Unicord/Univox Super-FuzzVerified
Based on the Univox Super-Fuzz· 37 other boards clone it
From the post
A friend of mine was wondering about Malekko mini boxed fuzz and forums told us that the unit was apparently just Univox Super-Fuzz clone in A-box. With our favourite methods, there is not a snowball's chance in hell to fit this in A. There's already Mark's original layout in the library, but i redrew this so it can be fitted in 1590B box instead of BB.
This layout is per the factory schematic found on Univox.org. I swapped the transistor pinouts for modern ones so that 2N5088, 2N5089, MPSA18 and similar can be used. There's added anti-popping pull-down resistor at the input and a polarity protection for your convenience.
Layout is now fixed and verified. Happy building everyone!
