Clicking the big dial

I scrambled across the rug to investigate the heavy metal box sitting low by the shelf! It had a giant round dial jutting out from its brushed silver face. I braced my feet against the warm casing and shoved the grooved knob with my whole shoulder. *Click!* Oh, that crisp mechanical snap felt incredible! I leaned hard the other way—*click-click-click!* Tiny tactile notches pulsed straight through my paws, ratcheting with the sharpest little percussion rhythm. The metallic vibration buzzed through the entire chassis! I found my new tempo dial!
