Your new big muff is the opamp version BTW, it doesnt use any transistors. One of my favorite versions!

They have always had that pic (them knobs), they haven’t updated it since they re-issued it i think.

What people need to remember is that EVERY big muff varies, no matter what issue it is.
EHX/SOVTEK didn’t change parts and values just cause they changed a font!

I have schematics traced from tons of alleged variations of the same version big muffs and they are all the same values used.

Buy any two 1981 3034 big muffs or any two 2005 3003-A big muffs, they will sound different. do the same with any two identical green sovteks, they will sound different.

FYI, they will always sound like a big muff but there’s always slight differences.

BTW, I’ve modded Black sovteks into green soveks and couldnt tell the difference, they sounded the same as before the mod, and you shouldn’t be able to either considering its only two resistors that have a sightly different value.

So remember, its very unusual to find any two muffs of the same model to sound the same let alone different models!

What it generally comes down to is: TOLERANCES will effect the sound a lot. And to a smaller degree TYPE of parts will effect it too. And from experience and observation vintage EHX and Sovtek tolerances were all over the place,drastically!

An example of majpr tolerance difference is the pots in my 1966 mustang, they are supposed to be 250k audio pots and indeed they do say they are CTS 250k audio pots but the volume pot is 320k and the tone pot 290k, thats a difference of 70k and 40k and in a guitar that not a great deal but in a big muff tolerances that vary that much will drastically change the sound of any muff. I’m not saying big muffs tolerances vary this much, in fact i highly doubt it but they dont need to vary this much to change the sound in this pedal either. even 5-10k either way will change things. And I havent even mention capacitors and transistors yet!

I have a muff,I think its my 3034 big muff, that should have 3x100k pots, yet one is 90k one is 100k and one is 125k, them tolerances aren’t tight!

I built one from spare parts I had lying around and it sounds exactly like a couple of ramsheads I’ve used.
The 10uF input cap version is the best version to build IMO! its thicker than the other versions, you’ll have to refer to the schematic to find out which version it is if you’re using GGG.

10uF input cap ramshead version for sure…its way thicker than any other ramshead or triangle muff!

Yea it all looks fine to me too!

Its an opamp big muff you have there too, one of the best IMO. you can adjust the tone and sustain by swapping/removing resistors of certain values if it dont sound quite right.

Looks are irrelevant in tight and awkward pedals, put them between the in/out jacks maybe.

I wouldn’t be making aesthetic mods to older green/black sovteks in the first place. I mod the circuits to every sovtek i own cause i hate the sound of them but they look stock.They look cool but sound like shit stock IMO.

One of my sovteks is a ramshead muff (sounds spot on to ones I’ve heard too) and one is waiting to be modded into a ramshead, the green tank like one with the cast enclosure.

Dunno, my IC and 3034 passes unity pretty well in normal mode, they both have tone bypass so that will ALWAYS make them pass unity by a mile too. Its the passive tonestack that eats up the volume, it has a tone recovery stage but I dont think its quite good enough TBH.
