Thank you everyone who recommended faction guitars to me, I now have a nice switchplate for my project!
My next (and possibly stupid) question is: has anyone used allparts jaguar control plates? Are they the same size and shape as the fender ones? I need the 2 main control plates to fit as well as possible with a pickguard cut from a fender modern player template. I'm in the UK so Allparts is tempting as genuine fender parts all seem to live in the US and the shipping is crazy!
