Fuzz pedals are normally quite a nasally sounding things often with very little low or mid frequencies. Muffs are slightly different in this though many would argue muffs sit more in distortion territory than fuzz.
Then we have germanium fuzzes which are are little more delicate, dynamic but still roar in a way to tear ones face off when pushed hard enough. The dilemma comes when we want all of the features as there wasn't much out there allowing this.
And that's why Jam named their fuzz ... Eureka! What they created is a germanium sounding muff style fuzz with 3 switchable low end options and the ability to push it hard in the lightening bolt setting for gated spluttery tones.
This is one pedal which behaves very differently through different rigs and it just so happens that's exactly what Tonepedia provides. Go ahead and see how it behaves differently with single coils into a fender amp compared to humbukers through an AC30.
