Popular MXR Effects Pedals

Blues player? Metal shredder? Indie rocker? Doesn’t matter. Every MXR pedal does its own thing, and does it right. We’re not trying to make one pedal that sorta works for everyone – each one nails a specific sound that players actually need. From bedroom jams to sold-out venues, these pedals just work. Simple controls that make sense, built tough enough to survive real touring, and they sound exactly the same whether you’re practicing at home or cranking it on stage.

MXR Pedals Buying Guide

Where to start with MXR, by sound.

Modulation: Phase 90, Phase 95, Analog Chorus & Flanger

The Phase 90 is the classic one-knob phaser; the Phase 95 Mini adds Phase 45 mode and a script switch. For chorus, the Analog Chorus and Micro Chorus cover lush to subtle; the EVH117 Flanger handles jet-plane sweeps.

Drive: Timmy, Duke of Tone, EVH 5150 & Super Badass

Timmy and Duke of Tone are transparent overdrives, the EVH 5150 Overdrive is high-gain, and the Super Badass Distortion and Fullbore Metal go heavier. The Distortion+ is the original 1970s sound.

Dynamics & EQ: Dyna Comp, Micro Amp, 10 Band & 6 Band EQ

The Dyna Comp compressor and Micro Amp clean boost are pedalboard staples. Use the M108S Ten Band EQ or M109S Six Band EQ to shape tone or boost solos.

MXR Bass Pedals

Bassists choose the M87 Bass Compressor, Bass Octave Deluxe, Bass Envelope Filter, M81 Bass Preamp and the MXR Bass Synth for synth-bass sounds.

Delay, Looper & Power

The Carbon Copy analog delay is MXR’s best-known delay. Add the Clone Looper for practice and an Iso-Brick for isolated, noise-free power.

MXR History: From Rochester to Dunlop

MXR was founded in 1972 in Rochester, New York, by Keith Barr and Terry Sherwood. Their small, battery-powered stompboxes — the Phase 90, Distortion+, Dyna Comp and Blue Box — set the template for the modern guitar pedal.

The Phase 90 became famous on early Van Halen records, and the Dyna Comp became a Nashville and funk staple. In 1987 Jim Dunlop acquired the MXR brand and relaunched the classic circuits.

Under Dunlop, MXR grew into a full line: the Carbon Copy analog delay, Timmy and Duke of Tone overdrives, the M108S Ten Band EQ, EVH signature pedals, and a dedicated bass range including the M87 Bass Compressor, M80 Bass D.I.+ and the MXR Bass Synth.

Today MXR pedals are made in the USA and stay popular for their rugged housings, simple controls and true-bypass or buffered designs.

The MXR Iso-Brick power supplies and Clone Looper round out the line for building a complete pedalboard.

MXR Pedals FAQ

Which MXR pedals are the most popular?

The Phase 90, Dyna Comp, Carbon Copy, Distortion+, Micro Amp and the M108S Ten Band EQ are MXR’s best sellers. For bass players, the Bass Synth and M87 Bass Compressor lead the list.

What power supply do MXR pedals need?

Most MXR pedals run on a standard 9V DC center-negative adapter or a 9V battery. Some, like the Ten Band EQ, need 18V for extra headroom — an MXR Iso-Brick or DC Brick powers a full board.

Is the MXR Carbon Copy analog?

Yes. The Carbon Copy is a bucket-brigade analog delay with up to 600 ms of delay time and an optional modulation switch. The Carbon Copy Deluxe adds tap tempo.

What does the MXR Bass Synth do?

The MXR Bass Synth tracks your bass notes and turns them into synth tones with built-in presets, sub-octaves and filter controls — no pickup changes needed.

Should I get the MXR 10 band EQ or 6 band EQ?

The M108S Ten Band EQ gives finer control and two outputs, ideal for shaping tone on a big board. The M109S Six Band EQ is smaller and simpler for quick mid boosts and solos.
