What we have here is a very bad old picture of a set of bass pedals for a Farfisa Pro Duo. This set up is truly one on beauty for the organist who gets a volume pedal for each keyboard, a full set of bass pedals, and all of the controls for the bass pedal sounds in easy to use dials and switches. It comes complete in an incredibly rare fake wood housing.
The ever elusive Farfisa Sferasound pedal photographed in the wild (below). The Sferasound was built into the standard 70s era Farfisa plastic wah housing, and supposedly was some sort of chorus-y, rotating speaker, phaser-type effect.
