The fOXX Down Machine was a wah-wah pedal designed for bass guitar, made by Ridinger Associates Inc of Chatsworth, California, in the early 1970s. TONEHOME describes it as "presumably the first Wah Wah designed for bass," and the pedal carries a 1974 date with a retail price that year of $69.95 USD1. Guitar Player's Dave Hunter likewise lists the Down Machine as "a bass wah-wah"2.
A wah-wah designed for bass
Wah-wah pedals sweep a filter across the signal, and most were voiced with guitar in mind. The Down Machine was built around the bass guitar instead, which is what makes it notable in the history of bass pedals and of wah-wah pedals generally. TONEHOME's claim that it was "presumably the first Wah Wah designed for bass"1 positions it as an early, purpose-built option for bass players who wanted the effect without losing low end.
Reliability and repair
The Down Machine has one well-documented weakness. According to TONEHOME, "for unknown reasons the capacitors had a strong tendency to dry out fast," which is why "working units are pretty scarce today"1.
The capacitor fault is the reason most Down Machines stopped working. TONEHOME describes it as one that "would have been an easy fix"1, so a non-working example is not necessarily a lost cause for a player comfortable with basic component replacement.
The scarcity is not only a matter of electronics. TONEHOME notes that "during the 80s and 90s - before people became aware of how good these Down Machines really are - people trashed their non working pedals"1, which thinned the supply of units further.
