GermanDescription
The Phobos Fuzz is a clone of the Coloursound Tone Bender Mark 3 (three-knob). The Phobos project has a voltage inverter which allows you to power the effect with a standard center-negative adapter while maintaining the positive-ground operation of the original. The pcb also includes space for biasing trim pots so you can dial in a perfect bias without having to swap out resistors.
This kit contains the PCB and all necessary parts. The enclosure can be selected, please select 3 or 4 knobs for 6,3mm shaft separately.
