G maj7#5 — E9 Pedal Steel
G maj7#5 has no bar or slant position on the E9 Pedal Steel with the pedals up.
G maj7#5 stacks G – B – D# – F#, 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 A pedal + LKV engaged, a straight bar at fret 3 spells it — 2 changes is the fewest it takes, and the copedent page lists every position, 8 in all.
