I've had a particular working split on my Williams 700 U12 E9/B6 for quite some time. Somewhere along the way something must have changed because today when I went for it, it was way out of tune and now it seems incapable of being tuned as currently configured. I'm aware of the tuning procedure for splits and have done it many times (but not needed very often as the axe just sits in my studio).

This is on the 6th string (G#) with the usual B pedal raise to A, and a lever lowering to F#. The split wants to produce a G.

Tuning the pedal (rod) and lever (split screw) work fine, but tuning the split (rod) down to the G is causing the open string to go sharp. IOW, shortening the lower rod is somehow forcing the open string sharp. New strings made no difference.

This is making my head spin a bit trying to imagine why this happens, especially when it didn't used to be this way and I've made no other changes to the instrument since last having tuned that split without issue.

Any ideas?

Thanks,

- Slim

Mickey Adams has an excellent YouTube video in detail of split tuning

I haven't looked at Tom's YouTube link, but the way you tell it sounds like you've been trying to tune the full lever lower to F# before the split G instead of after.

Great choice of guitar, btw!

Thanks Ian, but that's not it in this case. I've actually tried it both ways -- same problem. I think Jon Light's post that Tom pointed to above on overtuning is probably the key, although I've no idea how this could have crept up on me without having changed anything. I'll be working on the axe today...

And yes, love the guitar -- yours looks mighty pretty too!

I had a similar problem. To fix it, I loosened all the rods, retuned the string, and started retuning the rods from scratch. First the raise, then the split with the regular lowering rod, and finally yhe lower, with the split screw.

It works fine now.

Thanks for the suggestion Mike. Actually that was the first thing I tried (and have tried several times since). But as soon as I tune the split with the lowering rod, the open string goes sharp. So, time to put it on the bench and try and give the rod some more play as described in Jon's 'overtuning' post...

Solved! I was able to get closer by changing the pivot points to achieve more pull for the same lever travel. However, that didn't quite get me there and didn't explain why this used to work (until one day it didn't). I finally noticed that one of the 2 screws anchoring the base of the lever to the body had come loose, making the lever less effective. Tightening that screw fixed it.

Thanks for all the suggestions, learned a few things in the process Smile.

Hmm. Not one, but two screws loose.

You know, there's a joke in there somewhere!

Laughing

Glad you got it fixed.

Maybe Jon needs to add that to his most excellent post about overtuning.
