Precisely machined of brass and carefully hand-assembled, a Shubb capo is manufactured without compromise. A patented locking action which provides an unrivaled combination of power, speed, accuracy and ease of use set Shubb apart from the rest. One smooth flip of the lever locks it securely in place... and removes it just as quickly. And the Shubb capo doesn't create tuning problems. Its soft, resilient rubber is specially designed to work just like a fingertip, so it doesn't bend the strings over the frets.
