From the vendor
A layout of Cees van Eijk's BC108 Dirtbag. The Dirty Bird Fuzz is a PCB based on the Skidmark Pedals Dirtbag BC108 (MK2). This in turn is a variation of the Skreddy Lunar Module with a different voicing and some bonus features. While the Dirtbag was laid out for 1590BB, this version fits into a 125B. There are no boutique parts for this pedal. The layout is based on the schematic, from a PDF posted on the PPCB forums by member ITG6.
