This is a library of perfboard and single-sided PCB effect layouts for guitar and bass. I'm not an electrical engineer by any stretch of the imagination, just a DIY'er who likes drawing layouts. It is meant for the hobbyist (so commercial use of any of these layout is not allowed without permission) and as a way to give back to the online DIY community.

Not A Muff

Happy Fuzz Friday, all! Recently I got a request for the new EQD Hizumitas. Found a schematic for it over on FSB and it's just a BMP. The values are tweaked, but the topology is the exact same as a standard Muff. If you've hung around here for really any length of time you know how many times I've laid out the BMP. There are so many clones out there dating back to the early 70s, most of which I haven't really explored here on the blog. So using Kit Rae's fantastic Big Muff site, I put together a BOM of 6 versions of non-muffs, including the Hizumitas and the Elk Sustainar the Hizumitas is derived from. So for your building and experimenting pleasure, here's the Not A Muff. (BOM, schematic and drilling templates linked below)

Also, if you're interested in how I laid out this board, I did a livestream over on YouTube. I've been trying to do a couple streams a month of just chilling and doing some layout work in Eagle. So go and sub and all that nonsense.

    You can mark this verified. I built the hizumitas on perf with a bunch of sockets. Great work!
    There is a 100p cap to ground at the input { socketed) cant really hear ant dif if it in or out.

      Thanks for verifying! Yeah, that 100p cap is standard practice for EQD, but not always necessary, so I left it out.
