Pyrite Fuzz - courtesy of @Ginsly with PCB designed by @PedalBuilder.

I really like the mark III Tone Bender and have built a couple with one off transistors I got my hands on. So I did the thing many developing DIY pedal builders do and bought a box of magic beans from Eastern Europe on E Bay. I think they came on a boat. Opening a sealed Soviet era box of transistors was interesting its own right but the gains were super low from about 17 below 37 on the samples i tested. I was not shocked but was a little disappointed so they went on the shelf well I kept an eye for a suitable circuit.

So when I saw @Ginsly post his Pyrite saga I had to reach out.

This is my test build (1 of 3). I’m glad I used sockets on the first one and learned to read soviet schematics. I had a to do a little leg cross but I think it looks classy.

- No Charge pump
- Runs on Magic Beans
- Fuzzes like a mother
- Easy build
- Does the germanium harmonic/ kinda gated fuzzy thing I like really well.
- Low Depth settings are where the moneys at

I think the name @Ginsly came up with this is perfect considering its FuzzRite lineage and back story. If you havent already - check out his thread

@Ginsly @PedalBuilder - Thank you and Respect!!

Hey, nice build! I missed the original report for this board, so thanks for keeping the discussion going. The way the magic beans 🫘 are posed makes them look like they just finished a musical number and are taking their curtain call. And the whole thing looks like it should come with a lead content warning, which I think means it has The Mojo.

Btw, if you want a cheap-ish “anvil” for your lettering stamps, I recommend grabbing a cheap pair of 1-2-3 blocks on Amazon or whatever. Should be about $20 and make sure you get the ones without holes. They’re useful for all kinds of things outside of stamping as well. If you went for that “weathered” look intentionally, please forgive my Dan-splaining.
 
@Band of Dans - are you suggesting I could improve upon my wooden anvil 😂

Hey, that’s actually a pretty sweet setup!

There’s some amount of dimpling that just can’t be avoided, but I second what @Band of Dans said- a pair of solid 1/2/3 blocks is what I used when I pummeled Pyrite #1 (below), and although it still has uh, character, the blocks really did help keep the top from caving in too much. You just have to keep moving them around as you go since they don’t fill up the entire body like your anvil! :)
