I got to the FF via Vulfpeck. My son hipped me to both of them. I asked him how they get that drum sound, and he told me they have a compressor they built(?) and that's what they use to get that cool no O tone tone.Love FF and Nate Smith. Check out Vulfpeck if you have a chance. They share some members amongst other things.
They're just running the cables for the guitars up those stands. Makes sure they all stand in the right places and things aren't messy.You're right the guitars are all on stands. That and the jumpsuits give it a certain vibe. I was feeling Devo when I first saw them, not musically, visually.
