My Current Copedents (as of May, 2017)
2017 Sierra by Ross Shafer, S-10 D6th
In a quest for a single neck copedent that could handle almost anything, I’ve settled on this 10-string with 6 pedals and 6 knee levers. D is midway between C and E, so D6th is midway between E9th and C6th. The string order is like C6th, but all of the high intervals of the E9th are still there. The trick is that notes from the E9th string 2 are on string 4 instead.
P1 and P2 are the E9th A+B changes. LKL is the “F lever”. LKR and RKR provide the “chromatic” notes of the E9th 2nd string, which are now on the 4th string. P5 (like C6th P7) has the bounce of the E9th C pedal on the 3rd string, while LKV provides a more “squeezable” C pedal change. This copedent doesn’t have the more modern E9th changes, but there’s enough of that Nashville sound on the high strings to satisfy real country music fans.
Everything from Buddy Emmons’ C6th is there (raised a step to D6th) except for the 8th string raise of the standard C6th P4. I raise the 9th string instead on LKR to get the alternating bass on the D chord.
I use LKV when I’m playing E9th-like stuff, and LKV2 when I’m deep into C6th mode. The one that I’m not using is pulled out of the way. The change in parens is rodded for country/folk/rock but backed out when I’m playing more swing tunes.
I call this copedent D6/G (D6th over G). It gives me the basic features of the standard E9th and C6th tunings in a smaller, simpler instrument. Most builders stopped making 8 string pedal steels in the early 1960’s, before the changer mechanisms had matured enough to handle a triple-raise, double lower copedent. My Desert Rose S-8 was custom-built in 2009 by Chuck Back to support this unusual hybrid tuning.
Pedals 1 and 2 combine with LKL and LKV to emulate the basic country E9th sound, tuned one step lower. Pedals 3, 4, 5 and all of the levers except LKV are standard C6th changes, tuned one step higher. As a bonus, holding down p2 makes a G major which includes all of the notes of the standard dobro tuning.
I use an electronic tuner to fine tune the notes in meantone temperament for smoother harmonies. My tuner offsets (in cents) are: D# -12.5, G# -10, C# -7.5, F# -5, B -2.5, E 0, A +2.5, D +5, G +7.5, C +10, F +12.5. See the pattern?
You can hear this D6/G copedent in my Wine Country Swing recordings on Soundcloud.
I use a Carter D-10 for teaching and occasionally for recording. This instrument was built with 8 pedals and 5 knee levers (I added the LKL2). It was one of the last Carters produced. The beautiful sunburst body was finished by Mark Giles, and the guitar was built in Canada by Al Brisco. It has the 4 raise, 2 lower changer that was typical of late model Carters.
I don’t like half-stop knee levers, so I lower the 2nd string D# to C# on the 1st pedal instead. This also allows me to use it with the E lowers (RKL) for pentatonic blues riffs. To me, having the standard A B C pedals on P2, P3 and P4 is more comfortable ergonomically.
This guitar has tunable splits, which means that I can combine LKR and P3 to get a tunable G note on the middle G#, or combine LKV with P2 or P4 for a tunable C note on the middle B string. Tunable splits are a feature that you don’t find on older steel guitars.
The back neck is tuned to D6th, a step higher than the standard C6th, to match my Desert Rose S-8. The standard back neck P4 changes are missing – the pedal would have been too stiff with the addition of the E9th changes. Instead, I added a single half-step raise in the middle F#. This gives me the open strings of the Dobro G tuning for bluegrass hammer-ons and pull-offs.
