Happy #FuzzFriday, everybody! The Pharaoh is a variation of the classic Big Muff circuit, and one of the best out there. It features a modified tone stack with an added highs control. There are also 2 toggle switches added, one that switches between 2 resistors at the input, and one that switches the clipping diodes of the 2nd gain stage. This last switch allows you to select standard silicon diodes, asymmetrical germanium diodes, or no diodes at all. I’ve added a pull down resistor to the PCB side in case you encounter switch popping. It might fit in a 1590B, but if it were me, I’d feel more comfortable with a 125B. Speaking of which, here’s the drilling template for a 125B.
Edit: Q1 should be an MPSA18 and Q2-4 are 2N5089s.
