Classic Boogie ...the return of the Hun/Rev/Graph!
In the history and lore of the Boogie® Mark IIC+, the HRG holds a firm and lofty place. While 75-watt Simul-Class™ builds surpassed both the Super Sixty™ and 100-Watt models in number during the original mid-80s Mark IIC+ production lifecycle, the original Mark I “HRG” format – Hundred-Watt/Reverb/Graphic EQ, or Hun-Rev-Graph – was always classic Boogie.
With bold authority, maximum headroom, tight-tracking low end, and detailed clarity, the HRG became a favorite of those looking for immense clean headroom as well as a truly commanding Lead voice. As the years passed and styles evolved, the HRG’s aggressiveness for “Crunch” rhythm work earned it a revered place in heavy rock and metal as well.
A Mark IIC+ HRG has long been the model of choice for virtuoso guitarist John Petrucci throughout his career with Dream Theater and various solo projects. Hence, this 100-watt model provided the perfect platform for the Signature JP2C we partnered with John to create for his performance needs.
With one of the most expressive preamps of all time and the mightiest of power sections, the HRG puts an exclamation point on the Mark IIC+ sound that is as exciting as it is unequaled.
If your dream amp calls for total authority, knockout punch, and undeniable character, look no further than the mighty Mark IIC+ “HRG.”
