Bobby Lee's Custom D13th Universal Tuning with GHS Strings Custom 12-String Set

Bobby Lee's Custom GHS D13th Universal 12-String Set

Johnny Cox developed the D13th copedent as a universal with all of the changes from a standard double neck D-10. The E9th tuning is lowered to D9th, and the C6th tuning is raised to D6th. This gives both a common root note - D.

The basic idea can be adapted to most standard U-12 pedal steels as shown below. The right knee right (RKR) lever lowers the 10th and 11th strings to get the bass note inversions of the C6th tuning.

We package these sets here at The Steel Guitar Shopper offices (Steel Guitar Forum store) to support a small but growing list of enthusiasts.
