Up for sale, a B.G. Harding Zonk II SI (silicon) in mint condition and in perfect working order, complete with the original box. A modern clone of the vintage Zonk II (itself a more consistent-sounding revision of the Mk I Zonk Machine), this pedal features an external bias control, and this pedal excels at the “crumbly gated tones” that made the Zonk a favorite fuzz. The pair of BC108B silicon transistors also clean up great when rolling back the guitar’s volume, something not possible with germanium iterations.

There’s barely a mark on the enclosure, and the graphics are pristine. The original box is included.
