The BeachBoys PetSound DVD-A on the ‘God Only Knows’ studio-take track, the bassist hit the pickup(s) while playing a note and there’s this very loud subsonic thump that really shakes the room. It’s kinda of cool because it only happens once … I can see it being annoying if it happens on every other bar, though.
