Well. i (think, most probly) am getting a spector. its got a active tone curcit, but not active pickups. 9V. I know i would have to add another battery for the 18V electronics. How on earth would i do this? should i not touch and let someone else do it? tell me anyway, even if you think i should take it to someone. Do i have to cut another hole in the bass? gosh i hope not. So, how would i add another battery?
