  • Flanging is a classic stompbox effect beloved by guitarists of all styles.
  • We look at the best flanger pedals for sweeps, subtle detuning, and full-on modulation madness.
  • From analog richness to digital versatility, you’ll find plenty of options here.
  • Also, check out our pick of the best flanger plugins!

Flange is a classic modulation effect with roots in analog tape machines, where engineers would press down on the “flanges” on the tape machine to vary the speed. Flanger pedals give guitarists this unique effect in a simple stompbox. The sound of a flanger pedal can range from subtle sweeping to full on “jet engine” effects.

Like most things guitar-related, not all flanger pedals are created equal, and this is complicated by the individual preferences of each guitarist as well. This list features a variety of options for flanging, from simple, no-frills pedals to unique and versatile modulation machines.

The Electro-Harmonix Stereo Electric Mistress is a unique and unusual pedal. It can give you stellar results whether you’re looking for wild experimentation or traditional flanging.

It comes with all the quality, great sound, and durability that Electro-Harmonix is known for. The Stereo Electric Mistress is our pick for best flanger pedal on this list!


  • Fantastic modulated tones
  • Flange, chorus, and filter effects
  • Rate, Flanger Depth, and Chorus Depth controls
  • True stereo operation
  • Heavy-duty construction


The EHX Stereo Electric Mistress is a flanger and chorus combo pedal that works wonderfully. Often, when you combine two or more effects in the same pedal, the results tend to be lackluster.

This EHX flanger pedal is digital and sports a very simple design that actually helps its functionality. It features controls for Rate, Flanger Depth, Chorus Depth, and a footswitch.

This modulation pedal enables you to use both the flanger and chorus effects independently or combined together.

The Rate knob gives you quite a bit of range and is sensitive to how you play your instrument. If you take it to the 10 o’clock position, you enter the featured Filter Matrix Mode for flanger which spans all the way to 12 o’clock position. In this mode, you get to freeze the effect.

Even though the Stereo Electric Mistress is a digital pedal, it sounds quite organic and won’t upset anyone after classic “analog” vibes.

This unit also features heavy-duty construction, a LED indicator, and a rugged footswitch. It works with a 9V DC power supply which is included when you buy this pedal.

Simply said, the Stereo Electric Mistress is one of the best in the market, especially considering its price.

Well, Universal Audio has jumped in the pedal game with quite a splash!

Their first ever stompbox pedal line draws from their finest DSP-powered emulations of classic effects. These DSP algorithms have been packed into thoughtfully designed and durable guitar pedals that are ideal for discerning players who want the best.

The Universal Audio Astra Modulation Machine gives you three legendary modulation effects at your feet: a bucket brigade chorus, a flanger/doubler, and a vintage amp tremolo.


  • 3 classic modulation effect emulations powered by UAD DSP
  • Chorus Brigade conjures up the 1970s big gray unit’s lush, analog chorus and vibrato
  • Flanger/Doubler re-creates the characterful blueface bucket brigade rackmount flanger
  • Trem 65 offers warm, opto tube-style tremolo with sine and square wave modes
  • Operates in mono, dual-mono, and stereo modes with automatic mono/stereo detection


The Astra Modulation Machine is a relatively new arrival, and it comes from one of the most respected companies in audio.

It features true bypass switching and an optional buffered bypass, which keeps your core tone intact while you layer on your modulation mojo.

This pedal reproduces the sound of the legendary bright blue rack-unit flanger and doubler that was released in the late seventies and was part of the rig of professional guitarists during the 1980s and 1990s. Universal Audio captured this “meta” effect, which used bucket-brigade circuitry to mimic the analog tape flanging effect that was heavily employed by psychedelic bands in the 1960s.

The Flanger/Doubler on the Astra Modulation Machine offers you a range of effects, from unstable-tape-machine wow and flutter to underwater whooshing, all with gorgeous tone and loads of grit.

Besides flanging, this pedal also features a beautiful “Chorus Brigade” (BBD style analog), a Trem 65 for warm opto tube-style tremolo with sine and square wave modes, as well as the new X90 Phaser and Dharma Trem 61.

If you like a true modulation workhorse that offers you high quality and flexibility, the Universal Audio Astra Modulation Machine is for you.

  • Barber Pole Up (continuously ascending Shepard tone)
  • Barber Pole Down (continuously descending Shepard tone)
  • Trigger Up (infinitely ascending sweep that restarts with each pick attack or press of the Tap/Trigger switch)
  • Trigger Down (infinitely descending sweep that restarts with each pick attack or press of the Tap/Trigger switch)
  • Step (rhythmic, sequencer-like stepped sweeps in both directions)
  • Random (chaotic flange effects, similar to a synthesizer’s “sample and hold” function).

That’s enough flanging to last you a lifetime!

Additionally, the Pyramids Stereo Flange also features a Tap switch with a subdivision toggle that allows you to key into the tempo of your songs, quite an unusual trait for traditional flanger devices.

This pedal uses a proprietary 24-bit/96kHz DSP architecture, for superior stereo depth and clarity. It also features a Flexi-switch, which allows latching or momentary operation to add texture to a chorus or sweeten a quick harmonic occasionally.

The Pyramids Stereo Flange also includes a Mix knob that lets you dial in the right amount of sweetening, and true bypass switching preserves the integrity of your signal when out of the loop.

In short, this is one of the most impressive flanger pedals on the market today.

4. Keeley Bubble Tron Dynamic Flanger Phaser (Most Unique)

Pedal guru Robert Keeley designed a very unique flanger pedal with the Keeley Bubble Tron. This pedal features signal manipulation techniques reminiscent of guitar iconoclast Frank Zappa.

The Tron Dynamic is a flanger/phaser pedal that dynamically responds to your pick attack, cycling only as you play. If you want a truly unique flanger pedal, the Bubble Tron is hard to beat.


  • Dynamic flanger/phaser pedal with Random Stepped Filter
  • Incorporates signal manipulation techniques employed by the legendary Frank Zappa
  • Dynamically responds to your pick attack, cycling only as you play
  • Combine its 3 modes of operation in uniquely creative ways
  • It may be switched internally for standard (non-dynamic) phase/flange operation


The Keeley Bubble Tron Dynamic Flanger Phaser pedal features a Random Stepped Filter with proprietary M-Style Synth bandpass shaping as well as three modes of operation.

Robert Keeley designed this pedal based on Frank Zappa’s infamous MicMix DynaFlanger effect. This effect was central to Zappa’s lead guitar sounds that relied upon envelope-based dynamic flanging.

The effect starts and stops based on your pick attack, effectively creating an “envelope” that can be used to modulate another part of the circuit.

In other words, with the Bubble Tron, you’ll get a flanger effect that is unique to your playing.

Additionally, the Bubble Tron offers a choice of either positive or negative feedback via its FDBK control, allowing you to customize your sound even further.

The Bubble Tron also features two phasers: Standard and DynaMoPhase. The standard phaser sports an LFO with a Rate Control that sets its speed while depth is controlled dynamically. The other is a true Dynamic Phaser that starts and stops according to your pick attack.

To top it off, the Bubble Tron also features a Filter Section. This is the only effect on board that isn’t dynamic.

You can deploy the Filter to control effect ramping, and explore degrees of randomness with the Shape Control. The Sensitivity Control is designed to operate like a vintage synth-style bandpass filter, and with it, you can create impressive keyboard-like sounds.

If you’re into sonic experimentation and appreciate having your very own distinctive sound, then the Keeley Bubble Tron is a fantastic choice for you.
