The Rivera KR7 Mick Thomson Signature 100 Watt Knucklehead designed in conjunction by Mick Thomson and Paul Rivera adjusted the frequencies in the midrange to give the amp more punch and bring more definition to the bottom-end. Mick also had the gain increased and "sweetened" the top-end to compliment his guitars. Mick wanted this amp to be flexible for all playing styles but specialize in aggressive, quick and defined riffs. Complimenting his signature amp, Mick Thomson chose the Celestion K100's in his K412T MT and K412B MT signature cabinets to increase the headroom for maximum attack with lower tuned guitars.
3 channels, with 3 completely different circuit topologies and sonic textures, enabled by 5 12AX7WA tubes, along with 2 different and discrete sets of equalization result in a wide range of easy to dial up delicious and rich sounds. Spanning massive gain and distortion tones, to sparkling crystal clean rhythm sounds, you can have it all with the KR7.
On the clean side of tones, Channel 1 has pull switches on its 3 band EQ, to expand the highs and lows, as well as being able to choose blackface or tweed mid tones. The master control features a power amp boost when pushed.
Channel 2 and 3 share the 3 band EQ and feature separate boosts. A "Scoop" is also shared and can be used for a thicker lead voicing-think Santana.
Dual Reverb controls allow you to adjust the lush Accutronics spring Reverb for channel 1 and Channel 2/3. The Focus control changes the damping of the speakers, to tighten or loosen the cone. The Presence control adds an additional high-end boost at the tail end of the amplifier, providing even more harmonics.
