Not something you see everyday. The 2nd gain knob added from the mod all the way to the right is pulled out to add the next gain stage. It has by far the lowest noise floor modded Marshall I’ve tried and one of the quietest high gain amps I’ve had in general. The power tubes are a pair of GE 6550A’s (Groove Tube labeled)
