The Marshall VM2266C 50 Watt 2 x 12" Combo is an all valve single channel amplifier with a choice of 2 dynamic ranges, both selectable by footswitch. The low range equates to the tonal shaping and performance you would come to expect from stock vintage Marshall amps. The high range adds an extra pre-amp valve into the signal path, facilitating those classic hard rock tones of the 70's. With the 2 'frequency selective' preamp volumes (Body and Detail) allowing you further flexibility for tonal shaping, the knowledge that the power amplifier is based heavily on the first Marshall amplifiers can rest assured the hardest fans of original Marshall design. Features: 4x ECC83 pre-amp valves, 2x KT66 power amp valves. Footswitch included.
