Expression Pedal Malfunctioning With Amp

Post by funkybeatz911 » Wed Jan 27, 2016 7:53 pm


I am sporting a moog ep-2 or ep-3, honestly I can't remember which specific model it is because I bought it 2 years ago. However, what I do know is that I have been trying to use it with my Sub Phatty to control volume for swells and crescendo in concert.

It works when I listen through headphones, but as soon as I plug into an amp I get either no action from the expression pedal or reverse action (the volume swells down as I push the pedal to the floor and swells up as I ease off the pedal.)

Can someone please help me troubleshoot to get it working properly?

Btw, I have the pedal plugged into the input vol cv jack on the Sub Phatty so and I have had success using other expression pedals. I used a Yamaha that did work properly.
