Made this one for a US based customer! Used a trio of MP20B

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...

This looks really good, great work!

Looks like an Ibanez Artcore

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

I’ve been building pedals for almost 20 years and for some reason I never built any MKII with AC128! I’ll try it this week

Thanks a lot man! Glad you liked it 🫶

That faceplate looks sweet (pun intended, but also true)

Yeah, like everyone said, that’s a very impressive 3rd build, congrats! This is a really good sounding pedal indeed!

I’ll record something later, but the transistors read really close to the real deal, Q1 hFE 33, leakage close to 0, q2 hFE 55, leakage in the 80-100s, Q3 hFE 200, leakage around 180 (all measured yesterday, a cold day around here)

Here is another mojo-tastic build. Used a pair of Tungsram AC128 for this - I hate this transistor on Fuzz Faces, but sounds great on a I.5! And a short video showing its clean up:

I made a project for a smaller sized wedge enclosure with the jacks on the same profile as the other hardware and board goes, because I was always annoyed with wiring floating between the two parts of the regular Bender/Zonk enclosure. For the circuit I used a vintage specs stripboard I got made...

Thanks a lot man! And I’m not as brave as you with the PTP builds, your projects are insane!

Thanks man !

That’s awesome! ✌️✌️ I’ve been cooking the idea for a Profondo Rosso pedal for years!

That looks really cool, and it’s nice to find another Giallo fan around here!

Sounds great man, good job! Gotta love the Zonk tones

Thank you! It’s indeed a 1590xx

Thanks a lot man! ✌️✌️
