Hey guys, new member here. So I've been talking with a guy that has a J5 for a steal of a price! The only reason I want it is to take on the project of making it a HHH configuration. Ok so, this guitar has 2 volume knobs. No tone. Would a on/off switch for only the middle bucker be the easiest way to add a middle pickup? Any other suggestions on wiring? If so, diagrams please! Thanks guys!!
