This clip compares the two clean modes on the Mark Five 25, CLEAN and FAT. The riff also showcases the subtle purring overdrive potential of the FAT Mode when pushed into slight clip with the neck position pickup, shown toward the end of the clip.
Both clean modes deliver the signature Boogie sparkling clean as well as offering amazing pushed clean and overdrive possibilities as the Gain control is raised above the halfway point. Combined with the Mid Boost feature of the Mark Five 25, authentic traditional Blues sounds abound in addition to the crisp, accurate clean sounds you would expect from Mesa.
Recorded with the split Bridge+Middle position then the Neck position pickup of a Tom Anderson Drop Top Classic through the CLEAN then FAT mode of Ch. 1 into two 1x12 Thiele cabs loaded with Celestion C90 speakers. Recorded with a Shure SM 57, 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.
