Passive summing mixer

This is a custom handmade little box it’s made especially for the uad gain stage to get the most out of the uad unison plugs!
I am just not getting the use out it right now so I am moving it on.
It adds saturation depending on how hard you drive it.
I find it glued the kick and bass toghther in a really nice way that seems to resonate in a way that’s quite musical.
