Out Of Stock
Up for sale, a 1979 Mesa Boogie Mark II 1x12” combo in exceptional condition and in perfect working order. This early example of the iconic, pioneering Mesa Boogie amp dates to the second year of production; it’s the first iteration of the Mk. II platform, predating the approval of Mesa Boogie’s patents for the revolutionary Mode Switching (channel switching) technology introduced with this amp.

Complete with the original Electro-Voice EVM-12L speaker, this Mark II delivers quintessential Mesa cleans and rich, focused overdrive, with a wide range of versatile, vital tones easily accessed via the deceptively simple control configuration. There’s a natural fatness and punch to the sound, engineered to complement just about any pickup you throw at it, and dialing up the higher gain settings yields a harmonically-complex, unrelenting distortion. The clean/gain channels can be toggled back and forth with an external footswitch (not included), a feature introduced via this very amp and now widely considered industry standard. Controls include Volume 1, Master 1, Lead Drive, and Lead Master knobs, with Pull Bright, Pull Shift, Gain Boost, Pull Lead, and Pull Bright (Lead) push/pull controls, as well as a three-band EQ. The Presence and Reverb controls are on the back panel, along with the Slave Level knob.

The circuit is virtually untouched, with original transformers manufactured by Schumacher, dating between the 40th week of 1977 and the 29th week of '78. The CTS pots have visible date codes from the 29th week of '77, and the chassis is hand-dated February, 1979. The tube complement comprises a pair of Mesa 6L6 power tubes, and modern valves in the preamp. The Electro-Voice EVM-12L is widely considered EV’s flagship speaker, famed for its dark, expressive sound and fantastic power handling, featuring a very rugged frame and original cone.

The original blonde tolex is well-kept with light wear on the enclosure edges, and the original wheat grillcloth is also present and similarly preserved. The faceplate graphics are pristine, and all of the original knobs are present. The nickel-plated lower corners exhibit modest patina, and the original casters are installed.
