Mastadon Fuzz Kit

This kit includes all of the parts needed to build the GuitarPCB Mastadon project. This 4-knob silicon fuzz sounds fantastic on guitar or bass! While not a clone, this compares well to the commercial Woolly Mammoth™ fuzz. The circuit board includes on-board 3PDT switch, reducing the off-board wiring.


This kit includes a 125B enclosure and black Davies 1510-style knobs. The drilled enclosure is vertical, not horizontal, to help reduce space on your pedalboard.


All of our kits include a jack for a DC power adapter but no battery snap. If you wish to add a battery snap, please add a battery snap kit to your cart in addition to the pedal kit. Please see what is provided in a kit? in our FAQ for more details of what is included and what you will need to provide to complete the project.
