Musitronics Mu-Tron III

Musitronics · pedal

The Mu-Tron III is the classic 1970s envelope filter, an auto-wah that responds to pick dynamics with a vocal, quacky sweep. Used by Andy Summers and many funk and fusion players, it delivers expressive, dynamic filter sweeps from subtle to dramatic. It suits funk rhythm, fusion and experimental playing where touch-responsive, vowel-like filtering is wanted.
