after tinkering with a pedal for a little bit i found out what was wrong with it.  it is a homemade deal stuck in a fancy box.. lol.  very interesting though.. positive and negative feedback voltage adjustment pot two seperate gain controls

anyway this is a redraw from the schematic sent to me i changed what i felt would make it more reliable

Cool, Ansil. I was thinking about what to do in a rainy day like today here, and you come with this effect. I will check if I have the parts to build this effect.

Oh ! This one seems interesting, I just wonder about transistor type (npn si?).

But, the silliest question ever, how it sounds ? Give us an idea.

Thanks Ansil, another nice work !

I don't have all the parts, but I will build this effect when I buy what I don't have.

Cause I don't understand it with any conviction.
 that 100k feedback pot is too funny, it looks like it varies between doing the FF feedback loop job and tieing Q2's collector closer to it's base.
 What I'm trying to figure out is if there's FF geneaolgy here, and is there enough of it to call it a FF derivitave? do the extra resistors tied to the base disqualify it for FF status?
 I'm interested to hear what of the sounds...what do you think.

it is a npn circuit as far as i can tell in regards to the voltage placement. it has a weird sound to it.. you can make it hollow and empty sounding but italso gives a really interesting full blown fuzzyness to it.

i might be wrong in my explanation but this is how it seems to work to me
of course we all know the voltage pot controls how much voltage drop we get. i personally didn't find this usefull except on one setting.

the first stage looks and sounds like an old lpb1 circuit.  i mean if you take the output after the the gain knob it pretty much is that. i am guessing it is around 100 gain. could be wrong since i dont' really do transistors.

the drive knob is will let you control how the second stage acts. either clean or breaking up boost. with its volume control on the end.

bascially it is an lpb1 type circuit too. i didn't even really notice that untill now.  
the feedback control varys between taking the output back to the second stage again for negative feedback thus reducing overall gain and output.  
or you can turn it the other way inducing positive feedback .. really in the middle you can't really tell its there to much but you can get it to clean up nicely with the negative feedback or you can make it self oscialte with positive feedback.  very interesting.
nice and meaty.  i was able to get a similar sounding feedback like doug's meteor clip when playing with the feedback.  


as far as a ff derivative i don't know i am not at liberty to say where the circuit came from only that i know it isn't what its supposed to be not by a long shot, cause i have seen an original and this aint even on the same page.  so i guess it could be in the ff vein
