I'm looking to install string trees on the necks of two of my builds. Both have J-replacement necks: one is a Moses Graphite and the other is Warmoth. My question is if there are any standard measurements to use for determining where between the D and G strings to place a round/fender-style retainer. For example, should the hole be drilled .5, 1, 1.5 or 2 inches from the nut? Should I measure for placement with the strings on the bass or is there some set formula to use? Thanks in advance for any help.
