Shubb Standard Capo for Western guitar - nickel

On the original Shubb capo, the dropoff increases at the smallest end of the capo's range, and decreases at its widest end. In other words, when used on an very thin guitar neck, the dropoff effect is exaggerated. In the extreme, it could result in insufficient pressure on the strings when engaged. On an unusually thick neck, the dropoff is minimal. In the extreme, it could result in an insecure lock, or too much pressure on the strings when engaged.
