The Mesa/Boogie Mark Five: 35 tube amp combo delivers legendary Mesa tone from its Mark Series preamp and proprietary Dyna-watt, 4 x EL84 output section. Pushing the EL84 power tubes lets you dial in everything from sweet cleans to roaring leads. The two independent Solo controls allow you to footswitch a preset boost. And the Mesa/Boogie Mark Five: 35's built-in CabClone speaker-emulated output, with closed-back, open-back, and vintage voices, completes this amazing gigging and recording tube amplifier.
