I just bought this big old bass combo from my art teacher at school. The name on it says Hohner, but when i went to their web site, it said nothing about amps. It has a 15" Eminence Beta speaker which my teacher said was recently put in. I don't know how many watts. It has a volume, 3 tone dials, and a boost dial. It also has 3 inputs, marked bright, normal, and deep. My art teacher says it's all tube, but i'm not sure. It sounds alright, and i only paid $50 for it. Has anyone heard of these or know anything about them? Thanks.
