I just bought my first bass a couple of months ago. It's a yamaha RBX760 series and it apparently has active pickups. I'm not really sure what this means other than I have to keep a pretty fresh battery in my guitar if I want it to sound good. I've noticed that I get some distortion when the battery starts dying. Is there some benefit to having active pickups over passive ones? All I know is that I'm going through a lot of batteries. Now I just take the battery out of the guitar when I'm not playing it. It's not really that big of a deal but it is kind of a pain in the ass.
