On Stage GS7800 Mic Stand Guitar Hanger

Onstage says:

Keep your guitar close! Hang it from your microphone stand. The GS7800 takes advantage of the patent-pending u-mount clamp and lets your existing mic stand pull double duty as a guitar stand. The easy-on, easy-off single knob clamp secures to any shaft up to ¾” in diameter. Your guitar will always be in reach and your piece of the stage will be clutter-free. The swivel yoke fits most conventional headstocks and is lined with inert velveteen foam. An exclusive EVA bumper is included to stabilize and protect your electric or acoustic guitar.
