Presenting the all new Universal Audio Knuckles 1992 Rev. F Dual Rec Amp Simulator Pedal.
The UAFX Knuckles ‘92 Rev F 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/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.
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.
