Controlling guitar effects processor with Arduino
by eimink on May.18, 2010, under Hacks
Today at work, during a coffee break of course, we were tossing around ideas about how to control guitar effects with accelerometer – like doing a whammy dive-bomb by doing a motion with guitar. Of course that would need the accelerometer to be built in to the instrument itself, but that’s not a problem. But where to find a suitable effects processor that a) has all necessary effects and b) has suitable input capabilities to accept external control of the effects? It turned out that I have a suitable device already!
Years ago I bought a Digitech RP50 effect processor for guitar. It’s not very good piece of gear but it has worked for me while practicing at home, and even during some home studio sessions. The nice thing about the RP50 is that it has a 6,3mm jack labeled Control In in the back. The user manual says that one can hook up a passive volume pedal to it and use it to control master volume, wah or whammy effects on the processor. Nice. Now, how can I emulate a passive volume pedal with Arduino?
