One of the fun things about building electric guitars is wiring them up. Factory wiring tends to be simple, minimizing the amount of fussy handwork required. Many manufacturers keep strictly to 'classic' designs, seldom if ever changing anything. These designs are generally simplistic, often crude or even stupid, and sometimes outright flawed. There is no need for you to do this. I don't. Here are some of the things I have done over the years. I don't claim to have invented any of this, although some of these schematics I have never seen anywhere else, and had to derive them myself.
I've been thinking about what I want to do luthiery-wise from here on out, and I think that apart from the cool Radiata glue-ups, I am going to do mainly plywood-core Danelectro-style bodies with Tolex side bindings. I want to avoid bothersome complications like three-dimensional paint jobs. If it's not enjoyable, then why bother?
