From the post
Here's the Mocker. It's a recreation of the on-board fuzz from the Vox UL730, used by the Beatles on Revolver and a bit on Sgt. Peppers. It's fairly simple with most of the mojo coming from the OA200 clipping diodes. Socket and experiment as I've heard 1N4148s and 1N4001s sound good. The transistors are low gain silicon so if you don't want to buy BC547As, 2N2222As or 2N5550s could be could subs (just mind the pinout). Easy fit for a 1590B. Schematic for reference.
