You think so? I personally think almost everything matters, though to what degree can vary greatly. Pickups are definately at the top, but I think electronics, wood and overall resonance (which is affected by lots of things itself) all have a huge impact personally. I dont think what brand of strings you use or the angle of your tail peice and posistion of your knobs matter all that much D:
As long as you have a good base, thats a winning strategy.I am all about swapping PUs til the guitar/amp/setup sounds good. I have done it so many times I know it works.
But then again, I play LOUD... :-)
