Hopefully someone here can lead me in the right direction. On my 1973 Pro II, after pressing the A B or C pedals, it will cause the E's to be slightly sharp until bumping the E lever (LNR) just a bit. I would understand if something were not returning all the way but A or B shouldn't affect the E's even slightly should it ? I am using a Peterson Strobo to tune with. The E's will be just slightly sharp. It seems to be pulling the LNR to much back to the left when releasing the pedals as I can rest my leg against it and it works fine. Am I asking to much of this guitar or do I have an actual issue ? What does seem to work is if I tune my open E with the AB pedals down. Does all this make any sense ?

When did you last clean the changer? And maybe check the lower return springs to make sure they haven't got weak and are pulling away from the stop...just a couple thoughts  |

Thank you Storm,
I haven't cleaned it as of yet. Just acquired the guitar a few days ago. if the springs were week, wouldn't that cause it not to return enough ? When using LNR the return is fine. It only gets sharp when when Pedals are used. Even A or B will cause it. It's like they are bumping the knee lever to far to the left when using them.

It seems to work fine if I tune My open E's with pedals AB down. Is that the correct way ? Don't have to do my stage one like that so all this is rather new to me.

Try flipping it upside down and looking for something rubbing or catching when you move the pedals.

This is what I have seen several times on Buds... Some have an adjustable lower return, and it might need a turn or two.. either that or replace the spring.... bob

If you have a 2 raise/1 lower or 1 raise/1 lower changer, those fingers have slots that glide over the spring plate. That's a common place for friction to keep the fingers from returning to their resting position. I've remedied that problem by tightening the return springs on strings that return flat. You can do that by cutting off several rings off the spring and then bending a new hook using needle nose pliers.
That's only one possible reason. I also had fingers that were worn down, a brass swivel on the bell crank being worn down to egg shape and causing erratic tuning and even pull rods rubbing on a pedal cross-shaft.
Bottom line, you must look at the mechanics in action to find the source of the problem. I like to set mine up on a table and working the pedals with my hands while carefully looking at the entire mechanical train until I can see what causes the problem
