Big Muff early 1968-71 handwired version

I was interested to hear how the first Big Muff sounded, so I drew up this layout from the schematic of the first hand wired versions that was made around 1968-1971. It doesn't have as much gain or volume as a modern Big Muff, but it sounds excellent, much more articulate. I found the schematic on Kit Rae's excellent Big Muff PI home page here.
