This is one very old big Muff (lotsa photos)

Friend of mine dug this out a while back and I eventually photo'd it and have finally loaded them up for your perusal. This looks like the real deal and may even be from the first issue what with the circuit board number. Anybody able to shed some light on this.









Next time I'm down his way I'll try and copy out a schematic and get what measurements I can without pulling anything out.

Thats a funky electro in there. What are the transistors? 5088?

Looks like a Sovtek to me - definitely not EH.

this one is looking soooo lovely

Yo

  Yeah. Sovtek Big Muff. Not old really. Just beat up. The schems are out there. Probably no need to trace or measure anything.

can you read the code on the transistors?

Hi.Cool!!!This is Russian muff and tranzistors here are KT3102(NPN,Hi-gain).

I don't think an early muff wouldn't have the quasi-ribbon cabling or the plastic board-mount jacks, and the traces would be curvey, not straight with right angles. So Sovtek it is. I've never seen one with the separate mounting plate like that, though.

Very standard chassis construction for Sovtek Big Muffs up until the last of the green ones.  The early ones would have the secured ribbon cables.

Still, looks like something worth playing through!

Well it shows you how much I know about commercial pedals. What I thought was a very old EH is just a reasonable old russian but I had to dig the almost archaic methods of construction, the over building as it were. I'll go hunt a schematic then 'cause it was really confusing trying to work through it. If I remember correctly it had NPN's with the collector to ground and a positive ground... weird.
