Robin, regarding your posts about moving the bridge around. I think in general you're just supposed to set the bridge so it's centered with the notches on the f-holes in the middle of the bridge, no?
That's where it's ened up
To Bruce's comments..
I did not try any other Basses, partly because it would be a day trip to stores that would have any decent ones, and partly because I didn't think I would have the first notion of what to play! That and I didn't want to spend a lot of $$ to try this experiment. If I didn't take to it, I didn't want to have a bunch invested..
As far as the playing differences, I learned to play the EB using DB fingerings.. that may be why it's easier than I thought it would be
As far as the first gig went..
The room has a low rumble around 130K.. I plugged into the Mesa and the bass just started to rumble on it's own (first time through a PA at loud volume), and I had to turn down to the point of being barely in the mix the first set. I played with it and the songs in the third set were better, but not so good.
Second night I brought my Hartke A-70 for the UB and set it on top of my Mesa and used a seperate channel on the board (I run sound from stage as well). The A-70 did much better

and the band LOVED it both visually and sound wise. Even SWMBO (She Who Must Be Obeyed) commented on how much the sound of an UB made a difference in the songs I'm playing it on.
I suspect that the pickup is part of the problem with the rumble. I'll be experimenting with that this week, and may end up with another pickup configuration before long.
I fully realize that this bass is a POS after spending some time with it (tuners are starting to stick, already), and it's not sounding like I think it should.. but it's fed my need to step into the DB world, and given me something to teeth on
A fellow Bassist and I will be giving each other lessons soon, He's in his 70's and wants to learn EB after playing UB for longer than I've been alive

And I'd like to pick up some tricks from him.
