This is an original GT Electronics Solo amp (not the later Soul-O version).
It is 75 watts and can run in three different modes, A, AB or Gnarly.
This amp has a beautiful clean tone and some great distortion tones.
The amp has some of the front panel markings rubbed off and there is some slight rust on the chrome. It has had a full service and is in full working order. Comes with the original footswitch.
