The Musicnomad MN206 Cradle Cube is an excellent addition to any musician's workbench or kitchen table. This soft, gel-covered block supports the guitar neck while changing strings. Five different angles work for many instruments besides guitar, including mandolins, ukes, and violins. Additionally, the lip on each side holds strings away from the fretboard as needed. An excellent tool for seasoned repair techs and do-it-yourself-ers alike.
