This is a 73-75 Paperface DIY Homebuilt from Jon Nensen of The Human Comparator fame… a legitimate reissue of some of the original Serge modules from 73-75.
These modules are some of my absolute favorites to play music with, as they can’t help but encourage exploration, and more often than not, that exploration is rewarding.
Seen here are some mods that I have undertaken, mostly to either add visual feedback, or switches for enabling self-cycling of envelope generators and slews, as well as switches to cascade the three stages of the triple waveshaper.
