What are they for? I have a Schecter elite 5. It has EMG Hz pickups which are passive but it has an active pre amp. Today I decided to change the battery and noticed two tiny switches conected to the electronics. They have the numbers 1 and 2 above them, the word "ON" below one of the switches and some other numbers that mean nothing to me. My old Ibanez that had EMG's had something similar that I believe changed the midrange setting. My Schecter doesn't have a midrange control. Bass/treble only. When I move the switches I hear a very quiet pop like something is happening but no real tonal changes at all. Any idea what these are for?
