G#sus4/D# (Guitar, Intermediate)

The chord illustrated above is actually the second inversion of the G# suspended-4th chord, as the perfect fifth (D#) is the bass note of the voicing:

A string: D# (perfect 5th)
D string: G# (root)
G string: C# (suspended 4th)
B string: D# (perfect 5th)

But to clarify that it is a certain chord with a non-root bass note, we use the slash-note designation: G#sus4/D#.
