Universal Audio KNUCKLES 92 Overview

Plug into the California King of High Gain
Get the bare-knuckled tone that only a '90s legend can attain with the Knuckles '92 Rev F Dual Rec Amplifier from Universal Audio. This UAFX pedal emulates a classic Mesa/Boogie dual-rectifier amp and offers players three switchable channels, a TS-style OD and boost, a noise gate, six cab sims, and selectable solid-state or tube rectifiers.

Ideal for punk, alt rock, and metal, Knuckles '92 sports UA's signature UAFX dual engine for a truly authentic emulation. With the UAFX app (Bluetooth or USB-C), you can deeply edit most parameters and functions, select output tube types (6L6 or EL-34), and access three bonus cabs not available directly on the pedal. Groundbreaking physical room modeling, derived from UA's award-winning OX Amp Top Box, is on tap for use with the pedals mic and speaker pairings, providing a true amp in a box. The Knuckles '92 sports stereo I/O, allowing you to experiment with output routings, stereo cabinet pairings, and engage the 4-cable method for inserting drive FX into your amp signal chain.

Explore a Range of Rectifier Tones
Use the famed green, orange, and red channels to explore perfect cleans, 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.
Play Through Perfect Preamp Boosts
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.
Six Epic Mic and Speaker Pairings
Experiment with six mic and speaker pairings used on countless iconic records, from alt-rock anthems to detuned nu-metal brutality, Knuckles ‘92 captures the full essence of playing through one of the greatest aggressive amps ever made.
