I’ve been using the UAFX Knuckles, and honestly, it surprised me in a big way. With my Boogie/Mesa Dual Rectifier rig plus MIDI, this thing basically kills the need to haul a full head and cab around. Most people can’t crank a Dual Rec to the volume it actually needs, and not everyone has the space or gear to mic it properly.
Once you add a boost, the 1176, and some EQ, the Knuckles setup gives you that whole “amp + studio chain” feel right in your pocket. It’s kind of wild how close it gets, and it makes the big rig feel unnecessary for most situations.
The only real downside is that it’s power‑hungry, but I’m running it off a Voodoo Lab Pedal Power 3 without any issues.
