I DO get kinda tired of defending my use of capos, for open strings, sustain, guitar-friendly keys, mock open tunings with altered capos (much described alsewhere on the 'Cat) and so on, but somebody mentioned Kysers. I've got several, all cut for altered tunings, but I still find the handle difficult to use as it faces away from the player. A similar capo with an easier handle is made by Dunlop, and I use it when I need a full capo. It's not as fine-tunable as the Schubb, but works well nonetheless. It is also a better choice (IMHO) to recommend to student players, as it requires no tinkering.

Paige and Golden Gate capos are also secure devices and easy to adapt for various tunings, but often need their padding adapted so they don't scatch the back of the neck. Leather works well. The Kyser string rubber is also the best to retro-fit most capos except the Shubb, which has the best string rubber.

Having said all this, the Shubb is still my most used full capo.

Peace, Mooh.
