Over the last year or so I have been selling off the majority of my active basses. Everyone seems to mention "crisp" or "bright", the fact is we play BASS! Correct me if I am wrong, but if you want crisp and bright play the guitar!
Personally, I use flat wounds on every bass I have. My main basses are Jazz and P-Basses, both modern and vintage. I run full volume and tone on the bass and roll off most of the mids and highs on the amp. Again, I play bass....not only do I want the crowd to hear me, I want them to feel the thunder of the low end!
Now I am stepping off of the soapbox; when it comes to it, simplicity is key...no batteries, no worries of failure, no messing around with a ton of volume and tone controls...it is just so much easier with a passive bass. The only time I need to make any adjustments is when I change basses. If I go from one of my vintage basses to a newer one it usually requires me turning the amp volume down a bit (or vice versa).
Call me lazy, but the least amount of worries I have the better it is for me.
