“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. 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, Prescription Electronics’ Outbox, Boss’s Hyper Fuzz, and others, although most agree the newer versions do not sound quite the same.”
