This was probably discussed here, but I havent found anything... However: what is the optimal height of the pickups? I know that if they are too low, the sound would be poor, and if they are too high, the sound would be annoying. I believe it can be adjusted by hearing, but however - any suggegstions? Another question is if both pickups are to have the same height, or one should be higher than the other? I'm talking of 2 pickups mounted diagonally, like this: |o|___ |o|___ |o|___ |o||o| ___|o| ___|o| ___|o| Note: the underscores are not supposed to symbolize strings!
