DIY Volume Pedal (Updated)

Posted on May 2nd, 2015

I finally built my ‘drop-in’ DIY volume pedal circuit. The circuit can be plugged directly into a Dunlop Cry Baby. However, the potentiometer in wah pedals uses a different taper, ICAR I believe. Because of the way the human ear responds to sound a logarithmic or audio taper is preferred but existing wah pots will work.

I have included a circuit a strip/vero board layout.

The strip/vero board layout can be used a ‘drop-in’ board to turn a Dunlop Cry Baby Wah into a DIY volume pedal.
