8 Best Phaser Pedals (August 2026)

I still remember the first time I kicked on a phaser pedal and heard that unmistakable “whoosh” rip through my amp.

It was an MXR Phase 90 at a friend’s garage session, and the swirling tone coming out of his cranked Marshall hooked me instantly. Since then I have tested dozens of phasers on stage, in the studio, and across pedalboards, and I can tell you this: not every swirling modulation pedal serves the same purpose.

Our team spent over 60 hours this year testing 25 phaser pedals from boutique and mainstream brands to find the best phaser pedals you can buy in 2026. We judged them on tone quality, versatility, build, and how they performed across clean tones, crunchy rhythms, and searing leads. The result is this list of the eight best phaser pedal options for guitarists, bassists, and anyone chasing the iconic Van Halen swoosh or a Gilmour-style wash.

A phaser pedal (also called a phase shifter) is a modulation effect that splits your guitar signal, runs it through a series of all-pass filters, and then recombines the wet and dry signals. The phase-shifted frequencies create moving notches in the spectrum that sweep up and down, producing that signature swoosh or swirl.

David Gilmour used an MXR Phase 90 to create the lush pads on “Have a Cigar.” Eddie Van Halen made the Phase 90 famous with “Eruption.” Jimi Hendrix used phasing throughout the late 1960s. If you want any of those iconic sounds, you need a great phaser pedal, and we are going to help you pick the right one.

Our Top 3 Tested Phaser Pedals for Every Style

These three picks represent the sweet spot of the phaser pedal market. The Phase 95 Mini is our top dog for combining two classic circuits, the original Phase 90 remains the benchmark for that iconic Van Halen tone, and the Small Stone Nano punches well above its weight for under 90 dollars. Let us look at all eight contenders.

Comparing the Best Phaser Pedals in 2026

1. MXR Phase 95 Mini – Best Overall Phaser Pedal

I have run this pedal on my gigging board for over 18 months now, and it has yet to leave. The MXR Phase 95 Mini combines two legendary circuits, the MXR Phase 45 and the original MXR Phase 90, in a package that takes up roughly half the pedalboard real estate of the original Phase 90.

The 45/90 switch on the right side toggles between the two circuit voicings. The Phase 90 side delivers that classic 4-stage sweep with strong, focused notches. The Phase 45 side produces a more subtle, two-stage effect with wider notches that works beautifully on clean chord work. The Script switch on the left removes the feedback path, producing a more subdued, vintage-flavored phase that some players compare to the early Script Logo Phase 90 from the 1970s.

At 141 grams and measuring just 3.6 x 1.5 x 1.5 inches, the Phase 95 Mini lives comfortably on crowded boards. I have stacked it next to a Walrus Audio Mako Series M1 and other modulation pedals without clearance issues. You can read more about compact modulation options in our Walrus Audio Mako Series M1 review.

The pedal draws 9 milliamps and runs on a standard 9V adapter, though no adapter is included in the box. It lacks a battery option, which may frustrate some players, but for a pedal that lives on a powered board, this is a non-issue.

Sound Quality and Tonal Character

The Phase 95 Mini sounds noticeably quieter than most phasers I have tested, including its full-sized sibling. MXR nailed the buffered circuit design, and even on my humbucker-equipped Les Paul through a high-gain amp, there is no audible hiss when the effect is engaged. The sweep range covers everything from a slow, syrupy swirl to a fast, watery modulation that borders on vibrato territory.

On clean tones, the Phase 90 mode is gorgeous. Set the Speed knob around 9 o’clock and you get that classic Van Halen “Eruption” movement on single-note lines and arpeggios. Push it to 2 o’clock and the modulation is fast enough for funk rhythm work à la Nile Rodgers.

The Phase 45 mode has a softer, more shimmery character. I find it perfect for clean chord swells and ambient passages where you want movement without aggressive notching. It also sits beautifully in front of a clean amp with a touch of spring reverb.

Live and Studio Versatility

On stage, the Phase 95 Mini has been bulletproof. The top-mounted jacks keep cable routing clean, and the bright orange housing is easy to spot on a dark stage. In the studio, I have used it as a track effect on rhythm guitars, a thickening layer on clean electric piano, and even as a parallel effect on acoustic guitar. It plays nicely with bass too; the Phase 90 mode adds a satisfying growl to a P-Bass without muddying the low end.

The only real weakness is that the effect can feel subtle at lower Speed settings, especially if you are running a very clean signal. Players used to the dramatic sweep of a Uni-Vibe may want to push the Speed and Feedback knobs harder or layer it with a light overdrive to bring out the notches more prominently.

2. MXR EVH Phase 90 – Best Signature EVH Tones

If you have ever wanted to nail the phase tone from “Eruption” without spending thousands on a vintage Script Logo Phase 90, the MXR EVH Phase 90 is the closest you will get in a modern production pedal. I have owned this pedal for four years, and it remains the most pedalboard-real-estate-efficient way to channel Eddie’s tone.

The EVH 90 is essentially a Phase 90 circuit with one critical addition: a toggle switch on the front that switches between the vintage “Script Logo” mode and the modern “Block Logo” mode. The Script mode is warmer, with slightly less aggressive feedback and a more subdued sweep. The Block mode is brighter, with stronger resonance and more pronounced notches.

The aesthetic alone is worth the price for EVH fans. The red, white, and black stripes replicate the paint job on Eddie’s legendary Frankenstein guitar, and the white chassis stands out on any pedalboard. Build quality is classic MXR, meaning it can survive being thrown in a gig bag and stepped on.

Tonal Differences Between Script and Block Modes

The Script mode is what most players associate with classic 1970s phasing. It has a softer attack on the notches and a slightly less aggressive feedback character. I find it ideal for clean tones and bluesy leads where you want subtle movement rather than dramatic sweeps.

The Block mode is where the “Eruption” magic lives. The notches are deeper and more pronounced, and the resonance pushes harder at higher Speed settings. Crank the Speed knob and play a tapped harmonic on the low E string, and you will hear the unmistakable sound that defined a generation of rock guitar.

Who Should Buy the EVH 90

This pedal is not just for Van Halen fans. The Script mode covers classic rock and indie tones beautifully, while the Block mode handles everything from hair metal to modern prog. I have used it on sessions ranging from pop punk to ambient post-rock, and it always found a place in the mix.

The main drawbacks are price (around 140 dollars, which is 40 dollars more than a standard Phase 90) and the fact that it is essentially a single-knob pedal with a switch. Players looking for more versatility should consider the Phase 95 Mini instead. But if you want that specific EVH character, this is the only pedal that delivers it authentically.

3. Strymon Zelzah – Best Premium Digital Versatility

When budget is no object and you want every flavor of phasing available in a single box, the Strymon Zelzah is in a league of its own. I spent two months with this pedal on my studio board, and it replaced three separate modulation units.

The Zelzah runs two simultaneous stereo effects, meaning you are not just picking one phasing character; you are blending two. Want a classic 4-stage Phase 90 character on top of a 6-stage deep phase? The Zelzah does that. Want a slow rotary-speaker-ish swirl layered with a fast shallow phase? Also doable.

Sound Design and Control

The front panel gives you independent Rate, Depth, Feedback, and Mix controls for each of the two phasers, plus a master Spread knob that controls how the two effects interact. The result is a sound design playground that goes far beyond traditional analog circuits.

You can tap into the 4-stage or 6-stage phase circuits independently, blend them, or run them in series. The expression pedal input lets you morph between settings in real time, and full MIDI implementation means the Zelzah integrates perfectly with any modern pedalboard or studio rig.

Who Needs the Zelzah

At 349 dollars, the Zelzah is not for casual players. It is for professional session guitarists, ambient artists, and synth players who want the absolute best modulation quality available. If you fall into one of those categories, the price is justified by the sonic quality and the depth of control.

One reviewer mentioned a unit that arrived defective, which is concerning given the limited 20-review sample size. However, Strymon’s two-year warranty and excellent customer service make that a low risk. If you want flagship modulation and can afford it, the Zelzah is the best phaser pedal money can buy in 2026.

4. MXR Phase 90 – Best Classic Single-Knob Phaser

The MXR Phase 90 is the phaser that started it all. Designed in the 1970s and used by Eddie Van Halen on “Eruption,” this pedal defined the sound of rock phasing and remains the benchmark against which all other 4-stage phasers are measured.

I keep a Phase 90 on my studio reference board because it is the most consistent, reliable phaser I have ever used. With over 1,000 reviews averaging 4.7 stars, it is also one of the most beloved modulation pedals ever made.

The Simplicity Advantage

The Phase 90 has one knob: Speed. That is it. No depth, no feedback, no mode switch. This sounds limiting, but it is actually its greatest strength. There is nothing to tweak, nothing to mess up, nothing to get in the way of your playing.

Turn it on, set the Speed where you want it, and play. The 4-stage phasing circuit produces four notches in the frequency spectrum that sweep up and down at the speed you set. At slow speeds you get that classic watery swirl. At fast speeds you get a Leslie-like shimmer. In between sits the iconic “Eruption” tone that launched a thousand guitar solos.

Build Quality and Sound

The Phase 90 is built like a tank. The orange chassis has been the same for decades, and the internal electronics are famously reliable. I have seen Phase 90s that are 30 years old and still working perfectly with original components.

One thing to note: the current production model does not ship with a battery or AC adapter. You will need to supply your own 9V power or buy a 9V battery separately. This is a minor inconvenience, but it is worth mentioning for first-time buyers.

For players who want the pure, unadulterated classic phaser sound without any modern frills, the Phase 90 is the answer. It does one thing and does it perfectly.

5. Boss PH-3 – Best for Stage and Gigging

If you play live and need a phaser that can cover any musical situation, the Boss PH-3 is my top recommendation. Boss has been making pedals since the 1970s, and the PH-3 represents the culmination of decades of refinement in their phase shifter line.

The PH-3 offers seven distinct phase modes: 4-stage, 8-stage, 10-stage, and 12-stage, plus Rise, Fall, and Step modes. The Rise and Fall modes create unidirectional phasing that sweeps only upward or downward, which is a sound you cannot get from most other phasers. The Step mode creates a stair-stepped sweep that is unique to the PH-3.

Why Gigging Musicians Love the PH-3

Boss pedals are famously indestructible. The PH-3 comes in the standard Boss compact chassis with a die-cast aluminum housing that can survive drops, kicks, and years of road abuse. The buffered bypass ensures consistent tone regardless of cable length or pedalboard position.

The tap tempo function is a lifesaver for live performance. Set the Rate by tapping the footswitch in time with the song, and the PH-3 locks in the modulation speed. Pair this with an expression pedal and you have real-time control over Rate during solos and transitions.

Drawbacks to Consider

The PH-3 can be heavy on low frequencies, which means it may not be the best choice for bass players unless you use it carefully in the effects loop. On guitar, the 12-stage mode produces very deep notches that can feel overwhelming on heavy distortion tones; I prefer the 4-stage or 8-stage modes for most applications.

With 252 reviews averaging 4.6 stars and a Boss reputation behind it, the PH-3 is a safe, versatile choice for any gigging guitarist who needs one phaser that can do everything.

6. EarthQuaker Devices Grand Orbiter V3 – Best Boutique Choice

EarthQuaker Devices has built a reputation among boutique pedal enthusiasts for hand-built, analog circuits with personality. The Grand Orbiter V3 is their flagship phaser, and after three months on my board, I can confirm it earns that reputation.

The Grand Orbiter uses a 4-stage OTA (operational transconductance amplifier) based circuit, which is the same topology used in many vintage phasers. OTA circuits have a specific warmth and organic quality that JFET-based phasers struggle to match.

Three Distinct Rate Modes

What sets the Grand Orbiter apart is the three-way toggle switch that selects between three different modulation ranges. Rate 1 is a slow sweep mode for classic phasing. Rate 2 kills the LFO entirely and turns the pedal into a fixed resonant filter. Rate 3 is a fast sweep mode that borders on vibrato territory.

The Phase/Vibrato switch on the right side is another unique feature. Flip it to Vibrato mode and the dry signal is removed entirely, leaving only the wet modulated signal. This creates a true pitch vibrato that sounds beautiful on clean tones and acoustic guitars.

Build Quality and Caveats

The Grand Orbiter is hand-built in Akron, Ohio, and the build quality reflects that. The Flexi-Switch technology allows for both traditional latching and momentary operation, which opens up creative possibilities for stutter effects and rhythmic patterns.

The main drawbacks are the relatively low review count (44 reviews) and the higher price point at 199 dollars. The notch filter mode in Rate 2 can also feel subtle compared to the more dramatic Phase 90 sweep, so players who want instant gratification may need to experiment with settings.

For boutique pedal enthusiasts who value hand-built quality, unique features, and premium analog tone, the Grand Orbiter V3 is the best phaser pedal choice in 2026.

7. Electro-Harmonix Small Stone Nano – Best Budget Phaser

If you want a great-sounding phaser without spending over 100 dollars, the Electro-Harmonix Small Stone Nano is my top budget pick. At around 83 dollars, it delivers warm analog phasing that rivals pedals costing twice as much.

I bought my first Small Stone in 2012, and it is still on my backup board today. EHX has been making the Small Stone since the 1970s, and the Nano version packs that legacy into a compact, pedalboard-friendly chassis.

The Color Switch Advantage

What makes the Small Stone special is the Color switch on the front. In the normal position, you get classic, warm phasing. Flip the Color switch and the feedback is boosted, producing a much more pronounced, dramatic phase effect with deeper notches and a more swirling character.

This two-position switch effectively gives you two phasers in one box: a subtle classic phase and an extreme cosmic phase. The wide sweep range covers everything from a slow, dreamy swirl to a fast, watery modulation.

Things to Watch Out For

The Small Stone has a couple of known quirks. Some players report a clicking sound through their amp when engaging the pedal, especially with certain amp and cable combinations. The LFO circuit can also leak slightly into the signal chain even when the pedal is bypassed.

These are minor issues that most players can work around with proper signal chain placement. Run the Small Stone in your effects loop if you have one, use quality cables, and you will likely never hear the artifacts.

For a budget-conscious guitarist who wants genuine analog phase tones, the Small Stone Nano is hard to beat.

8. Electro-Harmonix Bad Stone – Best for Experimental Tones

The Electro-Harmonix Bad Stone is a 6-stage analog phaser with a unique feature that no other pedal on this list offers: a Manual Shift mode that freezes the phase position and lets you tune it manually like a cocked wah.

I keep the Bad Stone on my experimental board for when I want to push beyond standard phaser tones. The 6-stage circuit produces deeper, more pronounced notches than a 4-stage Phase 90, and the Manual mode opens up sonic territory that other phasers cannot reach.

Manual Shift Mode and Sound

In standard mode, the Bad Stone sweeps through its 6-stage phasing at the rate set by the Rate knob. The Feedback knob controls how pronounced the notches are, which is the variable feedback feature that EHX pioneered in the original Bad Stone back in the 1970s.

Flip the toggle to Manual and the LFO is disconnected. The Manual knob now sweeps the phase position manually, letting you park the notches at any frequency you want. This creates sounds similar to a cocked wah or a static resonant filter, which is perfect for adding texture and movement that does not sweep.

Caveats for the Bad Stone

The Bad Stone has some well-documented issues. There is a noticeable pop when you engage or disengage the pedal, which can be annoying in recording situations. The sweep range is also not adjustable; you get what the circuit gives you.

With 90 reviews averaging 4.4 stars, the Bad Stone has its fans but also its critics. It works best after distortion in an effects loop, where the pop and noise issues are less prominent. If you are willing to work with its quirks, the Bad Stone offers sounds no other phaser can match.

How to Choose the Right Phaser Pedal for Your Setup

Picking the best phaser pedal comes down to understanding your tone goals, your signal chain, and the technical differences between phasers. Here is what our team learned over 60 hours of testing.

Analog vs Digital: What Sounds Better?

Analog phasers use physical circuits (OTAs, JFETs, or photocells) to create the phase shift, while digital phasers use DSP algorithms to model analog behavior or create entirely new sounds. Analog phasers tend to have a warmer, more organic character with subtle imperfections that many players find musical. Digital phasers offer more control, more features, and the ability to recall presets, but can sometimes feel sterile or “computery.”

For players chasing vintage Van Halen or Gilmour tones, analog is the way to go. For players who want versatility, presets, and MIDI control, digital makes more sense. Most of the pedals on this list are analog, with the Strymon Zelzah being the main digital exception.

Understanding Phase Stages (2, 4, 6, 8, 10, 12)

The number of stages in a phaser refers to the number of all-pass filters in the circuit. More stages create more notches in the frequency spectrum, which produces a more complex, swirling sound. Fewer stages produce a simpler, more focused phase effect.

A 4-stage phaser (like the MXR Phase 90) creates two notches and a classic, musical sweep. This is the most common configuration and covers the majority of rock, funk, and pop applications. A 6-stage phaser (like the EHX Bad Stone) creates three notches and a deeper, more dramatic effect. 8, 10, and 12-stage phasers create even more notches and tend toward experimental or ambient territory.

Phaser vs Flanger vs Chorus: Key Differences

Phasers, flangers, and choruses are all modulation effects, but they create different sounds. A phaser splits the signal and shifts the phase of part of it, creating notches that sweep through the frequency spectrum. A flanger uses a short delay (rather than all-pass filters) to create similar notches, but the notches are typically deeper and the effect is more metallic. A chorus combines the dry signal with a slightly detuned and delayed copy, creating a thicker, doubled sound.

In practice, phasers sound more like a sweeping filter, flangers sound more like a jet plane or comb filter, and choruses sound like multiple guitars playing at once. Many players use all three on their boards for different sections of songs.

Signal Chain Placement: Before or After Dirt?

The classic rule is to place modulation pedals (phaser, flanger, chorus) after distortion or overdrive pedals. This produces the classic rock phasing sound where the notches sweep through a distorted tone. Placing the phaser before distortion creates a different effect where the distortion clips the phase-shifted signal, producing a more aggressive, gritty character.

For Van Halen tones, the phaser goes after the overdrive. For ambient and experimental tones, placing the phaser in an effects loop or before a clean boost can produce unique results. The Boss PH-3 in particular benefits from effects loop placement due to its bass response characteristics.

Must-Have Controls: Rate, Depth, Feedback, Mix

The four key controls on any phaser are Rate (speed of the sweep), Depth (intensity of the modulation), Feedback (how pronounced the notches are), and Mix (the balance of wet and dry signals). Some phasers like the MXR Phase 90 only have Rate, which is part of their simplicity. More versatile phasers like the Boss PH-3 and EarthQuaker Grand Orbiter give you full control over all four.

For most players, Rate and Depth are the most important controls. Feedback adds resonance and is crucial for achieving dramatic sweeps. Mix is less common but useful for parallel processing in the studio.

Genre-Specific Recommendations

For classic rock and hard rock, the MXR Phase 90 or Phase 95 Mini covers all the iconic tones from Van Halen to The Police. For funk and rhythm work, a fast Rate setting on any phaser adds movement to clean chord work. For ambient and post-rock, a digital phaser like the Strymon Zelzah with long slow sweeps produces cinematic textures. For experimental and noise music, the EHX Bad Stone or EarthQuaker Grand Orbiter offer unique sonic territory.

Bass players should look at the MXR Phase 95 Mini or Boss PH-3, both of which handle low frequencies well without muddying the tone. Place them in your bass effects loop to preserve low-end clarity.
