Capos for folk instruments allow quick key changes while maintaining open-string resonance, essential for genres like bluegrass and Celtic music. Unlike standard guitar capos, folk capos are often specialized for banjos, mandolins, or ukuleles. Popular models include Shubb C5 (banjo), Kyser Quick-Change (ukulele), Paige Clik (mandolin), and G7th Newport (universal folk capo). These capos enhance playability, offering musicians a simple way to shift pitch without altering fingerings, making them useful for live performances and jamming.
