What expression pedal can I use?

We have tested the Moog EP-2/EP-3, and Mission Engineering EP-25K, and they will all work with our pedals to varying degrees.  (There may be others but we haven’t tested them yet.)

We recommend using expression pedals that have a minimum 25k ohm or higher potentiometer such as as the Moog EP-3 or Mission Engineering EP-25k.
