I’m replacing a neck on a bass that use to have a 32 scale to a 34 scale. The bridge needs to be shifted lower to have proper scale. I know the obvious part that I need to have 34” between nut and bridge saddle.

But my question is should I do the measurements with the saddles in a neutral, mid travel position? Is there a particular string I should set it to? And any good shady mechanic tips?

Thanks in advance.
