Yes, I agree.
This will probably require shimming of the nut.
This will probably require a small adjustment to bridge height.
This will definitely require spring tension adjustment.
And, finally this will require re-intonation.
Thanks for the heads up on overall string tension limitations.
I mean, I am not putting on 12-54.
In fact, my total string tension now is 85.2 and I am increasing it to 103.6.
Thanks
