I have one that I use with headphones for practice in my music room. It distorts at a low level, so I turn the volume all the way up and use the gain control for volume. Still distorts somewhat if you push it, but the tone is very good at mid level. I tried it with one and then with two 2x10 cabs, but it's not for rock IMHO, but probably fine for church, small bar, etc.. I bought an old Eden WT550 for playing out, fantastic amp & awesome sound through those two cabs.
I'm seeing these amps at bars and with PA support they work great for rock.
