Maestro Sustainer schemo??

[toneman]

Hey Stompboxers,
anyone have a schemo of the Maestro Sustainer 2 share???
i have schemo 4 a  "FuzzTain" by Maestro, but not *the* "Sustainer".
heard from a web friend that pcb is sealed with potting compund.
he said that when it died,  he just threw it out..  
i have jpgs of the Sustainer, but no schemos.  
Box/case is similar to FuzzTain.
The FuzzStain uses neither LED/resistor nor CA3080.
It uses a 4007 as a triple buffer in the feedback path
with 2 1N4148s for fuzz & rectification for sustain.
Cheap 2 build.  My friend said it was a great pedal!!
A Sustainer Manual/or just schemo would B very nice..  
anyone got??
thanx!!
