Volume Pedal / Expression Pedal
thingiverse
This pedal chassis and other printable components can be used to create a wide variety of variable resistor (potentiometer) based audio pedals. My primary goal was to design 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 some extra ideas for a volume, or tone pedal. Enjoy! ## Volume Pedal ### Parts Needed - All Parts printed, including the Double 1/4" Mount Chassis - 2 x 1/4" Mono Jacks - 10K Potentiometer ### To-Do List: Wiring Diagram ## Tone Pedal ### Parts Needed - All Parts printed, including the Double 1/4" Mount Chassis - 2 x 1/4" Mono Jacks - 10K Potentiometer - Tone Capacitor ### To-Do List: Wiring Diagram ## Wah or Other Passthrough Pedal ### Parts Needed - All Parts printed, including the Double 1/4" Mount Chassis - 2 x 1/4" Mono Jacks - 10K Potentiometer - Wah, or other Sound Circuit ### To-Do List: Wiring Diagram ## Expression Pedal ### Parts Needed - All Parts printed, including the Single 1/4" Mount Chassis - 1/4" Stereo Jack - 10K Potentiometer ### To-Do List: 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 signal 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 think that appreciation should be shown if you get use out of it, or find it useful.
