My Bari-Tele in my siggy pic below is a GFS clearance body, which is Paulownia. Very soft.
I too, had to re-drill my neck mounting holes, but on the body. When I purchased it, I had to route for humbucker using my Stew Mac template.
I also had to re-route for the Tele bridge when I switched it from humbucker back to single coil when I installed the EMG Tele set in it. Mine was off too, so I couldn't just mount up the bridge.
Speaking of the bridge. GFS is not consistent in the drill pattern between their Tele Humbucker bridge and the Tele Single Coil bridge.
More specifically, between their parts:
C26 "Modern Style" Tele Upgrade bridge Stainless Steel Saddles chrome and
C04 Chrome Humbucker Bridge for Tele Guitars.
The outer 4 perimeter mounting screw holes don't align, nor do the 3 mounting screws under the saddles. Only the center mounting hole under the saddles does. Not necessarily relevant unless you're switching from one coil to 2 or vise versa as I did, but I thought it was worthy of mention.
I treated all of my holes with crazy glue after drilling them out one size smaller in order to get a good bite on the threads. The entire outer dimension is smaller, as you can likely see in this pic. I compensated by using a small brass plate that I got from Michael's to cover up any reveal from the sides. The Humbucker bridge rode right up to the edge where the buckskin is, maybe 1/16" of reveal. The SC bridge increases that gap significantly. I also added some chrome bobbin toppers to the EMG's just to keep the chrome flowing as well as the vintage motif aesthetically.
Most of the GFS pickups are quite nice, but you need to give special care to measurement details when using their bodies/necks.
