Take a look at Pignose. You're going to get a lot of people telling you that you've gotta have 50 or 100 Watts to be heard, but it ain't so.

Lately, I've been feeding my Peavey Rock Master preamp into the power section of an old tube radio I picked up at a flea market. It puts out maybe 4 Watts. Its plenty loud for practice, and if I use it on stage, I'll just mic it into the PA. And it sounds BOSS!

I finally get some time off between Christmas and New Year's Day, so I'm going to do some work on the WeeBeastie 5 Watt amp I've been trying to get around to for a couple of months now. I'll post the results in Tech Talk.
