Overview - Mesa/Boogie MARK VII Owner's Manual

OVERVIEW

Congratulations on your choice of the MARK VII, and Welcome to the MESA/Boogie Family!
The amplifier you have chosen traces its roots back to the pivotal moment in the dawn of the '70s when Randall
Smith happened upon the Holy Grail for electric guitar and created the first tube preamp with cascading gain
stages. This landmark discovery gave birth to high gain and, ultimately, the sound of modern guitar.
With this invention, for the first time ever, sustain (created by tube overdrive) was separated from power sec-
tion loudness, and a new solo voice with sustain like a horn was unveiled that could be used at any volume.
Before that, blues and rock guitarists had to turn their amplifiers all the way up to nearly full volume to achieve
the sustain they sought. This new development would set guitarists free from that limitation and usher in not
only a new era of amp performance but also a new era of music reshaped by this game-changing circuitry.
More than fifty years and countless iconic recordings later, the impact of those original Mark 1 Boogies and
subsequent Mark models that followed and spawned nearly all now-commonplace modern guitar amp features
have had more than their share of influence on popular music. Starting with Channel Switching and Performance
Modes on the MARK II-A, B, C, MARK IIIs, and IV, up through the MARK FIVE with fully independent Channels
and Multi-Watt™ Channel Assignable Power, each propelled the sound of guitar and popular music forward in
their own time and way.
Now the culmination of all that innovation resides in your new amplifier, the MARK VII. More packed with fea-
tures and Tone than even the milestone MARK FIVE, the MARK VII retains the best sounds of all these iconic
amplifiers and adds a new one. From the model we leapfrogged – the MARK SIX – which provided a good
working platform and proving ground, but ultimately, we'd surpassed, it was clear we had a MARK worth skip-
ping a generational moniker for.
