Music's effects pedals icon. Since 1968.

Welcome to Electro-Harmonix, creators of the most iconic musical effects pedals such as the Big Muff Pi, POG, Memory Man & Small Clone.

Back in 1968, guitar amps were intentionally engineered to keep players from experimenting with distorted sounds. We changed all that. For over 50 years, Mike Matthews and EHX have been proud to contribute to many of the most famous recordings in music history.

The Adrian Belew Echoflanger Reissue is a limited-edition tribute with all the bells, whistles, warbles, and extremes of the original plus modern construction with a few new tricks (and an old one discovered by Adrian himself!). Equal parts smooth operator and agent of chaos, this multi-mode modulator creates classic chorus and flanger sounds with the ability to take the effects beyond the limits to design totally unique and twisted tone.

From his start with Frank Zappa to stints with David Bowie and the Talking Heads and making his mark with King Crimson, Adrian Belew is a true tonal innovator with style and spirit like no other. He pushed effects well beyond their supposed limits to create a remarkable sonic signature, with the Echoflanger center stage for his most iconic sounds.

This modern, signature-edition Adrian Belew Echoflanger is built to replicate the sounds of the original, from lush modulations to out-of-bounds auditory explorations. Included now is Adrian’s custom CHORUS + FLANGE setting, which he discovered by parking the knob between the two modes and blends the sweep of a flanger and the thickening echo of chorus.

The Op-Amp Big Muff has "a huge, crushing Big Muff sound with more crunch… great for grungy, wall-of-sound distortion, heavy rhythm playing and heavy leads."
