Mesa Boogie 1984 Mark IIC+ Rig - Black Bronco / Black Grille

There are amplifiers… and then there are relics of sonic mythology. This is the latter.

Offered here is a true, factory-original Mesa/Boogie Mark IIC+, completed in December of 1984, ordered new as the coveted DRG package—Simul-Class, 5-band Graphic EQ, and Reverb—with zero later modifications. No retrofits. No conversions. No compromises. This is the Holy Grail of tone, exactly as Randall Smith and Mesa intended.

This particular Mark IIC+ is a one-owner amp, and it shows. In fact, it is the cleanest example we have ever encountered, especially remarkable given its 42 years of age. From day one, this amplifier was not merely owned—it was cherished.

The original owner was a young player in 1984 who saved diligently to acquire what was then—and remains today—the ultimate guitar amplifier. Ordered over the phone with Doug West, this Mark IIC+ represented years of ambition, dedication, and musical aspiration. Once it arrived, it became a lifelong companion—carefully used, meticulously maintained, and respectfully preserved. This was never a disposable piece of gear; it was a dream realized, and it was treated as such for decades.

Stored properly, serviced responsibly, and never abused, this amp lived a protected life—always valued, always respected, always loved.

• Factory-original Mark IIC+

• DRG package (Simul-Class, Graphic EQ, Reverb)

• Serial #: 13852

• Completed December 1984

• Original American STR-415 power tubes

• Original American preamp tubes still installed

• Exceptionally clean chassis, faceplate, and cosmetics

Included are two matching 1x12 open-back cabinets, ordered at the same time as the head and loaded with the legendary EV EVM-12L Black Shadow speakers—the speakers that define punch, authority, and infinite headroom. This is the full, period-correct rig as it left Mesa in the mid-’80s.

From John Petrucci to Prince, Steve Lukather, Vivian Campbell, Brad Gillis, Metallica, and countless elite studio players—this is the amplifier that forged records, shaped genres, and defined the sound of the cosmic gunslinger. Crushing gain, liquid sustain, piano-like low end, and articulate highs that cut through any mix without ever turning harsh.

Simply put:
This thing is crushing on tone.

In December 2025, this amp was fully gone through by the legendary Mike Bendinelli, one of the most respected Mesa/Boogie technicians in history. This service was especially significant, as it was one of the final amplifiers Mike worked on before his well-earned retirement.

• Fully inspected and cleaned

• Properly recapped with high-grade German F&T capacitors, per Mike’s recommendation

• Brought to optimal operating condition with longevity in mind

This Mark IIC+ is now fully mission-ready, with years of interstellar travel ahead.

Included with the amp:

• Original Mesa Boogie slipcovers

• Original 1984 price list and options sheet

• Original owner’s manual

• Original 1984 Mesa Boogie catalog

This is not just an amplifier—it is a time capsule.

The Mesa/Boogie Mark IIC+ is widely regarded as the rarest and most sought-after amplifier Mesa ever produced. Factory-original examples in this condition—one owner, documented, unmodified, and complete—simply do not surface.

Pieces like this do not show up every day.
In truth, they almost never do.

No serious collection is complete without this icon.
Strap in, hold on, and prepare for liftoff.
