ok, thanks.
Does the 12,75" + 1/16 must be calculated for the bass side of the bridge or the treble side. Also, do I measure from inside the 12th fret or outside?
I will install a tonepros tunomatic bridge and tail piece on my project guitar. I want to know how to determine the exact location for the hole in the body. It will be a 25.5 scale length guitar.
