Volume Pedal / Expression Pedal

thingiverse

This pedal chassis and other printable components can be used to create any variable resistor (potentiometer) based audio pedal. My primary objective was to just create an expression pedal that could be used in conjunction with my [Midi BLE Pedal](https://www.thingiverse.com/thing:4134488), but I thought I'd add a few more ideas for a volume, or tone pedal. Enjoy! ## Volume Pedal ### Parts - All Parts printed, including the Double 1/4" Mount Chassis - 2 x 1/4" Mono Jacks - 10K Potentiometer ### TODO: Wiring diagram ## Tone Pedal ### Parts - All Parts printed, including the Double 1/4" Mount Chassis - 2 x 1/4" Mono Jacks - 10K Potentiometer - Tone Capacitor ### TODO: Wiring diagram ## Wah or Other Passthrough Pedal ### Parts - All Parts printed, including the Double 1/4" Mount Chassis - 2 x 1/4" Mono Jacks - 10K Potentiometer - Wah, or other Sound Circuit ### TODO: Wiring diagram ## Expression Pedal ### Parts - All Parts printed, including the Single 1/4" Mount Chassis - 1/4" Stereo Jack - 10K Potentiometer ### TODO: Wiring diagram ## General Parts List - Potentiometer - 10K Ohm - 1/4" knurled shaft - Available from [Sayal](https://shop.sayal.com/products/rpa-10k-524b) or [DigiKey](https://www.digikey.ca/en/products/detail/tt-electronics-bi/P160KNP-0QC20B10K/4780752) - 1 x 1/4" Stereo Jack (for an expression pedal) - 2 x 1/4" Mono Jacks (for a volume pedal, tone pedal, wah pedal, or any other pedal, where the wound passes through it via in/out) - Tone Capacitor - TODO: specs ## Note from the Creator I strongly believe that things like this should be freely available on the internet, but I also believe that appreciation should be shown if you get use out of it, or find it useful.
