For the past few years the only basses ive owned and played are made from parts. I do this myself and i love it! Thing is all the basses ive done have had the screw holes and such for everything to be assembled. Replace bridges, pickguards, pickups, tuners, necks, etc. but always using existing screw holes. I want to get a body that has none existing to be more selective at what i want. What i need to know is where do i place the bridge measurement wise? And whether im screwing in pickguard, bridge, or tuners what is the best way to do so? Can i just tap a little then screw directly into the wood? Or do i need to pre-drill a smaller hole first?
