howdy! i'm wondering if there's any way to frankenstein an old ernie ball 6165 stereo/volume pan into a volume/expression pedal. i'd like an expression pedal for my line 6 fm4, but the plastic frame of an ex1 isn't something i want to toy around with. i know they use 10k ohm linear taper pots, so would there be a way to use the toe-toggle of the 6165 to switch between expression and volume functions? it doesn't yet seem impossible to me. i know very little on electronics, so any information would be greatly appreciated. thanks pros!
