Fuzz Face w/ diode feedback loop

[jayp5150]

I've searched for this, but everything is referring to shunting diodes to ground after Q2.  I was wanting to do a FF-based circuit with a switchable diode feedback loop on Q2 (like the muffer or bazz fuss).

Has anyone done this?  And would it be better to do it on Q1, or Q2?  I was figuring Q2, since this is where the fuzz is coming from in the 1st place, right?  I was thinking that if I put it on Q1, it would add a bit of grit, but lower the signal hitting Q2, which would end up having a marginal effect overall.

Am I on base here?  Any help/opinions are appreciated.

Ill chime on this one, since I don't really know exactly what's going on there. Sometimes just getting a little conversation going novice style gets the 'now how to's to straighten things out !!!
 Q1 C does get up to enough voltage to make difference from ground to reach threshold.
 I go and read tech of FF again...

Tim Escobedo explored this concept, as seen here (bottom of page):

I guess what I was talking about is similar to what's used in the BMP.

I'll just try it and see what happens.

Please understand, I wasn't saying "never mind, it's already been done," but rather "here's how someone else approached it."

Oh, I know, I was just playing around.  Sorry if that came across wrong.  No hard feelings at all.

I'm still in the wide part of the learning curve, yet I'm not content to build stuff exactly like it is on the schematic.  That's the hot rodder in me.
