Mu-Tron, short for Musitronics, hails from the '70s, bringing all the funky psychedelic phasing, flanging, and octave effects of the decade with it. Founded in '72, Mu-Tron aimed at bringing players filtering effects utilizing synthesizer components, giving musicians ultra high-quality pedals to play with. And the legacy of Mu-Tron's high-quality effects has lasted decades; the famous Mu-Tron Bi-Phase appears heavily on Smashing Pumpkins' Siamese Dream, and the Mu-Tron III envelope filter is an essential for tons of funk musicians to this day, making appearances on records by artists ranging from Jerry Garcia to Stevie Wonder. There are many clones out there, but there was only one Mu-Tron -- buy the original effects today on Reverb.
