Ibanez Standard Fuzz modified by EATYOURGUITAR
This circuit was sold under many names from different manufacturers. Ibanez does not own the circuit, my schematics, or my PCB. It is old anyway. The mid scoop is similar to a big muff but is also more extreme like a shin-ei companion FY-2. The FY-2 suffered from low output due to the losses in the extreme mid scoop. Standard Fuzz has a more narrow notch filter. It is not exactly a scoop although it is extreme. Most notes pass through the filter just fine but they all have vastly different timbre up and down the neck. There is also a buffer at the input and output to keep the volume as loud as you want. The vintage standard fuzz is inferior to this PCB right here. There is now a trimmer to set the volume of the tone stack bypass footswitch at, above, or below the volume coming out of the tonestack. I know there are people using flat mids + volume boost for solos. It can also be set to have mid scoop + volume boost for solos. You can break this trimmer out to the front panel on a 25KB pot for a super deluxe standard fuzz. Another important feature on this PCB is that you can mount 6 diodes of various types and wire them in simple or complex combinations.
