my bsb and rg550 are blocked...i hate floating trems with a passion most days.
for the days i don't hate the floating trem approach, i play my 770dx, which is set to float...though, every time it goes out of tune/restring or i want to drop tune or tune down, i swear, i'm going to block it!!!!!
i played a shit ton of jems before i settled on the bsb. what set it apart for me was exactly what you guys mentioned....least "signaturish" of all of them....and it just has this fuckin vibe i can't explain..so i ordered one without even playing it to boot!!!!!....it almost looks homemade and when i gigged with it, i used to always get inquiries and compliments on mine.
the bsb has a naked neck too, which makes it just a true pleasure to wank away on....it's so fucking fast and smooth, it's almost like cheating at the guitar...it prompted me to steel wool all my Lesters and i even sanded one completely down..i love that bare wood neck.
if you want a jem you can play the fuck out of and find relatively cheap, get a bsb in good shape....or a 777DY with pyramids in the maple neck

. watch for those neck joint cracks though on the finished jems...i swear, EVERY one i played had at least a hairline crack and they were pretty much factory direct. something about the humidity/change of seasons really affects those basswood bodies that are finished, at least in this area.
anyways /hijack over.
