A combination of the 2 concepts, amp simulation and diode compression.  Joe has hinted at this and I just combined schematics.  Adding a Mu-Amp or Blackfire stage at the end might add more of a power amp affect.  Let me know how it works.  Thanks to Runoffgroove.com and Joe Davidson.   :icon_cool:

Tried this a couple of weeks ago, I may have a small "bug" somewhere, as the controls
all work, sound is pretty good ( subbed in a kind of Big Muff tone pot ) but I have some
intermittant "high hash" going on, splats of noise sounding a bit like a constantly adjusted
dirty pot ( when nothing is being turned )
Need to return to it ( amongst others ) but overall it has a good sound and is very nice
at clean settings.
Dont know if it's important, but I used Ge diodes for all stages 1N90's

Nice "combo" idea

MM,

EDIT :
Turns out to be Q1, 100k trimmer can't get to 4.5v always jumps above causing the noise
tried a few J201's MPF102 and 5457 !
Possibly needs a new trimmer ....

When I subbed GE's for SI's in the Vulcan stages, I was suprised that they seemed to have the same tonal difference as when using them for clipping diodes.  The GE's were quieter and fuzzier.  I wouldn't think they account for the problem mentioned.  IIRC you can by-pass the diodes and hear just the Jfets compressing/distorting.  Glad you tried it.   :icon_cool:
