For over 40 years, the Shubb Capo has been the capo of choice nearly everyone (check their artist roster here).
Shubb's basic mechanical principle, though tweaked slightly over the years, remains the same: a unique over-center locking mechanism that provides an unrivaled combination of power, speed, accuracy and ease of use. One smooth flip of the lever locks it securely in place, and removes it just as quickly.
And the Shubb capo is BY FAR the best at not creating 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. Its closing action is just like your hand, so it doesn’t pull the string off center. As a result, no re-tuning is necessary!
For Banjo (also fits mandolin and bouzouki). 1.5" wide.
