I looked at a Strat today and was a bit confused and itchy... In the tremolo cavity there is a factory router hole as under strat pickguards on top. The guitar is presented to be Am but I have my doubts about that and if even a real Fender. Anybody got deets on a router hole in the trem cavity? The hole is under the center spring and is pretty much like size as the holes under pickguard that will ID Mex body, etc... I even googled trem cavities images and saw zero pics with a router hole in back... Somebody give up da deets... edro.
