A pal showed me a trick with a Kyser capo last week: put it on back to front and it's a partial capo covering three strings. So it can turn standard tuning into a pre-populated A chord if you want or what he did was to use it on strings 3, 4 & 5 at the second fret to make it into an Esus4 chord, so sort of DADGAD-ish but up a tone like Sonny Walkman has posted above.

Kysers (and others) can also be used upside down on strings 1 to 5 at the second fret so it's a sort of drop-D but shapes like G chords are still conventional.
