This is a vintage 1975 Seamoon Moon 45solid state guitar amp. Best known for their Funk Machine pedal, Seamoon was a small company based in Berkeley, California that eventually became A/DA in 1976. This amp was one of the last designs before the rebrand/rebirth of the company. It's an amazing sounding transistor amplifier that can get loud. Cranking the gain and trimming it back with the master volume lets it grit up in a pleasing, tubey manner . Its back panel is on hinges for open or closed operations. We're assuming it pushes about 45 Watts through a 12" Celestion G12T-75. It's in exceptionally good condition and seemingly pretty rare. Would probably sound great with bass, too!
