Pedal steel copedent
The E9 · vintage student 3+1 copedent
10 strings · 3 pedals · 1 knee lever
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.
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♯
Right knee
Levers by your right knee
- RKR 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♭
Usually not used together
- A pedal + C pedal
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.
| Str | Open | A | B | C | RKR |
|---|---|---|---|---|---|
| 1 | F♯4 | no change | no change | no change | no change |
| 2 | D♯4 | no change | no change | no change | no change |
| 3 | G♯4 | no change | ↑A+1 | no change | no change |
| 4 | E4 | no change | no change | ↑F♯+2 | ↓E♭−1 |
| 5 | B3 | ↑C♯+2 | no change | ↑C♯+2 | no change |
| 6 | G♯3 | no change | ↑A+1 | no change | no change |
| 7 | F♯3 | no change | no change | no change | no change |
| 8 | E3 | no change | no change | no change | ↓E♭−1 |
| 9 | D3 | no change | no change | no change | no change |
| 10 | B2 | ↑C♯+2 | no change | no change | no change |
+1 = a half step, +2 = a whole step.
How it differs from standard E9
- No E→F lever (E→F) — LKL on standard E9
- RKR makes the E→E♭ lever change (E→E♭) — LKR on 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
