This is a rare 122RV (reverb) model we found in a funeral home. New Tubes, new capacitors / resistors as needed motors oiled and tweaked. They will never make this model again. On board reverb speaks thru 6x9 speaker on side of cabinet. The big thing that makes this different is that it takes the output of the amp and picks off the signal for the reverb So whether its clean or knarly it reverbs that signal thru its own amplifier. The finish is immaculate.
