Zeugma (Zonk Machine MKI)

[Guilherme Collateral]

What a finicky circuit to build, I hate every second of testing transistors for Zonks and MKI. There is no magic formula to follow, gotta socket and try infinite combos to find the sweetspot between gain, sustain and gate. But when it sounds good, oh boy, does it sound good! Went full mojo on this one, 0.15” pitch Vero, carbon comp (for the values I had on Stock), Philips capacitors and Mullard OC44/71 and GET873. Got weird noises on the decay but got rid of it with a 1nf cap between input and ground. Very inspiring Fuzz, I even recorded a little video of it!

This is not fair…. @Guilherme Collateral can make fabulous pedals and fantastic demos!

Love the toan on this pedal. I may have to give this circuit a go.

Yet another inspiring build from @Guilherme Collateral (and some inspiring playing, too)! Did you happen to record the gain/leakage/collector voltages for the transistors?

Lovely!

Question about these threaded inserts - what are they? Self clinching rivet nuts?

Excellent. Time to learn some riffs by The Plastic Clouds…

My guess is spot-welded.

Ahaha thanks man! I don’t know about fantastic demos but I’m trying to improve it.

Thanks man! I’ll pull the transistors and measure them, but from the top of my mind I remember Q3 (the GET873) being hFE = 79 and leakage 0.03

Thanks buddy! I don’t really know how it’s done, but I got this enclosure from @mwpedalparts-maggie ! Really great quality stuff

First I need to learn what is/who are The Plastic Clouds
