I got a Japanese Jazzmaster not long ago, and the trem arm creaks unless I just barely push it down. I tried rescrewing the spring under there, but that only worked for a very short time, and I lubricated it with WD-40 (don't have graphite) but that didn't help for very long either. The trem arm doesn't lock into place or anything either, just slides in and out. If I got an American trem thing would that fit onto my Japanese Jazzmaster?
Also, are there any locking tuners that I could put in without having to widen the pegholes or modify anything, or they just not worth it?
Thanks a lot.
