Jazzyvee,
How's your luck been with the backlines lately? I did a *big* local show on July 4th with a bunch of other bands (Confederate Railroad was the headliner - I think they had one hit 10 or 20 years ago) and the backline had a decent bass amp, but discovered AFTER our set that they hadn't plugged it into the system. THAT explained the spotty bass mix out front all day! When I pointed out that it wasn't plumbed into the system (and I was nice about it), the stage tech just said whatever... That's my rant for the day, and hope you're having better luck..
John
