So I recently bought an RGA8QM (pre-loaded with EMG 808X's and a tone pot!) in an eBay deal and when I received it, I saw that one of the string lock inserts was missing from the bridge. My question is, do I need to replace the insert with one specifically made for an Edge III, or will one from a Floyd Rose unit work? Normally I wouldn't have any problem with buying a block online, but getting one direct from Ibanez will run me $25 (including shipping) and I can't get one from ibanezrules because of the minimum purchase amount. Thanks in advance for any help and hopefully I posted this in the right section.
