Ab Dominant Seventh Suspended Fourth chord (Ab7sus4) on the guitar fretboard

The Ab Dominant Seventh Suspended Fourth chord (Ab7sus4) is made of Ab (the root), Db (perfect fourth), Eb (perfect fifth) and Gb (minor seventh). The fretboard shows every one of them across the neck in standard tuning (E A D G B E), and plays them back so you can hear the chord.

This chord takes the dominant seventh and swaps its third for a fourth. That leaves a suspended fourth with a minor seventh on top. On the neck it overlaps with the shapes of its two parents, the suspended fourth and the dominant seventh.
