I like the trem I have in one of the illegal Strats I made. The guitar is very resonant and the trem actually stays in tune.
That trem is a Callaham block with Fender "Pat. Pending" saddles and I have no idea where the rest of the parts came from but it works. Too bad the guitar doesn't have some other issues.
I also liked the trem in my old Jazzmaster. Too bad I sold it. :(
Good choice on the Callaham, i've heard they are very nice! Been thinking about getting one for my Squier Affinity strat (first guitar) but i'm unsure on the width for that particular guitar...
I'd drop them an email; they are usually pretty good about answering questions.
