Got this amp a couple years ago from long and mcquade and its by far one of the best sounding amps I've played. It's a 100w head but can also be turned to half power mode. Tubes are all still good and ready to go.
Comes with the foot switch to change between channels and to turn reverb on and off.
For more info check out the link to long and mcquade I've provided below.
Asking $900 but open to reasonable offers.
