Variable Q tube Equalizer
Inherited from the 800RB, this unique tube design varies the EQ bandwidth to retain a musical response even at extreme settings.
High Voltage Tubes
The signal path for gain, EQ, contour and the DI are 100% tube driven, achieving classic tube performance with 300V plates.
Big Iron
Dual rail analog power amp and toroidal transformer provide the current required to control the speakers at high volume.
Rugged Construction
Heavy duty chassis, large toroidal transformer and double sided boards ensure stable performance under the most rigorous tour conditions.
