Split Tuning NOT in Changer Housing?
Can splits be tuned if the changer housing is not drilled & tapped?
I have seen photos of high-end guitars (Franklins) with changers that are NOT drilled. I would expect these steels to have every refinement.
Maybe splits can be adjusted with addition of rods and bellcranks. Can someone explain how it is done? Is the split tuned as a RAISE or LOWER adjustment? |

Most of the time if the back of the changer is not setup for splits they can still be accomplished by adding a rod from the lowering bellcrank of the change in question at the closest available place closest to the cross shaft attaching to the raise on the string in question as far from the changer axle in the raise position as possible. The reason for this particular placement is because the resulting necessary change is quite small and you would prefer not to feel it. The reason so add it to the raise side is that when the split is adjusted the resulting lower is usually too flat and must be brought back up. The proper tuning sequence must be followed:
1- adjust the open note at the keyhead
2- adjust the raised note at the changer end
3- adjust the split w both the lower and raise in question engaged using the original lowering adjusting tuning nut at the changer end and finally
4- adjust the final lower using the new split rod at the changer end.
I have seen cases where the resulting lower was too sharp and consequently the new rod wen from the raise on the bellcrank to the lower on the changer.
Frequently you can use the same bellcrank that is used for the lowering simultaneously for the new split rod as the lowering rod is generally further away from the cross shaft on the bellcrank allowing for insertion of another rod. Also required is an available raise hole in the raise scissor or some adapter must be made to allow for an additional raise. |

Here is an old drawing I recovered, not attributed, unfortunately, showing the split I used.
Hope this indeed applies.

These diagrams should be a big help in seeing how to implement the extra rod, and why it works. Charlie, your diagram is from the back of an Emmons course, I believe "Half Duzzin Shuffles" where some of Buddy's arrangements make great, and very musical, use of the splits.

| Wow, much thanks to Jim, Charlie and Mike. This is more information than I could have hoped for. Great diagrams and explanations to boot. It's finally sinking in how this works. Appreciate the replies! |
