I owned the avt50 and the 1960a cab and honestly while I liked the tone of the 50 when I first got it, i hate it now. Sixways said its half solid state half tube, thats not really true. Most tube heads have more than one tube preamp and then several power tubes. This things comes with one 12ax7 and thats it. I had a band in a few months ago with the cheapo marshall solid state everyone has and I honestly liked the tone better, eventhough they both suck really. I've also had problems with the avt50 making ridiculously loud grinding noises that just seem to come and go as they please and let me tell you that can really screw up a recording. I hated the act50 so much I sold it just a couple days ago. Don't let the fact it has a tube convince you its gonna have tube character cause it won't.
