The Mesa/Boogie Mark IIC+ is the ultimate reissue of a true legend—an amp that defined an era and earned its place in rock history. Originally launched as the evolution of the groundbreaking Mark II, the IIC+ was the third generation in the iconic Boogie lineup and the final version before the introduction of the Mark III. Revered for its incredible tone, versatility, and feel, the Mark IIC+ remains one of the most sought-after guitar amps of all time—and now, it’s back.

Staying true to the vintage design, the IIC+ features a single-channel, dual-mode layout with dedicated Rhythm (clean) and Lead (overdrive) preamps. Each mode has its own interactive Gain and Volume controls for precise tone shaping, while a shared 3-band EQ handles overall voicing. Want to fine-tune your sound even further? Engage the Mode-specific PULL SHIFT functions or dive into the powerful 5-Band Graphic EQ for precise tonal sculpting that’s fast, musical, and deeply customizable.

Around the back, you’ll find modern features that make the IIC+ as gig- and studio-ready today as it was in the ‘80s. Global Presence and Reverb controls, a buffered serial effects loop, and a power selector that lets you choose between 75 watts of Simul-Class power or 25 watts of Class A for smoother breakup at lower volumes. The Slave Output taps the full sound of the amp—preamp and power section—for seamless integration with IR loaders, wet/dry rigs, or studio processors.

Built with meticulous attention to detail and modern compliance standards, the new Mark IIC+ isn’t just a tribute—it’s a resurrection. Whether you're chasing the sound of your favorite guitar heroes, avoiding the gamble of aging vintage units, or just want uncompromising tone in a timeless format, the IIC+ is ready to deliver. Be warned: once you experience its searing articulation, dynamic response, and raw musicality, no other amp may ever feel the same.
