Hello friends,
I have a stereo volume pedal I've been using for guitar. It works great, but now I find a need to use it temporarily after the output stage of my MIDI keyboard rig. Ernie ball makes two separate pedals for these purposes, but I'm wondering if purchasing a whole new pedal is necessary. When using the "passive version" (schematic below) with my keyboard system, the taper of the pedal is almost logarithmic in it's perceived response (meaning heel-down is nothing, and still almost nothing until last 10% of travel). No matter how hard I drive the input, the taper is still the same. Why?
The pedal they make for "Active" circuits has a 25k audio pot instead of the 500k linear in mine. What accounts for the difference in response, and is there any way to use the pedal for my needs without modifying it and voiding the warranty (or buying a whole new pedal for $140) Thanks!
