The ZVEX Reverse Fuzz Factory RSCFF2602 is a one-off fuzz pedal built by ZVEX at its mod bench. The maker describes it as "a frankenstein Fuzz Factory made from odds 'n' ends at the shop," meaning it was assembled from spare parts on hand rather than built to a standard production run. It belongs to the wider family of Fuzz Factory variants, which also includes models like the Reverse Fuzz Factory and the Reverse Fuzz Factory Engraved.1
What it does
The circuit is built around Reverse Spam Can transistors, which ZVEX says "sound amazing and squishy." The maker traces its lineage to "many 1960s fuzz boxes with reverse polarity," placing it in the same territory as the vintage germanium fuzzes that inspired the original Fuzz Factory design.1
The "reverse" in the name refers to more than the transistors: the pedal runs on reverse polarity power. That matters for how you power it on a board1.
Because the pedal uses reverse polarity power, ZVEX suggests running it on a 9V battery or with "one of those little red plugs," a polarity-adapter plug that flips a standard center-negative supply. It cannot be connected to a normal pedalboard power output without one.1
Availability and price
ZVEX listed the RSCFF2602 at $449.00 USD as of 25 October 2026. As a bench-built one-off rather than a catalog product, it is not something the maker keeps in production; players interested in the reverse-polarity Fuzz Factory circuit may want to look at the related Reverse Fuzz Factory versions or other fuzz pedals in the ZVEX range.1
