I started playing electric bass in the summer of '74 with a fretless Fender P-bass (it's name is Thor just in case anyone was wondering

). I've played passive basses ever since. Now, I've been looking for a 5 string bass for a long, long time. A lot of these basses had active pickups or active electronics and some of them might even have had both. Well, I just bought the 5 string love of my life...a Dingwall (grin, of course) Afterburner I (passive, natch).
The reason I've stayed with passive basses is two fold...first and foremost is that if I need to juice up my sound I can always add an outboard pre-amp. In my opinion why clutter up the bass with extra electronics that can go wrong during a performance? Secondly, and, in retrospect maybe more important the number one, your sound is your sound. I've noticed, as I've tried out different basses over the years, that I sound like me, no matter what the electronics in the bass are. I can sound more modern or more...shall we say 60's Fender like...but it's still me. And once I realized that I could really control the changes in era at the amp...I decided that my bass should be simple and direct. Now I know that this is not the right approach for everyone...and I'm not trying to convert anyone to my style of buying a bass...but I agree with Jaco that the sound is in your hands and everything else is, well, maybe not irrelevant, but not going to get you hired or fired as a bass player.
By the way...my new Dingwall (it's name is Odin by the way...grin) just made all my other basses back up instruments...Thanks Sheldon, I'm in love again.
