Barrel String Retainer Guide

Individual barrel string guide for use on Stratocaster/Telecaster guitars.

String trees are a necessary addition to most guitars that don't have an angled headstock. They provide the correct amount of tension where the strings break over the nut.

Essentially, they increase the string’s break angle (the angle a string makes where it bends over a nut or a bridge) and ensures that the strings won’t come unseated in the nut slot.

The added pressure also means you'll get more sustain when the string is played open.

Overall, string trees are a vital component for guitar with a straight headstock design. It is a very simple component but can significantly help tuning stability.
