The Mark IIC+ is pure “vintage Boogie®” and based on the original Mark II (now called the Mark II-A) design, the world’s first “Dual Mode” amplifier containing independent performance modes dedicated to clean and overdrive sounds. The IIC+ model represents the 3rd generation of that game-changing single channel/dual mode layout and includes all the refinements made to that original format over its nearly five influential years.

The IIC+’s single row of controls is shared by its two modes (preamps), one for Rhythm (clean) and one for Lead (overdrive). Independent, though still interactive, sets of gain and volume controls help optimize each gain structure while shared Tone controls handle the broad stroke voicing. Fine-tuning of the sounds is accomplished by the PULL SHIFT voicing features – some Mode specific – fitted to the simple controls and further shaping via the on-board 5-Band Graphic EQ. Though the “Q” of the individual Bands (Slider Pot frequencies) is fairly wide around their Center Points, they provide a surprising degree of surgical-level sculpting quickly and musically.

This model is from Line 6's Agoura modeling technology, which combines the different inputs and channels of the physical amp into a single model.
