Yeah, sounds like you've got a pretty sweet setup... i'll buy a bass again one of these days. right now i am borrowing my buddies ibanez for some recording, and it sounds pretty good, but has too much "oomph" and not enough clarity. I'm not a great bassist by any means, but i know what i like and those musicmans are sweet. At a buddies gig a while back, he broke a string on his bass and the band that had just played tossed him up their bassists bass, which was a musicman, and it was night and day. Such a clearer, fuller and richer sound.
A buddy of mine has been playing his pedal steel thru an ampeg 1 x 15 bass amp lately (dunno the wattage, but its high) and it sounds clear as a bell, clean headroom for days. Ampegs are great amps for everything it would seem... every play one of their reverb rockets?
