The last layout for a while, I honesly don't know when the next one will be uploaded, probably in january. There is three eye surgeries on the horizon...
Anyway, I had athe change to trace an old EHX Muff Fuzz of the op amp variety a few weeks ago. As you know, EHX used parts whatever they had on hand in the 70s so there is lots of different schematics online so I have included several options for some of the values.
My unit had a 1458 op amp, silicon diodes, 47nF for C1 and 100k for R7.
