With “Bass mod” by Aion Electronics. Original has internal DIP switches to select different bass frequencies but is here moved to the outside and converted to a pot.
Univox/Shin Ei UD-50 Uni Drive w Aion “Monad” mods
This one has been modified for regular stompbox use and more useful controls. Also a feedback trimpot has been added to achieve more gain on tap. Aion’s Monad projects suggest a 10k trimpot but I suggest a much larger value to be able to turn it into a heavy high gain fuzz.
