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.

Giving you six classic mic and speaker pairings, built in TS-style OD/boost, and noise gate, Knuckles puts the authentic genre-defining sound of one of the world's most ferocious high-gain amps under your boots.

Whether you seek the gritty power chords of punk and alternative anthems by the likes of Dave Grohl and Incubus or the complex aggression of Nevermore and Dream Theater, Knuckles ‘92 puts one of the most versatile multi-channel amps ever made right on your pedalboard.

Use the famed green, orange, and red channels to explore perfect cleans to bone-crushing crunch and smoldering lead sounds. Then experiment with EL-34 or 6L6 power tubes and switch between solid-state or tube rectifiers for ultimate control and feel under your fingertips

Knuckles '92 is equipped with a classic TS-style overdrive — a tried and true component for tight, articulate playing — and an integrated preamp boost that’s famous for sculpted modern metal tones. And with its built-in noise gate giving clear sound even at extreme gain settings, you’ll melt faces the minute you power it up.

Experiment with six mic and speaker pairings used on countless iconic records. From alt rock anthems to de-tuned nu-metal brutality, Knuckles ‘92 captures the full essence of playing through one of the greatest aggressive amps ever made.

Using its rear panel USB-to-MIDI connection, Knuckles '92 drops straight into any programmable MIDI rig, receiving preset changes and realtime control of boosts, EQ, and more.
