La FZ-2 Hyperfuzz est d'ailleurs une déclinaison de la Shin-Ei.
Enfin, c'est du moins ce qu'on lit ça et là.
"Although the Univox is the most well known incarnation of this circuit, Shin-ei licensed this circuit out to dozens of manufacturers, including Ibanez, Apollo, Companion, Shaftsbury, Mica, JAX, Kent, Teisco, Marlboro, Royal, and many others. With a slightly altered input stage, the circuit is identical to the Ibanez Standard Fuzz. Sometimes it was packaged with a wah pedal, or with the tone switch being a footswitch, or both. This circuit is also very similar to the famous Fender Blender and Roland Bee Baa.
More recent applications of this circuit type can be found in Guyatone's TZ-2 Fuzz, MJM China Fuzz, Black Candy Superfuzz Deluxe, Prescription Electronics' OUTBOX, BOSS's FZ-2 HYPER Fuzz, and others, although most tend to agree the newer versions do not sound quite the same."
