First time seeing a partial capo in use

[poodlesrule]

Local folk songwriter was playing at a small gig last night. I was close to the stage and noticed the use of a partial capo. Never seen one before.
Cool, and kind of funny at first to see someone fretting*behind* as well as in front of capo!

Wikipedia tells me their use is rather new.

I think Phil Keaggy used to put in his liner notes how he tuned for some songs, like where he would take a capo and cut out part of it to keep some strings un-capoed. But it does seem like they are becoming more commonplace.

David Wilcox does some very useful stuff with those, and when I saw him, he even used 2 capos at once. I haven't a clue how somebody can deal with so many variables.

Kyser makes several partial capos to give you specific tunings without needing to retune your guitar and keep standard fingering patterns for chords. The guy doing the demo at the guitar show was quite knowledgeable about their use.
