Topic: tuning pulls driving me insane |

When I engage my 5th pedal (normal 6th pedal) by itself, it comes up a sharp F. When I have the lever that flats the E's engaged, and press 5, it's a flat E. The Eb lever is tuned correctly. This making me crazy - suggestions? I'm sure I'm doing something wrong, here...
Just in case it matters, I have a 12 string Uni, 6 pedals and 5 knees, the pedals are A,B,C,5,6,7

Christopher, it sounds like your roller nut is dry and sticking, not letting the string return all the way after a raise, or lower.
Loosen the string, move it off of the roller and put a small drop of TriFlow (or high quality oil, if that's what you prefer) on the junction of the roller and it's shaft.
All those rollers must move freely. Any friction will cause the problem you describe. If you see that one of them is sticky, you might want to remove them all and thoroughly clean them. Be sure to keep them in the original order.
If cleaning the nut rollers doesn't solve the problem, then you might need to lube the changer. Again, a small drop of oil between the changer fingers should do it. But, you might end up needing to remove the changer for a good cleaning...which may be best to have done by a pro.

Thanks for the tip, Mike. The instrument just got serviced (more pedals, new setup), but I'll go ahead and put some oil on the roller, and see if that helps. I just saw Lynn Stafford, who did the work, and he also suggested that I tune the pedal with the E lever engaged, which I'll try, as well.
Playing over "Giant Steps" at 300 on a jazz guitar seems easy, in comparison...

I think that you've been chasing your tail trying to tune the split.
Back off all the nylon tuners.
Tune the open string (at the machine head)
Press the raise pedal and tune the raise note to F using the nylon tuner attached to the rod from the pedal bellcrank
Press the raise pedal and at the same time activate the knee lever that lowers the note, and tune the split note to E using the nylon tuner attached to the rod going from the knee lever bellcrank to the lower segment of the changer finger
Release all pedals and levers, then activate the knee lever that lowers the note. Tune the lower note to Eb by either using the setscrew on the changer body (if it has one), or by using the nylon tuner attached from the knee lever bellcrank to the raise segment of the changer finger |

| You might need to simply tune everything in the correct order. Check Newman's tuning chart, that says to first tune the open strings, then the ABC pedals, then all the knee levers. Last, hold the 4 and 8 string lower lever while tuning the 4, 5, 6, and 7 pedals. |

I always tune my B6th pedals with the Es lowered.
Because that's how I use them.

Good point - I'll tune them that way and see.
I find I'm mostly not thinking of it as two tunings, but as one complicated one, so I'm using all six pedals, E's lowered or not, depending on what I need at the time.
Still, it makes sense to tune the right side with the lever engaged, since that's where I'm having trouble.
Thanks for all the good advice, everybody!
