I was building an NPN Fuzz Face and wired the 2.2uf cap as a variable capacitor and voila! It worked great as a Bass control (50k Lin pot). I wired it with the capacitor ( - side of the cap from the input) tied to Lug 2, and the hole where the + side of the cap would''ve gone wired to lug 3. Here is where my question enters in.
