IBANEZ: No59 Standard Fuzz

So it's a Super Fuzz...  well, almost.   The Ibanez No59 Standard Fuzz has a JFET booster, as opposed to the more complicated 2 x transistor arrangement in the Univox Super Fuzz, and a very slight change in the tone filter section; apart from that, same same.

It's more Super Fuzz than the Ibanez Standard Wau Fuzz, which has the same tone section as a Super Fuzz.  The Standard Wau has a slightly different arrangement.

The notch filter is quite a prominent part of the sound, it's a bridged-t notch filter, and you can find out more about them here.   It's very similar to the Univox Super Fuzz filter but with a cane in capacitor value, lowering the notch frequency slightly.   While the circuit looks like a Big Muff tone stack, it has been tuned to recreate a notch filter - this is also conveniently explained via the previous link.
