I switched to this pedal from my AMT Electronics LLM-2 volume pedal. The LLM-2 was utterly unusable due to its impractically small size. This pedal is flawless. It has the smoothest sweep among all volume pedals. I enabled the fuzz compatibility mode on it and now it works like a charm with my fuzz pedal. It uses top grade components. The folks at Mission Engineering haven't compromised with any stuff on this pedal. Another notable stuff is its buffer, it's the most transparent buffer I've ever heard on a buffered volume pedal. No tonal coloration, zero noise. This pedal is perfect.
When set to operate in fuzz compatibility mode it operates at an output impedance of 10K Ohm. Another unique stuff about it is that its output jack is a TRS jack. Due to that reason I'm able to use it a expression pedal for my Uni-Vibe without the 2 x TS to TRS converter cable.
