The Planet Waves NS Cradle Capo was co-designed with Ned Steinberger to provide stable fret barring for a musician playing a 6-string acoustic or electric guitar in recording sessions, live performances, rehearsals, and lessons. It features stainless steel construction for long-lasting toughness and reliability. The self-centering cradle and adjustable micrometer enable quick and precise variation of the tension, making it ideal for use with a multitude of instrument setups. When not in use, the NS Cradle Capo can be stored above the nut whether your guitar is in or out of its case.
