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.
Good luck! You've definitely left more than enough layouts to work on until January. Thanks for all the hard work!
ReplyDeleteI hope everything goes well and wish you a fast recovery!

ReplyDeleteWish you a speedy recovery! Thanks for everything you do for this community!
ReplyDeleteThis Muff is verified is anyone fancies building. Used a 500K trimmer for R7, 10n for C1 and silicon diodes. Sounds good and very loud.
ReplyDeleteHow does it sound compared to the normal op amp muff? I'm guessing it's kinda like a one knob muff since there's no drive and tone stack, and I assume only a pair of diodes compared to the op amps 6 otherwise volume drop would have neen too much.
ReplyDeleteIts probably closer to a DOD 250 than a Muff
DeleteYou weren't kidding.... The circuit layouts are very very close.
