A 13b9 — C6 Pedal Steel

A 13b9 stacks A – Bb – C# – E – F# – G, and with every pedal up and every lever at rest no bar position on the C6 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 Pedal 5 + Pedal 6 engaged, a straight bar at fret 1 spells it — 2 changes is the fewest it takes, and the copedent page lists every position, 6 in all.
