Looking at the different schematics a few things are going on.
So the use of emitter bypass caps might not get the "sound"

I tried adding two non-electro 220uF caps around the emitter resisters on Q2 and Q3.  No difference that I could tell.  Do the caps have to be electro's?  If so why is that?  I removed the caps again until I get some 220uF electros.  Or maybe I should use a different cap value also.  I haven't installed the whole mod yet at this point so that could be an issue.

I used a film cap to bypass Q3's emitter and there is a differance. I'ts not THAT  BMP sound as Gus said (it's clearer and more distortiony as I've mentioned before) but it's cool :)

BTW it was a much smaller cap than 220uf to accent mainly the high end - as the BMP has enough bottom

What I find amazing is that for years people were trying to get THE muff sound and AFAIK it was from a TRIANGLE big muff. Well, the "triangle" version has been online for so long and I don't remember anyone going nuts about it.

Someone out there has my 76' Big Muff and that one was pretty darn good. J.C. posted mods that really affect the response of the Big Muff (there are in this forum archives) and I have had great success with those mods.

True, built the triangle a year or so ago, enjoyed it for a while, but recently gave it to a friend for
a birthday present.
I found it a bit thin, not as big and fat as a newer BM, it sounded quite similar to several other
fuzzes and just got left gathering dust.
The new owner loves it BTW !! ??

Thanks Yun, looks like an interesting mod to try.

hopefully this will help:



I had some pics of the insides of a creammy dreamer, now i modified it in MS Paint to show the resistor values. 

i THINK that i modified the pic correctly............

Could you post that again? It's not working anymore. Thanks!

here's what i *believe* to be the creammy dreamer. 

I took the triangle NPN BMP and redrew in the creammy dreamer mods.... ENJOY



Pic not working

That photo is on the net somewhere. I would google it and see what you get. People delete photos for viewing after a while do to bandwidth and the need to make more space on their site that's hosting it. I'm sure if you PM them they could email you a copy. It's not a big deal. The board side is covered in goop so your not getting treated to anything. It's just the underside's traces revealed that those points went to ground without a resistor.

Please note:

-The 82K resistors from base to ground (of the transistors); sounds better if you ommit these, but that's just my ears, man. 
-i'm still not sure of what the tone stack is on the creammy dreammer. 

HOWEVER;

Sounds like this:

-.003uf
-.047uf (on the middle lug of the tone control)
-.02uf
