Open strings and root positions

1 of the 6 open strings belong to Ab Phrygian Scale: string 2 Bbb (b2). 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 Phrygian Scale on the low C string at frets 1, 3, 4, 6, 8, 9, and 11, saying each note name and degree aloud.
Build a phrase that lets Bbb on open string 2 ring, then connect it to the nearest Ab root and two other scale tones.
Connect the Ab root positions on strings 6 through 1 at frets 8, 1, 8, 3, 11, and 6, adding the nearest scale tone between each pair of roots.
