Hello, the Glider capo is the best capo I've ever owned. Only problem is that it doesn't work too well on 12-strings, probably because it can't hit all of the strings, but I thought you'd want to know about it. It's ideal for switching keys in the middle of a song, such as in He Stopped Loving Her Today or She's Actin' Single, I'm Drinkin' Doubles. In both of those songs, the key change would require a double-necked guitar (those do exist by the way,) with capos on different frets on each of the necks, or the use of hard bar chords. The reason is because instead of certain songs changing from the key of C to the key of D, for instance, the song would change from C to C sharp. This way, you just roll the capo along the fret board. Go to

and type in glider capo in the search box. Can't think of any Gord songs that use a key change of a half step so that it would be hard to play though. Enjoy, and let me know if you enjoy the capo as much as I do.
