Really clever design!

[@chamberofsounds]

Thanks guys. I'm running my guitar into it and then going into a EH Ring Thing. I can do the mod if you have the Ernie Ball pedal...

[@sushimandaddi]

THATS AWESOME what is your input???

[@MelaneeBand]

so how do you leave in in full on position?

I know this is an old video but I've been looking into building effects pedals and I want to do something like this. Do you think it's possible to make one so it works in reverse, so covering the resistor cuts the sound and pulling away from it makes it louder?

I'm also looking for the answer to the same question
