This is sort of hard to describe, but here goes. I have an older Ernie Ball passive mono volume pedal (the one with the jacks on the right side instead of the front). I am currently trying to use it as an expression pedal in a MIDI controller that I am making. I am connecting the tip to positive voltage, the sleeve to ground, and the ring is my input. Therefore, with the heel down, I should get 0V (shorted to ground), and with the toe down, I should get 5V.
The problem is, with the toe down, I am only getting around 3.3V. If I pull on the string when the toe is down, my voltage continues to go up, which tells me that the pedal itself is not rolling the pot to full tilt. To be an effective expression pedal, I would really like for it to go all the way, of course.
Do any of you guys have a suggestion on how to make the pedal mechanism turn the pot the full length? Thanks for your help.
