Finally, a professional string dampener/ muting accessory that every studio, session player, and tapping aficionado should have! Slide on a fret wrap to effectively cut overtones and sympathetic resonance during recording, live performance, two-hand tapping, or any creative situation where you need that extra muting hand for cleaner takes without the unwanted string noise or ringing. The adjustable strap lets you fine-tune the pressure and dampening of the strings. Quickly slides over the headstock when not in use. No special guitar modification, installation, or tools required – yet amazingly effective!
