So I've had this HSS strat for two years, my first and only electric guitar. I've been focused on learning just guitar playing (fretting, strumming, fret board knowledge etc) and have just recently played around with the tone controls. And I am confused as I hear no difference between when the knob is at 1 and at 10. I've tried every combination of the three pickups and the two tone pots. I do hear a difference in the three pickups, but the tone controls seem to have no effect. The tone controls aren't that subtle, are they? A difference between 1 and 10 should be evident, shouldn't it? Anyway, aside from the question of whether I should be hearing a difference, are there any common problems that would cause this? My amp, by the way, is a Champ Micro (no tone control on the amp).
