DIY volume/expression pedal

I made this pedal for myself a while ago. I wanted a volume pedal that I can also use an expression pedal when I need to. I just switch the pedal to expression with the 4pdt footswitch I put in the case. I also installed a potentiometer I can adjust the minimum volume with.

Here’s a video I did about the build.

I have this on my pedal board and I had to do a custom cable so I can use this with my new Hotone ampero mini. There will be a video about that and my board soon.

Here’s the wiring diagram if you want to make your own. The pot values you need might change depending on your setup and so on so I suggest you do some research on that.

I ordered my enclosure here: https://uraltone.com/valualimiinikotelo-wah.html A wah enclosure will do and you could find a used unworking wah for cheap, I would probably do this since this enclosure had some issues I had to figure out.

I used a potentiometer like this https://www.tubeampdoctor.com/en/wah-pot-100k-fits-fulltone-clyde-wah-dunlop-cry-baby You might need a different value depending on your gear. Do a search about volume pedals and see what should be good for you.

The switch is this https://www.musikding.de/4PDT-footswitch You can find these cheaper at https://www.taydaelectronics.com/ where I get my electronics.

Then you just need some wire and the tools.
