Universal Audio Knuckles 92 Rev F Dual Rec Amplifier

Universal Audio Knuckles 92 Rev F Dual Rec Amplifier

The Universal Audio Knuckles ‘92 Dual Rec Amplifier Pedal is a stereo amp and cab emulation pedal with six famous mic/speaker pairs, built-in boosts, live and preset modes, and customization with the UAFX mobile app.

A watershed year for high-gain amplification, 1992 introduced the double-rectified monster that would unite metalheads, punks, and rockers alike with its fire-breathing tone. Three decades down the line, Universal Audio’s Knuckles ’92 Rev F Dual Rec Amplifier puts the punch of that all-time classic tube head on your pedalboard. This stereo amp and cab simulation pedal’s Green, Orange, and Red channel voicings supply everything from the original amp’s signature tight and ultra-saturated gain-laden sounds to a rich palette of full-bodied cleans. Six classic microphone and cabinet configurations allow you to twist and tweak Knuckles’ response to your taste, and you also get an onboard TS-style overdrive, preamp boost, and a noise gate to cut out unwanted noise. What’s more, Universal Audio’s UAFX app unlocks a host of expanded tone-shaping options, including the ability to switch between EL34 and 6L6 power tubes, change from solid-state to tube rectification, and fine-tune every element of every setting. From subterranean nu-metal riffage to buzzsaw pop-punk crunch to arguably the most pivotal metal tones of the ’90s and the aughts, Universal Audio’s Knuckles ’92 pedal comprehensively captures the soul of hard-hitting California boogie.

Multichannel madness

Universal Audio’s UAFX pedals are revered  for their uncompromising commitment to sonic accuracy, capturing every tonal nuance and harmonic detail of the amps that inspired them. And to truly replicate the vibe of a classic double-rectified amplifier, one voice simply won’t cut it — the original amp’s trio of channels ran the tonal gamut, resulting in its widespread adoption among players from disparate musical backgrounds. To match the flexibility of the original, Knuckles packs three channels: Green, Red, and Orange. Combined with this pedal’s built-in TS-style overdrive and integrated preamp boost, Knuckles tackles everything from face-melting lead tones to thunderous crunch, along with a pleasing assortment of cleans to balance out this pedal’s all-out aggression

4-cable mode offers powerful channel switching

Each pedal in Universal Audio’s UAFX series features a special “4-cable” mode accessible via the UAFX Control app, allowing you to bypass your amp’s preamp when the pedal is engaged for incredibly realistic tube-style tones. By hooking your pedal up to both your effects loop send/return and the front of amp input, you can instantly switch between your amp’s stock tone and your UAFX pedal routed straight into the power amp, effectively adding two extra channels to your amplifier. What’s more, Universal Audio designed this feature with multiple pedal setups in mind — you can connect any number of UAFX pedals in this configuration for multichannel madness.

Switch up your speakers

Most of Knuckles’ magic is in its handpicked microphone and speaker combinations, bolstered by Universal Audio’s Dynamic Room Modeling technology. Knuckles sports three of these settings right out of the box, granting you a trio of roaring 4 x 12-inch tones to choose from. Furthermore, you can connect to the UAFX app to unlock three additional cabs.

UAFX Control app

Looking to take in-depth control over even the most minute sonic parameters? Knuckles is Bluetooth and USB-C compatible with Universal Audio’s powerful UAFX app. In addition to giving you significantly enhanced editing options, the UAFX app also includes access to artist tones, custom presets, and more
