I’ve had the same problem with mine.
I ended up putting mine in its own loop from an A-B box that has a ground lift separating it from the rest of my signal chain.
I would rather have it inline with the rest of my pedals but this will work for now.
This is what I picked up from radio-shack “1meg linear taper potentiometer”
.5watts rated power
so should i wire it exactly like the original or backwards?
could I use a regular 1meg pot and just wire it backwards?
