A capo, or capotasto, is used on a guitar neck to shorten the strings, and therefore change the key that the guitar is played in.

They are simple to use and fit, cheap, and great for experimenting with.

If you're after a cheap capo, then we have a choice from Jim Dunlop or Planet Waves that are excellent value.

For professional use, then Shubb, Kyser and G7th have been making quality Capo's for many years.

For something a little different, try the Spider Capo or the Glider Capo.
