Product Description
The name is irrelevant - Master Control, Duo Fuzz or Super Fuzz - the sound is what counts: it's basically two very different shades of monstrous filth - ripping chainsaw fuzz or brutal octave-ish wildness.
This one has lost it's badge - it may well have been a "Companion" or one of the other numerous re-badged versions that Shin-ei made, at least some of which had this identical case (e.g. the Jax FY-6 Fuzz Master, Mayfair Model No. 9540 Super Fuzz and Teisco TF-1 Fuzz to name three - if you want a full run down then the effectsdatabase Shin-ei FY-6 page is the place).
Integral to the tone of a list as long as your arm of guitar icons (check the Wikipedia Univox Super Fuzz page) - if you don't yet have one of these in your fuzz arsenal then this is a great example.
