Clean look. Better string control. Easy headstock upgrade.

Upgrade your guitar’s tuning stability and headstock performance with this Brio Pro Steel Barrel Style String Tree Set.

Why Choose These?

Traditional string trees do the job, but barrel-style guides offer a clean, compact, professional look while helping the strings sit with better control across the nut. They are especially useful on headstocks where the B/E or D/G strings need more downward pressure to prevent buzzing, sitar-like ringing, or tuning instability.

These are a simple upgrade that can make a noticeable difference in feel, stability, and overall headstock presentation.

Installation Note

Before installing, confirm placement and string path on your specific headstock. A small pilot hole is recommended to help prevent finish chipping or screw breakage during installation.
