First Bass I've owned with Active Electronics. Ibanez SR 405 5 stringer, that I love by the way. Original battery has been in it 14 months. Picked it up at lunch to get my lunch time bass fix, and thought the speaker was blown in my amp. Exactly what it sounded like. Then realized that I did something I never do, I had left the chord plugged into the axe since yesterday. New battery fixed her right up. Needless to say, I always assumed that when it went down, that I would still have the sound of a passive Bass. Thus I never worried much about it dieing while gigging. That obviously isn't the case. I now have a new spare battery in my gig bag.
