Topic: E raise coming back sharp on Sho~Bud |

I have a '75 Sho~Bud 6139 S10.
When I raise the high E (either with my knee lever or my C pedal) it comes back slightly sharp and I have to touch the E lower lever to bring it back.
I have a Day setup to my raise is on LKR and my lower on LKL.
When I raise the E, as I bring it back down again, I can see the nylon tuning nut for the E lower move out slightly, also the LKL lever itself moves very slightly to the right as the E is released.
If it's an easy fix, I'd love to sort it out but if not, I guess I can live with it and am starting to get used to making that slight movement left with my knee after an E raise.
When I use LKL, it comes back to pitch - no problem.
Has anyone else had this or can suggest a solution.
Thanks. |

If it has a helper spring (arrowed green ) on the 4th string, remove it.

Your pull fingers are probably draging on each other gummed up...gotta lube them and work em free loosen the strings and pull on the fingers .
Or take em off and clean em |

Thanks for your replies guys.
Turns out it wasn't the helper spring but some lube in the changer fingers fixed it and it's working perfectly now.
The bad news is that I guess that wasn't the reason I didn't sound like Buddy Emmons  |

To add to what Phillip has said...
With any changer, if it has an issue of returning to pitch.
FIRST release all pulls to zero. remove the string, with your finger, move the changer finger assy and "FEEL" if it has any resistance.
This is step one especially for an older Steel like a Sho Bud from the 70's !
If there is NO resistance, retention the pulls, one at a time to identify whats causing the issue.
My take, if there is any resistance whatsoever, pull the changer, clean and burnish each changer finger and reassemble with light oil. Adding lube to only one finger is like changing one spark plug on a V8. Then, before you re-string and connect the pull rods again, check once again for absolute free movement of each finger.
Also don't forget to tap the rivets ever so slightly on the reverse side ,on each finger ,to be sure the finger arms move freely.
Our Steels all look pretty darn nice from the top, but even a clean car with a blown motor looks good ! 
Here's some before and after from a mid 70s Sho Bud changer that was exhibiting some "resistance". Too much lube, probably several types of lube added thru the years.
