This Rivera KR7 is Mick Thomson's sonic signature distilled into a head – it’s built for aggressive, modern metal. The EL34s give it that classic British bite, while the tweaked mids cut through the mix like a chainsaw. If you're a high-gain player who wants serious power and control, this is a compelling choice.

Each channel offers distinct gain levels and EQ characteristics; Channel 1 is the cleanest, Channel 2 is a medium-gain rhythm tone, and Channel 3 is full-on high-gain mayhem.
No, the Head Master MIDI pedal primarily manages channel switching, power reduction, and boost functions; external effects loop control is not a feature.
