I have big, clumsy, oafish feet. 3 switches on a vertical 1590BB could spell hours of humiliation and diappointment for them... But I would likely still buy one. As much as I like footswitchable modulation, perhaps for a smaller enclosure the modulation footswitch could be moved to a toggle?
Anyway you do it, I'm sure you'll come up with something very useable and awesome.

Also, I don't really care how you decorate the box, because your pedals are obviously very well designed, and you jam an incredible amount of awesome features and great sounds into your pedals.
But yeah, pretty things catch my attention
