Universal Audio Knuckles '92 Rev F Dual Rec Amp Pedal | No Limit Guitar Co, Idaho Falls
The Universal Audio Knuckles '92 Rev F Dual Rec Amplifier pedal captures the legendary fire-breathing tone of the iconic 1992 double-rectified tube head that defined metal, punk, and rock for decades. This stereo amp and cabinet simulation pedal delivers everything from ultra-saturated high-gain mayhem to pristine full-bodied cleans, making it perfect for intermediate to professional players seeking authentic California boogie tones. With three distinct channel voicings and comprehensive tone-shaping capabilities, the Knuckles '92 brings the soul of hard-hitting tube amplification directly to your pedalboard.
Product Overview
The Knuckles '92 features Universal Audio's meticulous UAFX amp modeling technology that rigorously replicates every nuance of the original double-rectified California tube head. The pedal's robust digital processing engine accurately captures the harmonic complexity and dynamic response that made the original amplifier a favorite among iconic metalheads, punks, and rockers throughout the '90s and beyond. Its stereo design and premium construction ensure road-worthy reliability while delivering studio-quality tone.
The pedal's three distinct channels—Green, Orange, and Red—provide a comprehensive tonal palette ranging from crystalline cleans to the signature ultra-tight, gain-laden saturation that defined an entire generation of heavy music. Advanced cabinet and microphone modeling offers six different studio-ready configurations, allowing players to dial in everything from intimate recording tones to massive live sound reinforcement. The integrated TS-style overdrive and preamp boost add extra heat when needed, while the built-in noise gate ensures clean, professional performance even at extreme gain levels.
Universal Audio's UAFX mobile app unlocks expanded tone-shaping possibilities, including the ability to switch between EL34 and 6L6 power tube voicings, toggle between solid-state and tube rectification, and fine-tune every parameter of every setting. This level of customization, combined with preset storage and 4-cable mode compatibility, makes the Knuckles '92 an incredibly versatile tool for modern guitarists seeking authentic vintage tube tone without the weight and maintenance of traditional amplifier heads.
