A third-hand capo (adjustable to fit any specific string
combination on a single fret)
A 2-string capo-- either A-D strings or G-B strings (modified
from a Kyser Drop-D capo)
A 3-string capo-- either A-D-G strings or D-G-B (modified
from a Kyser Drop-D capo) [note: Kyser is now mass-producing the 3-string capo and now has a website devoted to it.]
A standard Kyser Drop-D capo
The image above is a picture of one of the capos I often use in performing as used on the guitar itself (click on it to show one of the other capos). The picture below is the collection. They allow me to do very specialized work on the guitar by fretting only a few strings at a time. By combining various capos, I can play music which has totally expanded my views on what a guitar can do, and how I can use it.
I was able to create the three-shortened capos by sawing off the end of a Kyser "Drop-D" capo. However, I also like to use a "third-hand capo" as well. Combining the third-hand capo with my own partial capos allows me to choose more complex open string configurations.
