My drummer just contacted me to say he was possibly buying one, but didn't know anything much. I have come up with little info other than some pictures and a general idea that they were pretty good amps, and are collectible. But I can't find much out about the actual specs. I've gathered that it was a 70's tube amp, possibly 12" speaker. The Guess Who used Garnet amps, from what I know.Any more info or specs would be greatly appreciated. Thanks all.
