Okay so I've had my new Ibanez RGA72 with trem for about a month now and I really wanna replace the stock active in the bridge with an EMG 81. Is that even possible without tons and tons of extra work? I know that EMGs operate on 9v batteries whereas these Ibanez ones run off 2 AA's. Will I have to replace the battery compartment and everything? Any help would be greatly appreciated
