Super-sized, highly tweakable Muff-inspired tones.

Welcome to a new era of the most iconic fuzz sound the world has ever known!

The Big Muff’s huge and super saturated tone defined the signature sound of countless artists over the past decades.

Its circuit had a massive impact on the entire industry and has been modified over and over and over again.

You think it’s all been done, right? Oh boy does KMA have a surprise for you here!

The Chief Disruptor aims to offer more Big Muff-style tones than, well, a Big Muff!

The pedal bundles a huge amount of tone-shaping control, plus three classic Muff-style voices in a single box.

There are master and clean dials, while the oversized 'Disruption' knob handles gain control.

The Vintage Mode will give you every shade of discrete overdrive.

The Tight Mode serves up a more focused and modern tone with less bass and super crisp harmonics.

Heavy Mode is the essence of what we all love about Muffs: heavy, sustaining and crazy thick fuzzy distortion, with bone-shaking lows and chewy mids.

Plus, KMA carefully balanced the gain control to achieve total control of even the slightest harmonic nuances.

Whether you’re looking for low gain drive, crunchy medium gain rhythm tones, singing or saturated lead sounds, the Disruption can cover all your needs!

KMA Chief Disruptor Fuzz features:

• The ultimate Muff-style drive!

• 3 distinctive gain structures.

• Pre or Post Clean Blend for a tight low end.

• Active Bass and Treble EQ.

• Separate Mid EQ with footswitch and frequency control.

• Top-Boost for crunchier harmonics.

• External Expression control: allows for filter or pseudo-phase tones.

• Internal controls for Mid Q and Top Boost Level.

• True Bypass.

• Power: 9V DC.

• Current Draw: 160mA.
