| I know i have seen this discussed before but i can never find anything with the search for some reason. anyway 6th string plain .20 gage when I it to f# it returns flat,I barely touch the b pedal and it comes back to the correct pitch .I have felt the changer finger and it is coming all the way back to the stop. any ideas ? It is the only change on that knee lever.I also oiled the changer and the the rollers at the keyhead end. |

1) are you SURE the nut rollers are free-spinning?
2) what kind of guitar is it?
If you have any unused cross-shafts or a cross strap like Zums have, you might want to put a Zum/Franklin style "drop return compensator" (really more of a regulator than a compensator).
If it's not the roller, it might be the scissor lightly "bouncing" off the stop bar (this is what I think the drop return regulator stops).
If you have adjustable return springs, try giving it a turn or two.

| Its a Rittenberry, the rollers are free and i tighten the return spring a couple of turns didn't make any difference everything seems to be working as it should be. when I lower it it goes to the correct pitch but it comes back consistenly about 8-10 cents flat touch the b pedal and it goes right to where it should be.If I back both nylon tuners off for the pedal and the knee lever would it make any difference which I tuned back up 1st? |

I'd tune the pedal first, the split second, and the lever last.
Before you blip the B pedal, is the lowering scissor sitting off the stop bar, or is the raise scissor sitting slightly wonky?

Also, is there slack in the knee lever? If there's no slack, things ging oft agley.

If you feel a little adventurous, you can try adjusting the return-spring to "just enough tension". It usually is tensioned more than necessary to begin with, and if you have tensioned that spring a couple of turns further during setup for this change, then it really is tensioned more than necessary.
The lower-return spring ballances the changer best if it is tensioned just hard enough and no more to keep the lower-scissor stable and reliable against the stop-plate during raises, and then a half to one turn higher tension to weigh up for natural spring-weakening over time. Thus, testing and adjusting that spring while pushing the B-pedal for raise to "A", is how it is done.
Testing and adjusting the lower-return spring while lowering makes no sense - too high tension on that spring makes lowering unstable by pulling on the raise-scissor, and too low spring-tension makes raise unstable by pulling on the lower-scissor.
Good thing is that you can always adjust the lower-return spring back to where it was, if "fine-tuning" its tension doesn't help on bringing the return to neutral from lower in pitch. |

before you go crazy, before you do anything else, release the pull on the 6th string B Pedal, back the tuning nut all the way out. Tune the natural note. Now check your 6th string drop and return.
What did you learn ?
When was the last time everything worked fine ?
Did you do anything since then ?
First things first.
Next time don't OIL the parts first.

Hi Lee, one other thing to check is the cross rod.
Make sure that it moves very easy. If there's the
least bit of binding it won't return back to open.
