my volume knob was noisy so i thought it needed cleaning.
but strangely the problem lies somewhere else.

the pots of my guitar are assembled this way.

ring#1 looped through the pot's dial
pot poked through hole of wood
ring#2 looped through pot's dial (above the wood)
nut tightened above ring#2
knob tightened

both the volume and tone pots make scratchy sounds when turned UNLESS i remove ring#1.
i thought the rings were there to reduce direct pressure on the pot when you tighten the nut. now i have both pots without ring#1.
the noise problem has been solved but do i harm the pots this way?
