Kyser Quick-Change Acoustic Capo The first. The fastest. The Original. Kyser® Quick-Change® acoustic guitar capos changed everything when they hit the clubs of Deep Ellum, Texas in the 1980s, and they’re still the quickest capos in the West, coveted by the biggest artists on the world's biggest stages. The unique trigger mechanism never misfires, offering precise, reliable tuning that’s always dead-on. Stick it on whatever fret you’d like and it stays where it should, or leave it on the headstock ‘til you need it. Your Kyser keeps close.
