I have a line a gently used SD Vintage Stack Telecaster p'up set for $60. I'm seriously thinking of doing a transplant into my Squier Bullet. My question is: will I need to enlarge the p'up cavity in the guitar, or will these SDs drop in? I'm probably going to do a 4 position switch as well and upgrade the electronics(pots, etc.) Any suggestions? Thanks for your time.
