Thanks guys, I appreciate it!
Geni, I definitely plan on running my direct out from the UL502 to every PA I get the chance on. I'm just concerned that when a monitor isn't available to me, that I will just get buried.
This is all me just being paranoid, and I know that. I'm sure I will be much happier than expected when I start gigging with this new band, but I just wanted to put my concerns out there. Again, thanks for all your help everybody.
I think you are just being paranoid. I play in a real loud R+B group with keys and "dueling guitarists", as the drummer and I call them. (Damn good guitarists, BTW.) My T212 is more than enough for inside medium club work. I do, however, have a ton of headroom (Crown XTi2000).
And the monitor doesn't have to be just for you. Just a little in the ones meant for vocals/horns/keys/drummer make a difference is how the bass sounds on stage. Again, just a little. It will beef up the bottom end on stage so your rig can be thinned out and cut through.
