No more unwanted rattling and unwanted sounds. No more socks, sweatbands and headbands on guitar heads. If you need to dampen the strings, then use the iBOX Damper made in Brazil. A string dampener will help you effectively dampen "overtones" and unwanted string resonance while playing. It will serve very well at a concert, and especially in the studio, where every unwanted sound can be heard. Each model is made so that you can determine for yourself how hard it presses the strings. Putting it on and possibly removing it from the guitar is quick and convenient.
