I'm going to start this off, this "tip of the day" post with the hope that others here will pick-up and contribute your tips too. If you have a good idea or industry best practice and it's vetted to be a good idea and not harmful to a human or even worse a guitar...
please post your tips of the day too in this thread. Thanks!Fender G string break angles. Leo Fender was a genius in many ways and went a very long way to bring very decent if not iconic instruments to working folks who could afford his wares and then we know what happened next, some of the greatest music ever was made.
Leo had a few issues though with some of the physics and a very well known issue and fix in the professional Lutherie world is how to improve on Leo's lack of break angle for the G string on his bolt-on necks.
If you look at a Tele or Strat with only one string tree and view the G string breaking over the nut you will see what I mean. A heavy handed player can easily hit the G string hard enough that the vibrating wave may, may breach the G string nut slot and sound like....... (insert your word of choice here I know what mine would be...).
So the fix is easy and I do this every day these days since I am always on a Fender at least once a day now. Hold out and wind at least 6" of additional G sting slack onto the tuner post. Wind it right down the the edge of the post nearest the peg head. View it again sideways and you may have doubled the poor break angle. You can do this with the D too although the D is not as problematic but does benefit with a heavy handed hitter.
More recently with the advent of newer tuners you will see that some models have a shortened tuning post on the D and G and B and high E for this exact same reason. Multiple string trees are also one approach to improving the shallow break angles.
So this is a tip that you can do right now, no changes need to be made to the guitar, no tools to purchase and a bit of a historical discussion here with an equally time tested historic fix. You can also show it to your customers so they can do it too come restring time. They will appreciate that you shared this with them.
Was going to take a pic of this to post too but the two Strats I have have here at home with my Fender that already has two string trees and my Suhr that has locking, short post tuners both fixes intended to improve the shallow break angle on Fender style bolt-on necks. As you can see it was enough of an issue that the industry even developed products to counter it.
So if you have any tips to share please do? Thanks!
It seems to be exactly that, good one JF!
