Thanks a lot man! Ahahaha that battery always draws attention when I show it on pictures. It’s a really cheap Chinese battery that comes in lots of Brazilian toys, but they are the Carbon kind, so it’s kind of a Mojo thing
There is a LOT of info about this circuit condensed here, https://vero-p2p.blogspot.com/2022/12/zonk-machine-component-values-table.html
And this is a rare case of a pedal which isn’t really “paint by numbers”. I tried to make one using different brand transistors with the same hFE/leakage for...
Hey @Mark, the enclosure is from @mwpedalparts-maggie, really great stuff. The artwork is silk screened to the enclosure. As for the transistors, it doesn’t really exist a formula (as you can see from the wide range of gain/hFE used on originals). You need to have the sound on your head and swap...
I really recommend it! But don’t use a transistor pair you would use in a fuzz face, it needs lots of leakage to sound as a real deal MKI.5. You want low gain and high leakage! Check the voltages online
