The Swift Capo is spring loaded and easily gripped, allowing you to quickly change keys on almost all fretted instruments. It provides ample tension ensuring the strings will not buzz while in use. The thick padded rubber will not scratch the back of the neck or headstock of your instrument. The brushed copper, black, and silver are richly appealing finishes that can easily blend with most fingerboards. Its smaller shape allows for easy storage in gig bags and case storage compartments. Fits Banjos, Ukuleles, Tenor Guitars, and Mandolins.
