Had the first full band practice last night with my new (old) Zeta Crossover EUB! It sounded great, sat in the mix perfect and I really just had to roll of some treble on the amp when switching between it and my P bass. I traded an older strat & MIM bass for it. Supposedly its one of a couple prototypes made. Either way it sounds and plays great (34" scale as opposed to standard DB scale), and I'd much rather travel with this than a full sized upright since I own the p.a. too. Sorry for the crappy cell phone pic, if I get a chance I'll post some sound clips if anyone is interested.
