What RichM said. Precisely. The Shubb is a better machine - it's a brilliant design - but since it doesn't clamp to the headstock, you always set it down somewhere, or put it in a pocket, and you can't find it again when you need it. On stage, this isn't good.Also, the gigs I do, if the Keyser affects the intonation a little, no one's likely to notice except me.

PS: Anyone use the Keyser "Dropped D" capo? Fun.
