For starters, the input caps can go - you aren't feeding in anything with a DC voltage component, so you don't need that 'protection'. Otherwise, you could eliminate a few parts. Sensitivity versus noise may become an issue here, I dunno for sure. that's just disguising the problem, not curing it.)įurther, you do understand that that circuit was/is designed for line level signals, not guitar pickup levels. (And those grommets being used as dampers. I think that mounting one of them inside a guitar just may have undesired repercussions.
