KMA Machines Chief Disruptor Fundamental Fuzz Distortion Guitar Pedal
Welcome to a new era of the most iconic fuzz / distortion sound the world has ever known. You know, that epically huge and super saturated tone (some might call it big and Muffy) that has defined the signature sound of so many artists and countless records in the past few decades.
It's arguably one of the pedals with the biggest impact on the entire industry, which has seen it modified over and over again. So much that you think it's all been done, right? Oh boy do we have a surprise for you right now, right here!
Holding three different Gain Modes, a pre- or post-EQ Clean Blend, active Bass and Treble controls, a foot-switchable and expression-controllable parametric Mid-EQ as well as a switchable top-boost for even more raspy, grinding bite, CHIEF DISRUPTOR is the most flexible, beautifully balanced and LOUDEST muff-style pedal you'll ever hear!
In-Depth Controls
- MASTER: Sets the overall volume
- DISRUPTION: Sets the amount of Fuzz / Distortion
- CLEAN: Blends in the input signal
- VOICING (Toggle-Switch): TIGHT: modern Big Muff sound with tight lows, focused mids and a crisp top end
- , VTG (Vintage): Classy Muff Sound, low- to mid-gain distortion, balanced frequency response, HEAVY: full blast Big Muff sound with massive low end and plenty of gain
- TOP BOOST (Toggle-Switch)L Turns on / off a high-mid boost for a sharp attack and increased top end distortion
- BLEND (Toggle-Switch): Sets the insert point of the clean blend, either PRE EQ or POST EQ
- LOWS: Active bass control to boost or cut your low end (+/-15dB)
- HIGHS: Active treble control to boost or cut your high end (+/-15dB)
- MIDS CUT / BOOST: Sets the centre frequency of the mid-eq (from 100 Hz to 2 kHz)
- MIDS FREQ: Active semi-parametric EQ for high frequency boost (up)/ cut(down) with adjustable centre-frequency between 1.4-5 kHz via below potentiometer (midpoint: 2 kHz)
- Footswitches - MIDS: Activates the parametric MID-EQ (yellow LED indicates the on/off state), ENGAGE: Activates the pedal (red LED indicates the on / off state)
- Jacks - INPUT (Arrow Down): Input for your incoming signal, OUTPUT (Arrow Up): Outgoing Signal
- EXP (Expression Pedal): Input for an expression pedal to change the mid-eq centre-frequency hands-free. Useful for fast and quacky wah-like sounds or slow and enveloping phaser-like sweeps.
