I used to have some ridiculous bass gear... had a Rickenbacker 4003 JG, Lakland 5 string, Matt Pulcinella Guitars (MPG) Level 5, and some others that i'm forgetting.
i used to have a sweet bass rig too, a BBE BMAX-T tube preamp running to a QSC PLX2402 power amp (24lbs!), running either an Eden D410T or an Ampeg SVT-1540HE (4x10 + 1x15 in an 8x10 cab), also had an Ampeg SVT-3Pro for a while...
I miss it.
Now I just rock a Essex 60's Jazz Reissue... Essex (or SX) makes cheap chinese fender knockoffs, but they are of astounding quality. I got an excellent one - vintage white, ashtray pickup / bridge covers, etc. Mine plays like fucking butter. I don't have an amp anymore
