From the post
Per request. A slightly modernized take on a Moog designed Fuzz/compressor hailing back from the 70s. The signal path remains true to the original but the rotary switch has been removed in favour for a variable fuzz control. And the two compressor settings is now fed through a toggle switch. The CD4007AE IC might be hard to source but it is avaiable at Ebay.
Schematic is avaiable HERE.

- Diode numbering: the board draws D1 on the 9v strip (row B) and D2, D3 as an antiparallel pair at columns 24-25, but the legend says 'D1-D2: 1N4148, D5: 1N5817' and no D3. Entered by position: board D1 = 1N5817 (supply), board D2 and D3 = 1N4148 (clipping pair); this is an inference, not printed.
