I've been using an older Trace Elliot AH250 head into an Eden D210XLT for some time now. I'm happy with it for home use and I was happy with it when I was playing with a band. I've recently been looking for my next band and I've met some guys that seem nice and the music seems interesting, so I'm thinking I'm going to try out. This band already has a their own bass rig at their rehearsal space. They've got an Ampeg SVT-4 and Ampeg cabinet (I'm assuming 410). I've never used Ampeg gear, so I had to look that up - but that looks like a heck of an amp head! I'd like to play the SVT, just to check the thing out, but I also don't want to come out and spend a bunch of time playing around with their amp head. I'm wondering if I should skip their amp and drag along my rig when I go to try out? The Trace is very easy to use and I know how to dial in my sounds that I use - The Ampeg head, while nice, would be unfamiliar and it looks to have a few more knobs, a different type of EQ, tubes in the preamp which is foreign to me, and I would expect the whole sound to be at least a little different. Can anybody tell me how easy it is to dial in a nice sound with this type of head? I want to do well when I go out to play with these guys, and I'm going to need all the help I can get I'm wondering if I should bring my amp just to make sure that I'm not screwing around trying to find a sound on an unfamiliar amp, or even worse - somehow doing damage to somebody else's expensive bass rig. I'm also curious as to which people prefer - Ampeg or Trace Elliot.
