One more for the vintage Japanese Fuzz collection   The Ace Tone FM-2 Fuzz Master – a variation on the venerable Super Fuzz.

It’s a little different as the “Expander” control is missing (bypassed), which is the same as running it full-tilt all the time.  It also uses silicon diodes instead of germanium and has a strange “Fuzz Adjustment” control, which is more of tone control.  Apart from a few little quirks, it’s a member of the Super Fuzz family.
