Oscillation

[Herr Masel]

So the tonebender I built is oscillating, as in it does a little tremolo sometimes. I think it's a ground problem, looking at older threads reinforced this, because when I touch the volume pot it stops it. So I should add a ground to the pot right? but on which lug, or it doesn't matter, could be on any part of it (that is metal obviously)?

Ground the CASE of the pot. You may have to file the pot case first, it can be hard to solder to a pot case.
