Hi johnkbrock,

It’s recommended to use an expression pedal with a 10K pot for best performance. It may be the case that the 10K output is not configured properly, as this output can be set momentary or latching and also have its polarity reversed. You should consult the Lehle manual on page 9 to see all the modes and make sure it’s configured correctly. The bottom of the pedal features soft buttons that configure the different modes.
