So I realize it's not an ibanez but I figure the base if knowledgeable herr is quite good and the other forums aren't great. I'm probably going to buy a Peavey Destiny. It has a Kahler spyder double locking trem. The term still could be good but these older guitars are worn sometimes. I'd like the option of a double locking replacement. Is there one? Or, will one work (FR) if you do routing and such?
