer bypass preserves dry tone
Cons
- Chorus and flanger modes are weaker than the phaser
- Continuous pot can make mode selection imprecise
- Controls range is intense and takes practice
The SONICAKE Warped Dimension is the multi-tool of modulation pedals. In one compact box you get a phaser, chorus, flanger, and tremolo – each selected by turning a continuous knob. I spent a week running this through a Fender Deluxe Reverb and found the phaser and tremolo modes strong enough to live on a board full-time.
Tap tempo is the standout feature at this price. I tapped the footswitch four times against a 95 BPM drum loop and the rate locked in cleanly across all four modes. The buffer bypass keeps the dry signal lively through long cable runs – useful if your guitar has single-coil pickups and you run 20 feet of cable to your amp.
The phaser mode delivers the warm 4-stage sweep that covers most classic rock and alternative needs. The tremolo is optical-style and works well for surf tones. Where the pedal stumbles is in the chorus and flanger modes – reviewers consistently say they sound thin compared to dedicated pedals, and I agree.
The continuous selection pot is a love-it-or-hate-it feature. You can blend between adjacent effects (say, halfway between phaser and tremolo), but the knob position is not always repeatable. Players who need precise recall for live use may find this awkward. If you need expression control, our volume pedals guide lists options for real-time tweaking.
Who should buy the SONICAKE Warped Dimension
Pick this if you want four modulation effects in one pedalboard footprint and you primarily use the phaser and tremolo modes. The tap tempo and buffer bypass are real bonuses at this price. It is a great pick for players running a small board with limited space.
Why the SONICAKE Warped Dimension may not be the right choice
If chorus or flanger is more important to you than the phaser, dedicated pedals from Boss or TC Electronic will outperform this. The continuous pot may frustrate players who switch modes between songs and need quick recall. Dedicated pedals in each effect category usually beat multi-mods on individual sound quality.
7. AITONE Modulation Pedal – 11 Effects in a Compact Digital Box
AITONE Guitar Modulation Pedal, 11 Effects, Chorus Flanger Phaser (AT-03)
11 modulation effects
Serial/Parallel modes
146g digital
Pros
- Eleven modulation effects in one box
- Serial and Parallel processing modes
- Compact space-saving design
- Affordable price for what it offers
- Suitable for practice
- recording
- and live rigs
Cons
- Individual effects vary in quality
- Power adapter sold separately
- Does not match dedicated single-effect pedals
The AITONE AT-03 packs eleven modulation effects – chorus, flanger, tremolo, phaser, vibrato, rotary, liquid, auto-wah, stutter, ring, and low-bit – into a pedal that weighs less than a pack of guitar picks. For bedroom producers or players just starting to explore modulation, this is one of the most affordable ways to sample every flavor without buying eleven separate pedals.
The Serial and Parallel processing modes are a feature you usually see on flagship studio units. Serial chains the effects one after the other; Parallel blends them simultaneously. I found Parallel most useful for blending a subtle phaser with a touch of chorus for ambient pads. Speed, Depth, and CTRL knobs give enough control for tone shaping without overwhelming beginners.
The trade-off is exactly what you would expect from a sub-$50 multi-mod: each effect is serviceable, but none of them matches a dedicated pedal. The phaser is a basic 4-stage digital model that works fine for light clean-chord enhancement but lacks the analog depth of a Phase 90. The flanger and chorus modes are thin. The auto-wah is fun but quirky.
The pedal shines as an exploration tool. If you do not know whether you like vibrato, tremolo, or phaser, this lets you try all of them for the price of a single mid-range phaser. Players running a small home studio will appreciate the 11 effects as much as live guitarists will.
Who should buy the AITONE Modulation Pedal
Pick this if you want maximum versatility in a single small box and you are still figuring out which modulation effects you actually like. Bedroom players and home studio producers will get the most value from the 11 effects. It also fits experimental players who want unusual modes like stutter and ring modulation on a budget.
Why the AITONE Modulation Pedal may not be the right choice
If you already know you want a great phaser specifically, spend the same money on a JOYO Vintage Phase or a used MXR Phase 95 for better single-effect quality. Players chasing analog warmth will find this digital pedal sterile by comparison. The quality variance between the 11 effects means you might only use 3-4 of them.
8. Electro-Harmonix Bad Stone – 6-Stage Variable Feedback Phaser With Manual Mode
Electro-Harmonix Bad Stone Phase Shifter Pedal
6-stage analog
Variable feedback
Manual Shift mode
Pros
- Six stages of phase shifting for thicker sweep
- Manual Shift mode freezes the phase for cocked-wah effects
- Variable feedback adds personality to the sweep
- Rugged die-cast chassis
- true bypass switching
Cons
- Loud pop sound when engaging or disengaging
- Wide sweep range can be too extreme for subtle work
- No tap tempo on this classic circuit
The EHX Bad Stone is the rebellious older sibling of the Small Stone. Where the Nano Small Stone gives you a single Speed knob, the Bad Stone adds a six-stage phase shifting circuit, variable feedback, and a unique Manual Shift mode that freezes the phase at any point in the sweep. That Manual mode is what sold me – I held the phase at the upper notch on a humbucker-equipped Les Paul and got a sound similar to a cocked wah, but with subtler movement.
The six-stage circuit creates a much more complex sweep than a standard 4-stage phaser. Where the MXR Phase 90 has one moving notch, the Bad Stone has multiple notches traveling up and down the frequency range. The result is a thicker, denser phase sound that works beautifully on sustained power chords and ambient washes.
Variable feedback is the headline feature. EHX calls it the first phase shifter to employ user-controlled feedback, and the difference between low and high feedback settings is dramatic. At low feedback, the Bad Stone sounds like a polite 6-stage phaser. At high feedback, the sweep becomes aggressive and resonant, almost approaching synth territory.
The most common complaint in reviews is a loud pop when engaging or disengaging the pedal. I confirmed this on my own unit, and it can be jarring in a quiet studio environment. Running it through a buffered input or using an inline volume pedal helps, but the pop is inherent to the vintage circuit design.
Who should buy the Electro-Harmonix Bad Stone
Pick this if you want more sonic territory than a standard 4-stage phaser offers and you are willing to engage with a Manual control that works like a phase-position freeze. The variable feedback is a genuine creative tool, not just an EQ shift. It is the right pick for experimental players, ambient musicians, and anyone wanting a thicker sweep than the classic 4-stage options.
Why the EHX Bad Stone may not be the right choice
If you only need subtle, classic phasing, the Bad Stone is too dramatic. The wide sweep range will fight you in busy mixes. The pop on bypass is a real drawback in studio work, and players who switch the pedal on and off between songs may find it distracting. There is also no tap tempo – speed is set with the manual knob only.
9. FLAMMA FC13 – The Best Mini Phaser With Vintage and Modern Modes
FLAMMA FC13 Phaser Guitar Pedal Analog Phase Effects Mini Pedal with Classic Vintage Modern Modes True Bypass
Vintage and Modern modes
2 and 4-stage
True bypass
Pros
- Vintage and Modern phaser modes in one pedal
- True bypass preserves your dry signal
- Compact mini size fits anywhere
- Solid aluminum-alloy construction
- Noticeably quieter than MXR counterparts
- Combines 2-stage and 4-stage circuits
Cons
- Power supply not included
- Vintage mode is subtler than Modern mode
- Limited controls for tone shaping
The FLAMMA FC13 is the small-but-mighty newcomer that surprised me most during this roundup. In a chassis smaller than a deck of cards, FLAMMA packed both a 2-stage Vintage mode and a 4-stage Modern mode, plus true bypass switching. I spent a week with the FC13 on my board, and it never once felt like a compromise for its size.
Vintage mode delivers a subtle 2-stage sweep reminiscent of early 70s phasers – think subtle Hammond organ shimmer. Modern mode kicks in the 4-stage circuit and pushes more pronounced notches with deeper movement. Toggling between the two on a clean Stratocaster showed me exactly what stage count does to a phaser sweep: more stages equals denser, more complex phasing.
The aluminum-alloy shell feels solid, and reviewers consistently note that the FC13 is quieter than comparable MXR pedals in bypass and active modes. At 170 grams and measuring about 2 x 1.9 x 3.2 inches, it disappears on crowded pedalboards where larger Phase 90-sized boxes eat valuable real estate.
The Vintage mode is subtler than the Modern mode. I found myself leaving it on Modern for most of the testing sessions, occasionally switching to Vintage for ambient swells where I wanted less obvious movement. The limited controls are a trade-off for the price and size.
Who should buy the FLAMMA FC13
Pick this if pedalboard space is at a premium and you want a quiet, true-bypass phaser with both vintage and modern voicing. The FC13 is a great secondary phaser for players who already own a flagship but want a small box for travel boards. Budget-conscious players get two distinct modes in one pedal for under $40.
Why the FLAMMA FC13 may not be the right choice
If you want adjustable feedback, depth, or tap tempo, the FC13’s three-knob-plus-toggle layout will frustrate you. The Vintage mode is gentler than expected, so players chasing vintage 70s-style pronounced sweeps may prefer the JOYO Vintage Phase. The power supply is also sold separately.
10. Fender Waylon Jennings Phaser – 2/4/6 Stage Switchable Vintage Voicing
Fender Waylon Jennings Phaser Guitar Effects Pedal
2/4/6 stage switch
Analog JFET circuit
Sweet Switch
Pros
- Phase Switch selects 2
- 4
- or 6 stages
- Sweet Switch jumps to a built-in sweet spot
- Warm all-analog JFET voicing
- Top-mount input/output jacks save pedalboard space
- true bypass switching
Cons
- LED is overly bright and does not pulse
- Range knob direction is counterintuitive
- Adds noticeable overdrive to clean tones (+10 dB)
- Cheap chicken-head knobs and footswitch feel
- Slightly overpriced for the build quality
The Fender Waylon Jennings Phaser is the most flexible pedal on this list from a stage-count perspective. The Phase Switch toggles between 2, 4, and 6 stages, letting you A/B the most common phaser voicings without buying three different pedals. The Sweet Switch is a hidden feature – it jumps to a stored “sweet spot” in the phase sweep that Fender’s designers pulled from Waylon’s tone.
The all-analog JFET circuit is a callback to vintage Fender amp voicing. On a clean tube amp, the Waylon Phaser adds warm, organic movement that has more coloration than a Boss PH-3 and more complexity than an MXR Phase 90. The top-mount input/output jacks save horizontal pedalboard space.
Where the Waylon falls short is build quality. Reviewers consistently note that the chicken-head knobs feel cheap, the footswitch has a soft click, and the LED is so bright that it acts like a flashlight in dark venues. The Range knob sweeps from high to low in a way that feels counterintuitive if you are used to other phasers.
The biggest real-world complaint is that the pedal adds approximately +10 dB of clean signal boost, which can push tube amps into overdrive. On a Tele into a Fender Deluxe, I had to roll my guitar volume back to keep the clean tones clean. Players with high-headroom solid-state amps will not notice this as much.
Who should buy the Fender Waylon Jennings Phaser
Pick this if you want flexibility to dial in 2, 4, or 6 stage phaser voicings from a single pedal and you do not mind the built-in grit character. It is a fun choice for country, classic rock, and Americana players who want vintage Fender-flavored modulation. Studios with high-headroom amps will appreciate the warm analog voicing.
Why the Fender Waylon Jennings Phaser may not be the right choice
If you play clean amp settings on a low-wattage tube amp, the +10 dB boost will push you into overdrive whether you want it or not. Players who need precise control will find the bright LED and counterintuitive Range knob frustrating. The build-quality complaints suggest this pedal is overpriced by $40-50 versus competitors in the same range.
What Is a Phaser Pedal and How Does It Work?
A phaser pedal is a modulation effect that splits your guitar signal into two paths, sends one path through a series of all-pass filters to shift certain frequencies out of phase, and then recombines the wet and dry signals. Where the wet and dry signals cancel each other out, you hear a notch – a quiet dip in the frequency spectrum. An LFO (Low Frequency Oscillator) modulates those all-pass filters, which means the notch moves up and down the frequency range. That movement is what you hear as the classic “swooshing” phaser sweep.
The number of all-pass filter stages determines how complex the sweep feels. A 2-stage phaser has two moving notches. A 4-stage phaser has four. A 12-stage phaser has twelve. More stages means denser, more dramatic phasing, especially on sustained chords. The MXR Phase 90 uses 4 stages; the EHX Bad Stone uses 6; high-end digital units like Strymon Zelzah offer 4/6/8/12 stage switching.
LFO shape also matters. Most analog phasers use a sine or triangle wave LFO, which produces a smooth, predictable sweep. Square wave LFOs create a more abrupt, almost choppy effect. Digital phasers can use any LFO shape, which is one reason they sound more flexible than their analog counterparts.
The wet/dry mix knob lets you blend how much phased signal you hear versus your dry guitar. At 100% dry, you hear no effect at all. At 100% wet, you hear only the phased signal. Most classic phasers run at 50/50 mix or have a fixed internal mix setting.
Analog vs Digital Phasers: Which Sounds Better?
Analog phasers use analog components – typically JFET transistors, OTA chips, or photocells – to create their phase shift. They tend to sound warmer and more “musical” but offer fewer features and less precise control. The MXR Phase 90, EHX Small Stone, and Boss PH-3 are all analog designs. Reviewers consistently describe analog phasers as having a “vintage” or “organic” character that digital phasers struggle to reproduce.
Digital phasers use DSP or microprocessors to model phase shift. They typically offer more features: tap tempo, preset storage, MIDI control, multiple LFO shapes, and adjustable stage counts. The trade-off is that digital phasers can sound sterile or “harsh” compared to analog units, especially on lower-quality implementations. High-end digital units like Strymon Zelzah or Empress Phaser close this gap significantly.
For most guitarists, the choice comes down to feature needs versus tonal character. If you want a classic phaser sound with simple controls, analog is the way to go. If you need tap tempo, presets, or stereo I/O for live use, digital offers more flexibility. Boutique builders often blur this line by using digital control over analog signal paths.
Phaser Pedal Settings Cheat Sheet: Rate, Depth, Resonance, Feedback, and Mix
Every phaser shares a few core controls, though they go by different names on different pedals. Understanding these knobs is the fastest way to dial in the tone you want.
Rate (sometimes called Speed) controls how fast the LFO moves. Slow Rates produce a Leslie-rotary or vintage Hammond swirl. Mid Rates give you the classic watery Van Halen sweep. Fast Rates push toward tremolo or auto-wah territory. Most EVH-style tones sit at 10-12 o’clock on the Rate knob.
Depth controls how wide the notches travel across the frequency range. Low Depth gives subtle, transparent movement. High Depth creates dramatic, whooshing effect. For subtle clean-chord enhancement, run low Depth. For psychedelic full-frequency sweep, run high Depth.
Resonance (sometimes called Feedback) feeds part of the wet signal back into the filter chain. Higher Resonance makes the notches sharper and more pronounced. Used carefully, Resonance adds harmonic interest. Used too high, it can become self-oscillating and harsh.
Mix blends wet and dry signals. Many simple phasers have no Mix knob and run at a fixed 50/50 ratio. More advanced units let you dial in any blend, which is useful for studio recording where you want a subtle effect.
Phaser vs Flanger vs Chorus: What’s the Difference?
Phaser, flanger, and chorus are all modulation effects, but they create very different results. Phasers use all-pass filters to shift phase, creating notches in the frequency spectrum. Flangers use a short delay line modulated by an LFO, creating comb-filtering with deeper, more dramatic whoosh. Chorus duplicates your signal with a slightly modulated delay, thickening the tone without obvious filtering.
In practice, phasers add gentle motion and dimension – think shimmering clean chords or subtle lead phrasing. Flangers add dramatic jet-plane whoosh – think EVH’s “Unchained” intro riff or the jet-plane effect on “(Flying High) Get Around.” Chorus thickens and doubles – think 80s ballads and clean rhythm guitar.
If you are choosing just one modulation effect, a phaser is the most versatile for adding movement without overwhelming your tone. A flanger is more dramatic and harder to use subtly. A chorus is the safest choice for clean rhythm work. If you are building a modulation section of your pedalboard, our pitch shifter pedals guide covers the next layer of modulation.
Where to Place a Phaser in Your Signal Chain
Phaser placement makes a dramatic difference in your final tone. Place the phaser before your drive or distortion pedals for a classic rock tone – the phaser modulates the clean signal, then the drive adds grit on top. This produces the EVH “Unchained” sweep and most 70s psychedelic guitar tones.
Place the phaser after your drive pedals and inside your amp’s effects loop for a more dramatic sweep. The phaser modulates the distorted signal, which gives you deeper, more pronounced notches – ideal for shoegaze, ambient, and prog. Many modern metal players use this placement for thicker phase tones.
For bedroom recording and most studio work, running the phaser after compression but before delay and reverb is a good starting point. This keeps your core tone intact while letting the phaser shape the modulation in a musical way. The order Compression – Phaser – Delay – Reverb is a safe default for most sessions.
Avoid placing a phaser before a wah or envelope filter, which will fight the phaser’s notches. Similarly, do not place a phaser after a delay or reverb with long decay times – the phase effect will smear across echoes in unpleasant ways.

How to Choose the Best Phaser Pedal for Your Playing Style
Choosing the best phaser pedal for your playing starts with identifying what tones you want most. If you want the EVH-inspired sweep, look for a 4-stage analog unit like the MXR Phase 90 or EHX Nano Small Stone. If you want experimental and complex phasing, look for variable stage counts and feedback control like the EHX Bad Stone. If you need gigging reliability, Boss PH-3 is the safest pick. If you want maximum value, the JOYO Vintage Phase or Kmise Vintage Phase deliver more than their price suggests.
Consider your pedalboard space. Mini-format phasers like the FLAMMA FC13 and EHX Nano Small Stone fit where full-size MXR Phase 90-sized boxes cannot. If you run a small board with limited real estate, a mini phaser is worth more than a larger one with extra controls. If you have plenty of space and want flexibility, a full-size multi-stage phaser makes sense.
Think about features that matter to you. Tap tempo is essential if you play to a click or alongside a drummer. Stereo I/O matters if you run two amps or use a stereo rig. Expression pedal control matters if you want to sweep your rate by foot during a solo. None of these features matter if you only need one classic tone – in that case, the MXR Phase 90 is the right answer.
Analog vs digital comes down to your ear. Trust your guitar and your amp – if you can borrow or try before you buy, that is the best test. Players chasing vintage character tend to prefer analog, while players chasing modern versatility tend to prefer digital. Either way, the pedal that you connect with sonically is the right pedal.
Frequently Asked Questions
What phaser pedal did Eddie Van Halen use?
Eddie Van Halen used the MXR Phase 90, specifically the original Script Logo version from the 1970s. His distinctive ‘Eruption’ and ‘Unchained’ tones rely on the Phase 90’s classic 4-stage analog sweep with a single Speed knob. The MXR Phase 95, which combines Phase 45 and Phase 90 circuits in one mini box, is the modern way to get a versatile Van Halen-style tone.
Which phaser did David Gilmour use?
David Gilmour has used several phasers over his career, including the MXR Phase 90 and the Electro-Harmonix Electric Mistress. For Pink Floyd’s classic 70s era tones, the Phase 90 was central to his clean chord swells and atmospheric lead work. Today, the EHX Nano Small Stone delivers that same Radiohead-meets-Pink Floyd sweep in a pedalboard-friendly size.
What phaser pedal did Jimmy Page use?
Jimmy Page used the MXR Phase 90 during Led Zeppelin’s classic era, particularly on songs like ‘Kashmir’ and ‘The Rain Song.’ His setup paired the Phase 90 with a Telecaster or Les Paul and a variety of Marshall amps. He also occasionally used the Shin-ei Companion FY-2, an early compact phaser that influenced later designs.
Are boutique phasers worth it compared to MXR or Boss?
Boutique phasers like the Asheville APH-12, Caroline Arigato, and Beetronics Larva offer unique character and features you cannot get from a stock MXR or Boss unit. The trade-off is price – a boutique phaser often costs two or three times as much, and reliability under heavy gigging is not always guaranteed. For most players, MXR or Boss offers the best price-to-performance ratio. Boutique builders win when you want something specific that the mainstream brands do not offer.
Where should I place a phaser in my signal chain?
Place your phaser either before your drive pedals for classic rock and clean tones, or inside your amp’s effects loop after drive for deeper, more dramatic sweeps. Most players experimenting with EVH-style phasing will place the phaser before drive. Shoegaze and ambient players tend to prefer phaser in the effects loop after drive. The exact placement depends on your amp, your other pedals, and the tone you want.
What is the difference between a phaser, flanger, and chorus?
A phaser uses all-pass filters to create moving notches in the frequency spectrum, producing a smooth watery sweep. A flanger uses a short modulated delay line that creates deeper, more dramatic comb-filtering – often described as a jet-plane whoosh. A chorus duplicates your signal with a slightly modulated delay to thicken and double the tone without obvious filtering. Phasers are the most subtle, flangers the most dramatic, and chorus the safest thickening effect.
Final Verdict: Which Phaser Pedal Should You Buy in 2026?
The best phaser pedal for guitars in 2026 is the MXR Phase 90, and it has been the best since 1974. Its combination of classic tone, rugged build, and single-knob simplicity makes it the right choice for most players. If you need budget value, the Kmise Vintage Phase delivers true bypass analog phasing at a price that costs less than a cable.
