'll start by saying that being able to beat on a Brand new Shiny Fender Telecaster was the trill of a life time. I personally have no love for any Fender newer than 20 years. I find their quality to be sub par and their components to be less than top shelf. However, a buddy of mine asked me to take his 1950's Telecaster reissue and make it look like it was from the 1950's.
I started with a poorly (factory) set up blond see through Ash Telecaster that came with the Fender/Bigsby tail piece and bridge. The owner wanted the paint to be abused (but recognizable) and he wanted three humbuckers in it. He primarily plays blues so he wanted this to be a tone machine. The guitar in it's original state had very little tone what so ever.
First, I replaced the single ply black pickguard with a three ply B/W/B cut to fit two humbuckers and then retrofit it into the existing holes. I then abused the existing hardware and paint. I removed some on the front and back down to the wood and removed some of the nitro so the owner, when playing it will cause it to age faster but in a natural way. I tried to keep the chipping on the edges and maintain a natural wear pattern with the paint. I took the shine off of every part of the guitar, including the neck.
I sanded, dinged, scratched and did everything I could to get a pitted, aged chrome look to the hardware. The pictures really don't show a lot of the dings and chips in the body but it turned out nicely.
I replaced those crappy Fender mini pots with full sized switchcraft 500K pots and added a mini switch to control the middle pickup. The 3 way switch functions as usual an you can kick in the middle pickup with the mini. I also used a Sprague Drop orange cap for added tone. The neck and middle pickup are Golden age pickups and the bridge is a 59' from SD.
Needless to say the tonal response is huge. With the bridge pickup on only you still get a telecaster sound (with a bit more beef) and with the bridge and middle on you get an awesome blues tone. After that you get into the Les Paul range of tones.
I have to say that I'm personally not into relic guitars as I like to see them age over time but this was fun and was a pretty cool learning experience. I'm sure I could improve my process and produce a better (looking) guitar but the major focus was on tonal improvement which was not super easy given the crappy bridge (and the fact it's a Fender)
