This fuzz face inspired version has silicon BC109B transistors that are kind of low gain compared to the 109C. The fuzz has a totally reworked circuit to be able to work with these transistors. Backing off the volume knob you can go from fuzz to OD to sparkling cleans. One of the best Fuzz Faces variants there is. Pure magic.
Please note, due to the 100% handmade nature of these pedals the finish does vary slightly from unit to unit.
