From the post
Here is a rare old and quite unique circuit that hasn't been traced before. With lots of help from AlexS and cobyjoe we managed to trace it and a have a working clone. So what is it? Not to be confused with the Supa Sustain, this is a quite gnarly and fat fuzz with lots of output on tap. Some parts of the circuit resembles to a Fuzzrite (Q2 and Q3) with a feedback path that that has lots of odd things happening (Q4, Q1, D1 D2).
There is also a 2 switch version with an added switchable transistor stage but I haven't managed to trace it yet....
