Independent shopping perspective
The Korena take
Knuckles ’92 places three modeled amplifier channels—green, orange, and red—under pedalboard control, with power-tube and rectifier options for refining the response. A TS-style overdrive can push the modeled front end, while the built-in boost and noise gate support high-gain settings. Six mic/speaker pairings broaden the available output voices, and the UAFX app gives access to hidden controls plus saved boost and gate settings. Two 1/4-inch inputs and outputs, along with 4-cable-method support, make it usable in more involved guitar rigs.
Strong match
Who this is for
- High-gain rhythm and lead parts needing an onboard boost and noise gate.
- Guitar rigs that use the supported 4-cable method with 1/4-inch TS connections.
- Players who want to save boost and noise-gate settings through the UAFX app.
Consider the trade-offs
When to look elsewhere
- A setup without an isolated 9V DC, center-negative supply providing at least 400 mA.
