This is the H.W. Cano Electronics Quantum - Discrete Distortion! It's from 1983, probably based off the classic FZ-1 / MK1 circuits (this is still up for debate), and sounds like a buzzsaw tearing into a steel wall...
I've only seen one other unit before, of course on the effects database site, and that one was made on the same day and numbered 007. So as of now I don't have much (if any) information on these, like how many were made, but I do know they were from the mind of electronics wizard, Howard Cano.
To do a full posting on this I need to keep digging up any available info on Cano's history and audio electronics career (including drum synths and midi-conversion kits), so if you happen to have more details definitely reach out to me either through email or instagram.
Thanks for reading!-ed
