Funkbox

Disco, funk, and Grateful Dead trippy

 

 

The Funkbox envelope filter rack effect module compares to the Musitronics Mu-Tron III, an effect used by Bootsy Collins, Jerry Garcia, and others to achieve their funky, grooving tones.

 

Description

Maybe not originally designed specifically for bass, but definitely most famously used by bass players.
