A Little History...Congratulations on your choice of the 

HEARTBREAKER

  as your amplifier!  Its fine all-tube heritage is apparent

in each soulful note you play, but you may not be aware that this amplifier was created as the 25th anniversary tribute to the amp that
put 

Mesa/Boogie

 on the map and changed guitar amplification forever...the 

Boogie

.

The 

Mark I Boogie

 burst on the scene in late 1970 as the first amplifier ever to contain a high gain pre-amplifier that could be

overdriven at any output volume. By ingeniously using a cascading series of pre-amp stages, Randall Smith brought to life the (until
then) latent potential of the 12AX7 and changed the sound of electric guitar. No longer would the saxophone be the most likely
instrument to grab the solo spotlight...now guitar had a singing voice! With its liquid sustain and bold authority, the early 

Mark I

immediately won the hearts of the worlds’ top players and was soon an international smash hit. Overwhelmed by orders for this
compact, high performance 1x12 giant killer, Randall made plans to leave the store he had co-founded, (Prune Music,) where he had
been modifying and repairing amps (for the stars of the Bay Area’s music scene) and move the operation into a converted shack
behind his house.

In this shack in the mountains north of San Francisco, every part of these first 

Boogies

 were made by hand! The chassis was formed,

circuit boards were etched, front panels were silk screened and the first exotic hardwood and rare snakeskin cabinets were made...all
with relentless attention to detail. 

Mesa Engineering

 was now in full swing with world wide acclaim. High gain was born back then

and seemed to be here to stay, as proven when the 

Mark II’s

 introduced the world to channel switching in late ’78. The next

important development came in 1986 when 

Mesa

 pioneered the first Tri-Modal footswitchable amplifier, the 

Mark III

. The rest of the

amplifier world soon followed suit.

Now, the

 Mark IV’s

 offer fully expanded footswitchability...and high gain, multi mode, channel switching amps are everywhere. The

many innovations (seen for the first time) included on these early 

Mark I’s 

have since become standard features on virtually all major

brand amplifiers of today. All these modern amps have a common ancestor in the original 

Boogie.

..the missing link between vintage

(one sound) and modern high gain, footswitching (multi sound) amplifiers.

The 

HEARTBREAKER

 assembles all these early innovations (along with many more recent ones) and showcases them in a 2

channel, 5 mode footswitching package that pays ultimate tribute to the soulful voice of these vintage 

Mark I Boogies

. Enough

history for now...we thought you might find your new 

HEARTBREAKERS

’ lineage interesting - and possibly give you a sense of

pride knowing that its bloodline figures prominently into amplifier history.
