Product Information

Get the raw sound of punk, alt rock, and metal under your boots.

The Knuckles '92 Dual Rec Amplifier delivers the searing high-gain tone that powered legendary punk, alt rock, and metal bands from Foo Fighters and Incubus to Nevermore, Dream Theater, and more. With six classic mic/speaker pairings, a built-in TS-style overdrive/boost, and an integrated noise gate, Knuckles puts the authentic genre-defining sound of one of the world's most ferocious high-gain amps on your pedalboard.

Plug into the California King of High Gain
Whether you want gritty, explosive power-chord punch or complex progressive metal aggression, Knuckles ’92 gives you the legendary multi-channel high-gain amp experience — right at your feet.

Explore a Range of Rectifier Tones
Choose between green, orange, and red channels to move from shimmering cleans to crushing rhythm tones and soaring leads. Switch between EL-34 or 6L6 tubes, and solid-state or tube rectifier modes for the exact response and feel you crave.

Play Through Perfect Preamp Boosts
Shape tight, articulate rhythm tone with the built-in TS-style overdrive, or engage the integrated preamp boost for sculpted, modern high-gain saturation. A transparent noise gate keeps even extreme gain settings controlled and clear.
