Pedal Steel Atlas

Pedal steel copedent

The E9 · 3+2 minimal copedent

10 strings · 3 pedals · 2 knee levers

A copedent is the map of what each pedal and knee lever does to each string. Players set theirs up differently, so if you’re not sure what yours is, press each pedal and lever one at a time and listen for which strings move — then compare with the chart below.

Where everything is — and what it does

Pedals sit under your left foot; knee levers hang under the guitar where your knees push them. Colors match the app and the chart below.

Left knee

Levers by your left knee

  • LKL E→F lever

    Push your knee to the left

    Raises your E strings (4 & 8) a half step to F.

    • String 4 E → F
    • String 8 E → F
  • LKR E→E♭ lever

    Push your knee to the right

    Lowers your E strings (4 & 8) a half step to E♭.

    • String 4 E → E♭
    • String 8 E → E♭

Pedals

Under your left foot, left to right

  • A A pedal

    Press with your left foot

    Raises your B strings (5 & 10) a whole step to C♯.

    • String 5 B → C♯
    • String 10 B → C♯
  • B B pedal

    Press with your left foot

    Raises your G♯ strings (3 & 6) a half step to A.

    • String 3 G♯ → A
    • String 6 G♯ → A
  • C C pedal

    Press with your left foot

    Raises string 4 (E) to F♯ and string 5 (B) to C♯ — a whole step each.

    • String 4 E → F♯
    • String 5 B → C♯

Usually not used together

  • A pedal + C pedal

One at a time (same knee)

  • E→F lever or E→E♭ lever

Copedent chart

Strings run top to bottom — string 1 is farthest from you. Each column shows the note a string moves to when that pedal or lever is engaged.

How it differs from standard E9

  • No F♯ & D♯ raise lever (F♯→G♯ + D♯→E + G♯→F♯) — RKL on standard E9
  • No D lever (D, then C♯ with string 9) — RKR on standard E9
