Shubb SC6B Dobro Capo

Unlike other Dobro capos that attach only to the strings, the Shubb clamps solidly to the neck to provide great tone. It uses the same patented locking action of our Shubb guitar capo, and it aligns by touching the fret, not by eye, making it fast and accurate.

This is the best capo ever put on a resophonic guitar. 
It is NOT for use on Weissenborn style guitars with hollow necks, because their necks are too deep and too fragile.
