Mesa Boogie Mark IIC+ HRG: Iconic 100W Amplifier Head

Within the history of the Mesa Boogie Mark IIC+, the HRG edition occupies a particularly important place. During the mid 1980s, most production leaned toward the 75-watt Simul-Class models, which outnumbered both the Super Sixty and the 100-watt versions. However, the original Mark I HRG format, standing for Hundred Watt with Reverb and Graphic EQ, remained a definitive expression of the classic Boogie sound. Now, this iconic amplifier is back and once again available through Mesa Boogie, giving players the chance to experience the unmistakable magic of the HRG in the modern era.

If you missed out on the original launch of the Mark IIC+, this is a great on to check out and get your hands one. With the increased power of this amp, you're going to love it.

The Mark IIC+ HRG earned its reputation for bold authority, immense headroom, and a low end that stays tight and defined even at high volumes. Its clarity and dynamic range made it a top choice for players who needed sparkling cleans with plenty of room to breathe, while its commanding lead voice offered the kind of sustain and articulation that set a new standard for high-gain performance. As heavier styles gained momentum, the HRGs natural crunch character also secured it a lasting place in the worlds of hard rock and metal.

Few players have showcased the power of the Mark IIC+ HRG as prominently as John Petrucci, who relied on it throughout his career with Dream Theater and beyond. This legendary 100-watt platform even served as the foundation for the JP2C, the signature model Mesa Boogie developed in partnership with John to meet his exacting performance needs.

The Mark IIC+ HRG features a streamlined control interface with a single row of controls for its Rhythm (clean) and Lead (overdrive) modes. The interactive gain and volume controls allow players to customise each mode's gain structure, while the shared tone controls adjust overall voicing. The amp is equipped with "PULL features for further tonal control and a 5-Band Graphic EQ that enables precise sound sculpting. This EQ's wide-range sliders can shape frequencies with surprising precision, adding adaptability to any performance setting.

On the rear panel, the IIC+ HRG offers a range of practical features that make it a powerful tool on stage or in the studio. The global PRESENCE and REVERB controls are centrally positioned for easy access. The amp's series, Tube Driven Effects Loop provides seamless integration for time-based effects, while a Power Select switch lets players choose between full 100-watt power for maximum headroom or 60-watt power for smoother clipping and reduced volume. Multiple speaker outputs allow flexible cabinet connections.

For those who seek an iconic sound without the need for an overly complex interface, the Mark IIC+ HRG is an ideal choice.

With one of the most expressive preamps ever created paired with an authoritative power section, the HRG stands as a definitive statement in the Mark IIC+ lineage. Now reintroduced by Mesa Boogie, this legendary amplifier once again gives players the chance to experience its unmatched power, precision, and musicality.
