I have my tokai les paul copy (LS160) wired up with CTS pots.
on both volume pots, when i have a really high gain tone set up at high volume, there is a constant deep hum from my speakers.
Its only noticable on very high gain set up's, but it totally dissappears if volume is below 3 or above 8.

It happens for both pots. Ive checked earthing and from a wiring perspective, everything is fine.

is there a know issue with some pots where they are simply noisier in the middle of their range?
