D# aug7 — E9 Pedal Steel
D# aug7 has no bar or slant position on the E9 Pedal Steel with the pedals up.
D# aug7 stacks D# – F## – A## – C#, and with every pedal up and every lever at rest no bar position on the E9 Pedal Steel sounds that set: at every fret, and on every short slant, a tone it needs is missing or too few strings carry it.
A pedal steel does not stop there. With LKV engaged, a straight bar at fret 5 spells it — one change is the fewest it takes, and the copedent page lists every position, 12 in all.
