So - I've been playing a lot lately - and my Ibanez bass - as much as I love her - has been eating 9V batteries like a bad case of the munchies. It occurs to me last night - Why don't bass guitars have an AC adapter? I run a wire to my amp - why not have another wire for power? Off I go to the local electronic surplus store, come back with some wire, an adapter, a cool blue LED, and a few other components. Long story short - I got it to work - and work REALLY well. In fact, I noticed a more consistent signal out of the bass. Anybody else seen this or done this? Or am I just scratching my head wondering why no one else does this?
