I've met the guy who makes this, we've played a show with his band. He has created all these small no-knob effects that you dial in with little trim pots and then just switch on and off, and he'll build any number of them into this kind of mega board to have them all together.
@bencmeissner I just read about them in Racket magazine, they look cool. There have been a few amp builders around here over the years (Eden and Savage for two), good to see some new ones coming in too.
