See if your local guitar store will let you A/B test a passive and an active bass at the same time using the same amp. That way you can hear any difference there may be between the basses. Too many times when we get to try basses out we are unable to compare them with our existing bass(es) with the same type amp. Nothing worse than buying a bass because you just love the sound and when you get it home your old bass sounded much better.
