Guitar maintenance is just as critical to an instrument’s sound and playability as a new set of strings. Clean, smooth frets allow for optimal contact of the strings to your instrument, improving the instrument’s sound and playability. The GHS Fingerboard Care Kit makes it easy to maintain your instrument’s frets and fingerboard.The kit is ideal for all stringed instruments with natural, non-glossy, darker fingerboards. This includes acoustic, electric, classical and bass guitars as well as ukuleles and other fretted instruments.
