Even though this thread could be placed in "PU's" section,it seems equally proper to put it here.... The question is: What is supposed to be the famous "sweet spot"? I'm looking for some explanations of a more "technical" nature,such as WHY the sweet spot was choosen where it's already "estabilished".It was a "trial-and-error" type of decision,or it's a precise harmonic configuration picked up from the string that leaded to this? Also,related on theme:it's a big gap of information on this aspect...only some modest info's on MM,JB and PB,wich say that on those basses the PU is placed on 11'' regarding the 12th fret. What if an instrument has another measure? Wouldn't be more appropriate to measure the sweet spot from the bridge? And,in the end,one more question:are the "sweet spots" on different brands in the same place? I'm especially interested on Fodera's.....where do they established it?
