Berlin-based builder KMA Machines has unveiled the Chief Disruptor fuzz pedal. The pedal aims to offer more Big Muff-style tones than, well, a Big Muff – bundling a huge amount of tone-shaping control, plus three classic Big Muff-style ‘voices’, into a single box.

Central to the build are a choice of three gain structures, which can be selected by a toggle switch on the top left and reflect classic sounds from across the Big Muff fuzz genre… These include Vintage, Tight and Heavy modes. There are master and clean dials, while the oversized 'Disruption' knob handles gain control.
