Colorsound Sustain Module 1 switch version

 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....

ETI Fuzztone

 Designed by Dan Coggins (Lovetone and Dinosaural). Despite its name it is more like an overdrive with asymmetric soft clipping and a tone control that pans between a low pass filter and a voltage divider.

 Pretty cool design; a Rat and a Tubescreamer in one box with a "Contour" control that looks like the Mid control in Wampler Triple Wreck...

 

...and the requested schematic.
