I've had my 68 Telecaster I bought new in 68 and it came with the bigbsy on it. I don't have any tuning problems with it at all. Of course I don't dive bomb with it, I play a lot of Chet Atkins and Merle Travis style guitar. Its always worked for me and I don't break strings either. I also have a 84 bowling ball strat that has the trem on it and it also works fine and stays in tune. I also have a 92 G&L ASAT that has the fender trem on it and it stays in tune also. If you don't beat the guitar to death and use it the right way, go for it. You'll like it for sure. My Telecaster came with the bridge they used on the Jagwire and mustang guitars I believe, but you don't need anything special, no locking turner and special nut or what ever. Get the bigbsy kit made for it you'll be smiling, and no, you don't need 2 guitars at the job. With that said, I don't dive bomb or play that style of guitar. The other guys could be telling you right about the tuning problems, I don't know. I know it works for me.
