Super Fuzz Sustainer

[dazed and confused]

I have just been offered this for a snip!
Looks cool, but not sure if I really like the sound, seems like more of a distortion unit to me. I'll play it some more before I decide.
We've seen them before, but anyone know anything about them?
Peace

Looks like a Big Muff derivative, though the blurry gut shot makes it tough to tell for certain
