Just thought Id share my experience with you guys. As some of you know, i have my current sixer being worked on, so Ive been without a sixer for a while, but all i had laying around was my old Ibanez RG370 with that cheap ass Edge Pro II trem...
An lately ive been dyin to play a 6er, but hated how that trem felt, but i had my Edge III from my RG5EX1 lying around and i love that trem...
So i swapped them out, and strung her, tuned her, and she works just fine, once the post adjustment is finished, lol. Getting the springs on are a little awkward, but not to tough, and the trem works fine for what i use trems for (i fix em, like for this one, i used a normal old lighter).
Anyways, just thought id share, so if theres anyone out there in the same boat as me, you have options....
