Frequently asked questions (FAQ)

1. What makes the Rev F revision so special? The Rev F is considered by connoisseurs to be the best version of the Dual Rectifier. It has a faster attack and a more transparent sound than the later Rev G, making it much better suited for tight rhythm parts in modern rock and metal.

2. Can I connect the Knuckles ’92 directly to a PA? Yes, the pedal is designed to plug directly into an audio interface, mixing board or FRFR speaker. The built-in speaker emulations eliminate the need for a real guitar cabinet.

3. Does the pedal also contain a clean channel? Sure. Although the Knuckles is known for its gain, the “Green” mode offers beautiful, sparkling cleans that respond excellently to effects pedals.

4. Do I need the UAFX app to use the pedal? No, all the basic settings are directly accessible through the buttons. However, the app is very valuable for adjusting the noise gate, choosing additional cabinets and managing presets.

5. Does this pedal work well with a 7- or 8-string guitar? Absolutely. Tight modeling and a built-in boost function maintain definition in the low end, even with the lowest tunings and extra strings.
