I have a MIM strat, and when the middle tone knob is more than 0 the sound cuts in and out, very much like a tremolo effect, especially on the higher frets.. But when the tone knob is at 0, all is well? Is there something wrong with my tone pot?
yes. but might be the amp?
It *could* be wolf-tones that you get when the pickups are too close to the strings, how close are they?
