Im getting a Jackson RR24 and i want to know about active pickups and how long the battery will last...
Someone said about 3-4000 hrs, don't leave your guitar plugged in when you are not playing it. I am not positive though, I am in the same boat as you, buying my first ones.
Ibanez S520EX EMG 81/85
Ibanez RG350MP
Fender acoustic (Black)

Peavey Vypyr 15
Peavey 6505 212 combo
woah i thought they were like a special battery for an electric guitar,im fine with getting regular batteries then
