I used this to convert an old Crybaby pedal into an expression pedal for my Helix. Very easy to do and it works perfectly. This is the only decent pot I could find for this purpose - it had to be 10K. Freakin' expensive, but the only game in town. Beats paying a crazy $120 for a Mission pedal. So $10 for a broken wah, $20 for this, I came out way ahead.
