About the G flat Diminished scale
G flat Diminished is used for jazz solos over diminished chords and tense, suspenseful film cues. Think of it as a symmetrical eight-note scale that alternates whole and half steps. It is G♭ Bebop Melodic Minor with the fifth lowered.
Its notes are G♭, A♭, A, C♭, C, D, E♭, and F. The formula is W H W H W H W H.
Also called Diminished Whole-Half and Octatonic.
A, D, and B are open guitar strings that sit inside this mode, ready to drone under a riff. A guitarist finds the lowest G♭ at the 2nd fret of the low E string. A capo at the second fret brings G♭ Diminished within reach of E-shape fingerings.

8-position system
8 four-fret boxes, one per scale degree, each a single hand position with almost no shifting. The jazz and classical way, from William Leavitt's Berklee method. This scale is symmetric, so the same box shape repeats up the neck.
