I have tried every other envelope type effect, its one of my favorites, and while the WMD Fatman comes close there is no other pedal that gives up the funk (Or the Jerry if that's your thing) better than the Mutron III You can hear the difference mainly when the whole band is playing- you don't get the same level drop most envelope followers have. A Classic and unbeatable really...
