Much like my other list compiling all pedals with the tap-tempo feature, this list focuses specifically on pedals that can use expression pedals. I'm expecting this list to be pretty long. The pedal must be able to use an expression pedal (or have one built-in, like a wah pedal) to be on this list. If it can use an external footswitch, but not an expression pedal, it doesn't count. Post any pedals you can think of that use expression pedals! Please also briefly note what the expression pedal can control. If it can control more than three different features, I'll note it as [multiple parameters].
