hi im gonna build a guitar soon,(everything except the neck and head stock etc.
the only thing i dont understand is routing, im unsure of what shapes and where i should be routing out. its going to be a super strat with a humbucker and two single coils, and 3 knobs, and a tremolo armed bridge.
any pics/ diagrams.

You can buy a template off of guitarbuildingtemplates . com and they should have a strat model you're looking for. Also, look for the guitar building book by Melvyn Hiscock, which has template sizes for pickups and tremolos in the back of the book.

I'm sure if you look around on the internet enough, you'll find proper routing depths.
