Re: Strat wiring Idea
Already did this by routing out the side of a cheap strat body, adjacent to the pot cavity and fitting up different pickguards with different selection of pups, same tone controls and capacitors, 2 jacks, and one 5-way switch.
The jacks are wired with one going to the amp and the other going to the normal stratocaster jack, which is now wired up only to the bridge (String Ground)
Then you use a short right angle jack to plug into the extra jack and go to the normal jack - thus completing your string ground and the other jack (On the pickguard) goes to the amp.
I used the 11 screw setup pick guard and it would have been eisier using less screws. The whole assembly slides out the routed out side of the body.
The benefit of this setup is that you are using the same guitar body, neck, bridge, tuning machines, strings, setup, and amp - and can check out which pup combination works best for you.
I settled in on Seymour Duncans and Fralins
