timing pulls for compensating rods and splits?

Nicholas Dedring · From: Beacon, New York, USA

I want to add some pulls to compensate for the 6th string drop with the A pedal, and put splits on for A&X, and for the 6th string drop to combine with the B pedal.

This all requires additional rods to balance the notes out... does this create a problem with timing? I'm just concerned that it'll make the pedal pull have a hiccup in it, pitchwise. I assume you want the compensator to start pulling at the same time as the pedal, same with the split... how do you time/balance these out?

Also, does it make more sense to add an extra lowering rod to the A pedal, or to add an extra raise to the X-lever in splitting the change? OR: is it just kind of six of one, half a dozen of the other?

Hmmmmm

Some interesting questions. Let's see....

IMO:

1. Use the "slowest" pull on string 6 when compensating it with pedal A. The reason of course, is to overcome just what you said. So how do you get the slowest pull? You use the hole closest to the axle of the bellcrank and the hole furthest from the axle in the changer.

2. For splitting A and X, Timing (of the rods) is not a problem on any guitar I have ever owned using this split. The reason for this is, the player controls the timing rather than leverage in this case. By how you engage the two opposing pulls at the same time. In fact that is one of the problems of splitting. Takes a while to get it down right; particularly for slow splits. Lest you "stepladder" the split on the way down to it; or up to it.

3. Same for lowering the G# to F# (6th string) and B pedal.

4. It depends on how close (or far) you tune to ET. IF you tune dead on ET you add an extra raise rod to the X lever. Same thing if you tune close to ET. If you tune halfway between JI and ET, it may split perfectly (or extremely close) with NO extra rods. If you tune dead on JI for both the C# and the Bb notes, you will need to add an extra lower rod to the A pedal.

There will be a timing problem with the sixth string compensator, however, if you attach the compensator rod to the knee lever that raises the fourth and eighth a half-tone, the steps will be less noticable. Of course, the knee lever may not be suitable for your requirements, but usually sixth string cabinet drop is most pronounced when using pedal A and raising E's at the same time.
