Yep, RF was right on with his suggestion. (Damn, I miss him around here)

I use a Shubb for studio work because of the adjustment ability, but a Kyser most of the rest of the time because of the convenience. Most of the problems with throwing the guitar out of tune can be worked out with a good set-up; obviously a high action will compound things. I might have to tweak my low E and B strings a bit sometimes when they get a bit older, but it's no great hardship. When not in use, it's clamped on the headstock--where it helps with the sustain, don'tchaknow?   ;)   

I've never found the Kyser to get in the way at all and I quite like the looks of it. I had the spring blow in my first one after a few years, but I have 2 more and they are holding up well. They get a LOT of use, sometimes up to the 8th or 9th fret.

The Shubb is the one I use the few times I use a capo on my mandolin. Yeah, I do use one there sometimes, when the song is in Eb, or Ab or F#....
