Knucklehead Tre
An ultra-high-gain 120-watt EL-34 head built for tight, chunky low-tuned riffing, with Rivera's patent-pending Foundation control for dialing in low-end gain.
About this amp
One of the highest-gain amps in Rivera’s line, built for massive sustain and a tight, controllable low end via the patent-pending Foundation control on the high-gain lead channel. Channel 2 is a big, clean rhythm channel with tremendous headroom. Used by metal and hard-rock players including members of Deftones, Anthrax, and Five Finger Death Punch. This is the non-reverb version of the Knucklehead Tre line.
