This is the Super Fuzz + Op Amp Muff. This specific pedal was made with the best switches on hand.
The Op Amp muff has quite a bit more clarity and a more refined sound, a bit less muddy but still aggressive and massive like its brother.
The mode toggle bypasses the tone control section for a neutral sounding fuzz for bass players or for those who want their guitars natural character to shine through this circuit.
A great way to achieve the smashing pumpkins tone.
The super fuzz side is a vintage octave up fuzz, a recreation of the offering by Univox. These pedals consistently sell for an upwards of $500 these days, they are highly sought after, and known as a more gainy, less noisy version of the Octavia circuit.
Personally it is my favorite vintage fuzz circuit by far and is the basis of many of my favorite modern fuzz pedals. This circuit truly is a great example of what an Octave Up Fuzz should be.
Diddly darn it. These are two damn amazing circuits in a pedalboard friendly enclosure. What more could you want?
