the one thing i noticed with the original Shubb & i am uncertain if the concern has been
addressed in a more current version or revision, as the capo i bought was around 02-03,
but on a Rainsong WS1000, it would not hold adequate tension to be used on the first fret &
with the tension adjustment max'd out, there was insufficient travel to be used effectively
one could say that was due to the neck profile on the guitar, but the capo was designed for
an acoustic & i also noticed that the length of the pad or 'leg' was not quite long enough to
be used on a 12 string with 1 7/8" nut (like the G7th, there is a separate 12 string model)
otherwise, i feel the shubb works well & they also make a 'lite' model & one with a black finish,
that would make it 'nearly' invisible when used on a guitar with ebony fretboard under low light
