Overview

Bring the raw power and unmistakable aggression of a legendary ’90s tube amp to your pedalboard with the Universal Audio Knuckles '92 Rev F Dual Rec Amplifier Pedal. Built for guitarists who crave the genre-defining tones of punk, alt-rock, and metal, Knuckles gives you all the tight, roaring sound of the famous Dual Rectifier Rev F—no giant head or cab required.

Universal Audio’s dual-engine UAFX platform faithfully captures the full end-to-end signal path—delivering realistic, three-dimensional amp, cabinet, and mic emulation. Choose between three footswitchable channels: crystal-clear cleans, bold crunch, and full-tilt distortion. Dial in your favorite tube flavor with selectable EL-34 or 6L6 power tubes and go from spongy to ultra-tight with switchable tube or solid-state rectification.

The built-in TS-style overdrive, preamp boost, and precision noise gate let you sculpt everything from tight rhythm metal to saturated lead tones—no extra pedals needed. Experiment with six studio-grade mic/cab pairings, or bypass the cab/mic modeling to use Knuckles as the ultimate preamp or overdrive in your existing amp rig.

Unlock even more creative potential with the UAFX Control mobile app: customize footswitches, deep-edit tones, set gate and boost preferences, and explore presets designed by top artists in the alt-rock and metal worlds.

Rugged Universal Audio build quality, powerful digital modeling, and a suite of creative features make the Knuckles ’92 a must-have for modern guitarists seeking the best in high-gain tone.
