This won't actually work.

A Fuzz Face works the way it does because it actually gets affected by the guitar's impedance changing as you work the knobs on the guitar and pick differently. The Fuzz Face has minimal input filtering, the guitar's knobs actually change the bias of the first transistor IIRC and cause massive changes in sound.

If you stick a buffer in front of it that interaction is gone and there is nothing you can stick after the buffer to bring it back. You pretty much have to plug the guitar directly into a Fuzz Face for it to work as intended. There are even constant arguments about putting the Wah in front of the FF or after it. I'm not sure if the article even has it right or whether Hendrix did it differently at different times. Other articles show a different order of the effects.

There are other fuzz circuits that behave differently and work better with buffers and would be more uniform when used with other types of instruments or with electric guitars with active pickups (which are buffered).

E.x. I have a Tone Bender and have had several Fuzzes in the "Big Muff" category along with one that was based on the Fox Tone Machine. The Tone Bender and Big Muff can't clean up at all like the Fuzz Face via the guitar controls, and IIRC the Fox Tone Machine is somewhere in the middle. The Fuzz Face when setup correctly is really quite amazing as you can go crystal clear to crushing fuzz with your volume knob on the guitar. When you've tried it you realize Jimi Hendrix was doing it constantly in an amazing way.
