This is kinda a stupid question, but I was wondering what that black round thing that seems to come with all MXR pedals is for? I have a Smart Gate but I got it used so I don't have one. Is it just to cover the knobs so you don't accidentally turn them?
Protects the knob from scuffs, also can allow you to tweak the knob with your foot while playing. You can buy them for a few bucks.
