Mesa Boogie Mark II A Head 1979 Natural Oak + Cabinet

Serial number: 3302

Mesa Boogie Mark IIA Simul-Class head and cabinet in very good condition. 
This is a great sounding amp, very versatile - great cleans and incredible distortion. 

The Mark IIA is a powerful and bold sounding amp, with the Simul-Class option you can use full power or switch to Class A for earlier breakup or keep the volume down. 

The Mark IIA is credited as the first guitar amplifier with a tube-buffered effects loop. However, the loop was placed between two critical gain stages, and tended to overdrive some instrument level effects, and also caused volume pedals to act as remote gain controls for the lead mode. Mesa later implemented a mod that caused the effects loop to become more transparent, and smoothed out the lead channel, similar to the IIC+'s lead channel. More importantly, it marked the introduction of Mesa/Boogie's "Simul-Class" system, where two of the power tubes (always 6L6s) run in class AB pentode while the other two tubes (either 6L6s or EL34s) run in class A triode. In a simul-class amp, running all four tubes generates approximately 75 watts RMS of power; running only the class A tubes produces about 15 watts. Also available were non-simul-class Mark IIAs in both a 60 watt version and a 100 watt version that allowed shifting down to 60 watts by turning off a pair of power tubes. The Mark IIB's front control panel is identical to that of the IIA. The two input jacks on the front panel are marked "Input" and "Foot Switch." The front panels read Volume, Treble, Bass, Middle, Master, Lead Drive and Master. It has "Pull Bright" on the Volume, "Pull Shift" on the Treble, and "Pull Bright" on the Master. The Rear control panel was altered to accommodate the FX Send and Return jacks.

The cabinet is factory equipped with Electro Voice EVM12L speaker and when cranked loud, it can rip one's had off. A crazy beast!

At the same time it offers a noble, amazing cleans ant crunches when adjusted reasonably.

It's a fantastic gear, a lucky strike for collectors, but also a great tool for working musicians.

A real piece of history, not bo be ovelooked.

Custom made flight cases included.
