Like new condition. Bought as a backup to another Archer pedal that I have on my pedalboard. Played just a couple times in the house and put back in the box for safe keeping. Here's some info from the maker:
The Jeff is a special pedal for those seeking the ultimate Klone. Don’t take our word for it though. A certain “Freeway Jam” guitarist replaced his gold Centaur for this one! (Jeff Beck)
The Jeff is an exact tribute to that legendary pedal. Featuring NOS germanium diodes and a few other internal tweaks the Jeff is the Klone to end all pedals
Compared to the Archer and iKon this pedal combines the elements of both pedals into a true 1:1 pedal.

And here's some info from an online retailer:
The Jeff Archer from J. Rockett Audio Designs is a limited-edition version of the company’s massively popular high-headroom “transparent” overdrive pedal. This stompbox still features the coveted K-style harmonic saturation of the J. Rockett’s original unit, but it ups the ante by replacing some key components, including the germanium diodes, with vintage NOS variants. These are the same mods on legendary guitarist Jeff Beck’s unit, and you can hear the Jeff Archer all over his 2016 album, Loud Hailer, and live with his current touring board. The Jeff Archer is organic, responsive, and versatile, with a smooth and sweet top-end response that sounds magnificent through a wah pedal. Guitarists at Sweetwater have found that the Jeff Archer pairs well with any number of guitars and amps, from single-coils and small combos to overwound humbuckers and British-style stacks!
