Here's what Fredric Effects says about the Super Unpleasant Companion Fuzz:
The Fredric Effects Nouveau Super Unpleasant Companion is a combined Shin-Ei FY-2 and FY-6 Superfuzz clone in a custom enclosure which is slightly smaller than our Classic Super Unpleasant Companion. It features top-mounted jacks and has the controls on the front face.
The circuit is a faithful reproduction of both the FY-2 Companion Fuzz and FY-6 Superfuzz. Choose either with the toggle switch and the controls are: FY-2: Fuzztone, Volume FY-6: Gain/Sustain, Volume, tone switch
