A great vintage solid state amp from Hudson originally made in Japan with three instrument jacks, volume knob and tone knob. The main issue with this unit is that the tow knob and its selector is falling loose inside of the amp. due to this it can't be turned on through the knob but instead you would have to open it and change the tone knob switch to on. also, it is unknown if this unit can produce sound through the Jack.
