I've come to learn I'm bad at any sort of modding/customizing or anything like that.
To customize it would mean taking an empty body and rebuilding it from scratch. That'd be the best way to do it.
Somewhere along the line I'm pretty sure the wiring is a little iffy, so you'd need to rip it all out and just put in fresh stuff. Some better pickups and you'd be set.
Wouldn't be great, but it'd be better than it is now.
