Thanks very much. Every bit helps. I had a few questions about your notes, in brackets below.

THE “RAM’S HEAD” BIG MUFF – VERSION 2

TYPO>You list 2N5088 as a PNP transistor, it should be NPN.
(Funny. I have gone back and forth on that one, as I have been told both. I know now it is negative ground, just forgot I never fixed it!)

Civil war metal can transistors are called a “TO-18” package, the black plastic ones have a “TO-92” package.
(Do you know what the actual Russian transistor numbers were?)

THE SOVTEK “GREEN RUSSIAN” BIG MUFF

Only two component changes where made from the civil war muffs.
They contained high gain transistors.
(I have been told these were lower gain/lower power than the US Muff transistors. I think I read that on a few Muff mod forums as well. Do you mean they are actually higher gain than the US versions, or that the Russian Es are classified as high gain?)

THE SOVTEK “BLACK RUSSIAN” BIG MUFF (SMALL BOX)

There are two versions of this box, one with four screws (current) and the one before it with six screws which was heavy duty.
(yeah, I have both pictured, just never updated the descrip)

THE USA RE-ISSUE RED AND BLACK BIG MUFF – VERSION 8
3003B and 3003C use BC550C transistors.
(Thanks. I just added these with the years. I would like to see the schematics for all three. Are there component changes or just some value changes?)

THE LITTLE BIG MUFF RE-ISSUE – VERSION 9
This isn’t a RI of the NYC in a smaller box, its schematic differs significantly form the NYC, you could call it a variation of the NYC.
(I knew that as well, but I never updated the descrip here either. I just fixed that one. That’s the main reason I gave this a new version number)

Thanks again.

Yes, I think I have all of that info on my site. I just updated the op-amp numbers. Apparently I had a rare op-amp. I have not put any of the schematics on my site since they are on numerous other sites, but it would be nice to have one wesite that includes them all to reference. Let me know when you get yours up and I’ll link to it.

How do you like the Tonewicker? I still have not gotten around to buying one. I keep blowing my extra cash on vintage Muffs!

By the way, if you don’t want your pix on my site for some reason let me know and I’ll trade them out for others. I have hundreds of Muff pix, and I probably have too much repetition already for a few versions.

Have you looked at the circuit board yet? Is it an early op-amp? I have never seen one with that line in black. They would have had to cut the art apart differently to make the black silk screen include that line. I have had some experience with industrial screen printing and we used to just cut the transparencies apart with an exacto knife and mount the individual parts on each color screen to burn in the art. It is an easy mistake to make.

The picture is not there anymore, but I think this was it. It’s an OEM Ram’s Head.

Those are good articles, some of the first ones I found on the web when I started researching Big Muffs. Some of the dates are wrong, but a good history.

I have some EH history on my Big Muff page, but it mostly relates to the Big Muffs. I pulled info from practically every source on the web, music magazines, stomp box books, and talking to other collectors and sellers.
