This clip demonstrates the tight, punchy and immediate response of the gain available in the MK IIC+ Mode of the Mark Five 25. The gain layering in this mode sticks tightly to your attack, splitting the difference between the gut-kick punch of a dry crunch mode and the lush saturation of one of the most renowned cascading gain sounds in rock history - the Mark IIC+. The EL-84s add their own bounce, bite and snarling personality as the gain goes up, especially when in the lower 10 watt mode.
Recorded with the Bridge Position Humbucker of a Gibson Firebird through the MKIIC+ Mode of Ch. 2 into two 1x12 Mini Rectifier cabinets loaded with Celestion Vintage 30 speakers. Recorded with a Shure SM57, Shure KSM 313 and the Mark Five: 25 on-board CabClone. Mixed with varying levels of the mics and CabClone for each clip and mastered for optimized output.
