Hey folks,
Sorry if this has already been addressed elsewhere.
I've got an Emmons P/P SD10, E9. Standard Emmons E's on the left. RKL raises string 1 a whole tone, string 2 a semitone, and lowers string 6 a whole tone. Here's my curiosity.
Let's imagine I'm playing an A chord in open position with AB down on strings 6,7,8. There's a nice major 7 thing I've been grabbing by striking string 1 (F# - making an A6) and engaging RKL (F# > G# - up to an Amaj7). When I do this on my Emmons, the A on string 6 isn't affected by my RKL.
On my all pull guitars, the combination of B and RKL results in a reliably out of tune split, so I obviously just don't use them in combination. Whereas on the P/P, it's like the B pedal change sort of overrides the RKL change.
Any thoughts on how to sort out an all pull to react this way?
Another interesting feature of it being setup this way is that with RKL engaged and the G# lowered to an F#, the B pedal effectively raises and lowers the 6th string 3 semitones. Lots of interesting sus movements available.
I welcome your thoughts and sage wisdom

You would need an additional pull rod on the B pedal for the 6th string to duplicate the lower of your RKL and then readjust the original raise rod on the same string to overcome the lowering and reach the correct note so it sounds like a halfstep raise.
Also possible to make some mechanical linkage that will effectivly disengage the RKL lower on the 6th string when the B pedal is pressed but it would require a handful custom made parts.

On an all pull guitar you can get a "perfect" split with the B pedal raise and lowering it a full tone with a knee lever.
There are two ways to do this and yours apparently does not have the "split tuning" at the changer end (a screw to adjust the full drop finger stop) like many guitars have. The other way is with an additional rod to adjust it for a perfect split.
I have adjustment screws on my Franklin for the 5th and 6th strings to get "perfect tune" splits. The 5th string with the A pedal and knee lever (LKV) that lowers the 5th string and the 6th string with the B pedal and the knee lever (RKL) that lowers the 6th string.
On an Emmons PP its doable with a knee lever that lowers the 6th string a full tone with a half tone feel stop. I had that on my 71 PP Emmons. It was installed by Johnny Cox.
FWIW my Franklin may be the only one with the split screws as I had that added by Mr. Franklin. |

Interesting…
Bengt describes how to emulate a PP's "dominant raise" on an AP. Will work fine, and sounds like that is what Matt want.
Jack describes how to emulate a specific AP change on a PP. Will also work fine, but doesn't sound like that is what Matt want. |
