OK, let me clarify a few things...
It's not that the soundman didn't want our guitarist to turn up "as loud as he wanted." It's that he didn't want him to turn up AT ALL. He was on 1/2 of 1. Even without the drums going, I could barely hear him from the other side of the stage. Tube amps have to be turned up a little ways to get any sort of attack and presence, otherwise they sound spongey and terrible. That is what was happening. Granted, a JCM800 is more amp than was really necessary for the situation, but there was no reason to make him turn it down THAT far.
I know that there is a difference between front of house sound and stage sound. I also know that if your amp sounds terrible before you mic it, then it will sound terrible when you DO mic it. I am an A/V tech by trade, and I know how these things work.
I also know that it IS possible to carry a small to medium sized room without PA support for the amps. I've done it several times, and as long as everyone realizes that they can't just turn up as loud as they want, it can sound pretty good.
The link in my sig is my old band, not the new one. The new band is poppier and not nearly as heavy.
It wasn't just our band that sounded bad with the sound guy. We were there when the headliner (The Wedding) was soundchecking, and he made them sound terrible too. Also, it wasn't just me that was frustrated with how the situation was going. EVERYONE in the room during the soundcheck time was commenting on how bad it was sounding, including people that weren't even IN bands, and the promoter.
I am also not shifting the blame for anything. As I said, once we were able to get the kinks worked out, the show went really well and the kids that were there dug it. My point was that it was frustrating working with someone who seemed to have VERY little knowledge of how to effectively run sound. I've dealt with some less than stellar soundguys before, but nobody as bad as this.
