This is an old amp with no name on it it says model-6000. It has an on off switch,speed,strength for tremolo foot switch input,tone, volume , and 2 instrument inputs. Looks like a sears brand to me I know the pictures are horrible this is what the tubes say. 1st from left to right 12au8,2nd japan 608 or 808,3rd 12at6 USA,4th crest man japan 605. Not worth anything I know just thought I'd see if anyone knows what it is. I think its a 1 or 2 watt amp cheap speaker an it breaks up about the time its loud enough to hear.
