Mattrix Fuzz


This is our Mattrix Fuzz

In Cooperation with the Band My Sleeping Karma and their Bass player Matte Vandeven, we have developed and designed the Mattrix Fuzz according to his directions. Enjoy the My Sleeping Karma Live and Studio Sound.

Based on the vintage Russian Muff from Matte, we created him an updated version of this legendary pedal, put it in a smaller enclosure and fitted it with lots of new features, to provide him and you with an additional sound spectrum. A mid control was added, to help regulate these frequencies (scoop). Additionally each clipping stage has its own switch. With the left switch (Stage 1), you can choose between Silicon - No clipping - Germanium. The right switch (Stage 2) adds another two clipping variations. With both switches in the lower position, you get the clipping stages of the Green Muff. Everything else is up to you to find your personal sound! From Fuzz/Distortion to smooth Overdrive. Everything is possible.




  • Handbuilt in Germany
  • Only high grade film capacitors and resistors were used for their superior sound and response
  • 2 Switches to control both clipping stages individually, to get everything from Clean Boost to Overdrive to Fuzz sounds
  • Completly True Bypass
  • Battery connection and 9V power jack (barrel plug like Boss - 2.1mm center negative)
  • 3.7” x 4.9” x 1.3" in size (94mm x 126mm x 34mm) - height excludes knobs and switches
