Universal Audio UA‑KNUCKLES UAFX ANTI Knuckles '92 Dual Rec Amplifier

The Universal Audio Knuckles '92 Dual Rec Amplifier pedal brings the ferocious high-gain tones of the legendary 1992 Rev F Dual Rectifier amplifier to your pedalboard. Designed for guitarists seeking the iconic sounds that defined '90s punk, alt rock, and metal, this pedal delivers authentic amp emulation with the convenience of a compact stompbox.

Equipped with a powerful UAFX dual-engine, the Knuckles '92 offers a comprehensive suite of features including TS-style overdrive, preamp boost, noise gate, and selectable solid-state or tube rectification. Its three-channel design—Green, Orange, and Red—provides a versatile range from pristine cleans to aggressive leads. Additionally, six classic mic and speaker pairings, along with groundbreaking physical room modeling derived from UA’s award-winning OX Amp Top Box, allow for extensive tonal customization. Integration with the UAFX Control mobile app further enhances user control, enabling preset management and deeper parameter adjustments.
