Welcome to the dark side of the MOTM force. I dub thee Darth Pugix. I would Imagine that the 3/4" alco knobs would be mighty tight squeeze on that grid, though. I moved down to 1/2" knobs and they are able to fit on a slightly tighter 7/8 x 7/8 grid with tick marks. I've also been experimenting with different jack placements so I can squeeze them closer toghether as seen on my 2U doomsday machine with 20 jacks and 18 pots.
