Three 12AX7 tubes deliver the perfect blend of classic tube response and the timeless “Variable Q” equalizer design of the 800RB.

Motorized pots allow two independent presets to be recalled on the fly for gain, tone and volume changes.

Analog power amp and power supply deliver classic feel and 500 Watts of hard hitting punch.

Tube driven transformer balanced DI with level control, Pre/Post and Ground Lift switches to feed the house, Tuner output, footswitch  and FX Loop for connecting outboard accessories.  Two twist lock speaker connectors to ensure reliable and safe cabinet connections, and two common ¼ inch outputs.

Inherited from the 800RB, this unique tube design varies the EQ bandwidth to retain a musical response even at extreme settings.

The signal path for gain, EQ, contour and the DI are 100% tube driven, achieving classic tube performance with 300V plates.

Dual rail analog power amp and toroidal transformer provide the current required to control the speakers at high volume.

Heavy duty chassis, large toroidal transformer and double sided boards ensure stable performance under the most rigorous tour conditions.
