The Shubb Partial Kapodaster C7B skips the outside string and covers the next three, either 2-3-4 or 5-4-3.
The capo is attached without spring or clamping mechanism. The patented locking action provides an unrivaled combination of power, speed, accuracy and ease of usability. The elevating screw provides a constant pressure to the strings. 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!
