From Voodoo Lab:

The rare Jordan Electronics Bosstone (circa 1968) is considered by many to be the ultimate vintage fuzz. The Voodoo Lab Superfuzz® starts with this classic fuzz design and adds unique tone and resonance circuits to create an amazing new array of fuzz tones.
The tone control delivers a wide spectrum of midrange and bass timbres, everything from an extreme gain scooped tone through a raucous, bluesy, prominent mid voicing. The resonance control is a sub-harmonic booster that lets you add an aggressive bottom end not typically found on fuzz pedals. Attack varies the gain from rich and creamy to outrageous.

Quick Features:

- Classic ‘60s fuzz sounds
