Review: GM Dobro, Squareneck, or Hawaiian Guitar Capo

A customer of mine was interested in slapping a capo on his raised-string Hawaiian guitars and lap steels and I started hunting for a design that could work for anything. I have to say that it's actually really hard to find ones that are universal and easily-fit. This GM capo works beautifully, however, due to its reversible mounting (brass capo-nut fits either above or below the strings).
