E maj7b5 — E9 Pedal Steel
E maj7b5 has no bar or slant position on the E9 Pedal Steel with the pedals up.
E maj7b5 stacks E – G# – Bb – D#, 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 the nut spells it — one change is the fewest it takes, and the copedent page lists every position, 8 in all.
