From the post
Not the Maestro stompbox that produced the classic "Satisfaction" tone, but a good sounding fuzz nonetheless. This came out during the Norlin era of Gibson/Maestro in the 70s. The original used a TL022 opamp, but I've listed the TL072 because it's more likely to be in your parts bin. I've also up'ed the power filter cap from 2.2µ (which wouldn't do a lot) to 47µ.
Here's a demo of an original:
