Open strings and root positions

3 of the 8 open strings belong to Ab Diminished 7 Arpeggio: string 7 Cb (b3), string 4 Ebb (b5), and string 2 Cb (b3). None of those open-string tones is the Ab root, so the root must be fretted on every string.

Practice this tuning-specific layout

Play Ab Diminished 7 Arpeggio on the low E string at frets 1, 4, 7, and 10, saying each note name and degree aloud.
Build a phrase that lets Cb on open string 7 ring, then connect it to the nearest Ab root and two other arpeggio tones.
Connect the Ab root positions on strings 8 through 1 at frets 4, 9, 4, 11, 6, 1, 9, and 4, adding the nearest arpeggio tone between each pair of roots.
