GLOW IN THE DARK KNOB RINGS!!!!!!! My world is now complete.
As far as punching thru anything other than my patience, they're talking about their speech compressor that's pictured underneath the glowing c rings.
If you've ever heard one on the air, it's like talking thru a kazoo hooked up to a 10kW PA head connected to bullhorns that have been fashioned into headphones.
"Piercing" doesn't quite describe it.
