String gauge change - tune issue

[Terry Srader]

Just changed to LiveStrings and different gauges.

Tuned all open strings no problem. When tuning string 6 (pedal A) to A, the open string goes higher as well.

Can soeone provide a "how to" when changing string gauges on what mechcanical change is needed to bring all strings into correct tuning.

Much thanks.

That's a condition called "overtuning."
Did you go from a plain string to a wound one?
If so, you'll have to adjust the pedal to have more travel or move the pull rod farther out on the bellcrank, as wound strings need more finger movement to get the same amount of pitch change.

Have you ever noticed those little white things on the right end of your guitar? Try cranking on them.

Yes, i've done that but that is what's making the open note to go sharp.

As to a guide for what happens when you change gauges, the following might help:
1: the core of a string (if wound. If plain, it's ALL core) is what matters.
2: if you make it smaller, you'll need to move the finger farther. If you go from plain to wound, you'll need to move it a BUNCH farther.
3: if you make it larger, the finger will need less travel.

2 and 3 can either be accomplished by re-rodding a change to use other holes in bellcranks and fingers or by adjusting pedal/lever stops.
Re-rodding makes more sense, because most changes work more than one string.
