Sorry to hijack this thread, but there are so many of them regarding trem replacements that I didn't want to start another one.
I've got one of the first JEM555s with the plain white pickguard and the TRS-II. Since the wood has cracked on both sides near the trem anchors so badly that the force of the strings has pulled the trem area up for about two millimeters, I thought when getting this repaired I might as well swap the trem for a better one (interestingly, when I told my guitar tech
about the cracks he immediately assumed that it's a JEM, he says he gets that frequently, and not only on Korean ones; and mine, despite its age, hasn't been used a lot).
I prefer low profile trems, so after some reading I understand this pretty much limits my options to the Low Pro Edge
(which seems to be hard to find in gold finish, which would be my preferred choice, although the original one is cosmo black), the Edge Pro or the Floyd Rose Pro (all of them pretty expensive...).
So, as I have just read in this thread, the FRP is an easy swap. But what kind of routings would have to be made to fit the other two (especially the Edge Pro, being the least expensive and easy to come by)? As the wood below the trem has to be replaced anyway, increasing the cavity wouldn't be a problem. But I don't want to mess with any of the painted surface. Would that be necessary?
And, just to be sure, I'd need an R3 nut, right?
Thanks for any input, your forums have been very helpful already!
Edit: Just noticed there's also a Schaller low profile FR. How about that one?
