The Mids knob is one of the features more common in Big Muff variants, allowing it to overcome the original circuit’s infamous mid-scooped character. Two internal switches allow this pedal to deliver slightly different voicings, from the lower-gain yet smoother and warmer Russian Muff to the more modern, higher gain NYC-style Muff tone.
Another internal mod switch transforms the pedal in a Supa Fuzz (!!!) with its huge bottom-end that works great also on bass.
Dazatronyx Big Fuzz, Builder’s Notes
The Big Fuzz is a muff circuit, which has been made to factor all of my favourite elements from the many various models. Further, some improvements have been made to improve user interaction, which are otherwise lacking in traditional builds.
The classic design varied greatly over the years, being made in various locations to different schematics and ever-changing component values. One large reason I suspect some models are still higher favoured now, is for their amount of mid-scoop. This is a famous love-hate element of the circuit, however, having this second tone knob adjustment is incredibly helpful.
There are two internal mod switches to independently change the gain stages. This goes from the Russian style lower gain, which is famously a bit smoother and proportionately warmer in the top-end, to the modern NYC high gain which is a bit more aggressive. Combing this with the mid knob means you can achieve tones alike to most releases.
There is also an internal mod switch to transform the circuit to work as a Supa Fuzz (Marshal, Sola Sound). This has a huge bottom-end wrapping, and is the preferred mode for bass players.
