I just got some blackouts yesterday and the guitar I'm putting them into is a Ibanez S Series in the H-S-H config...I dont want to leave that single coil as just a dummy pup so i was considering getting a blackout single coil (the AS-1) to to add to the guitar...can a 9v battery run three pickups? Reason I ask is because the S series is a thin body and I dont think two batteries are going to fit into the cavity. Anyone ran three actives off a single battery before? Severely decreased battery life? Funniest part is I probably wont even use it.
