I received a MM Humbucker template from Guitar Parts Center, waiting on my next step. MDF board can be rather iffy. Looking for a top bearing router bit. 1/4 inch, a suggested 1/2 inch for the majority of the work, and a Forster Bit to hollow out. The bits will cost about $30.00 a piece. I've never routed before, and I want a nice route so I don't need a ring. I'd have to practice my routing, PRACTICE? Gotta guy will do it for $75.00. What to do? Meanwhile, looking at the PBG RC-4 wiring diagram, rather daunting. How much will change with the MM Humbucker? I'd like a Split coil option, but with a knob, instead of a tiny toggle. I'd have 5 knobs. Any suggestions?
