Mastery MST String Tree

The Mastery MST String Tree offers a refined solution for improving string angle and tuning stability on guitars that require additional downward pressure behind the nut. Unlike traditional bent-metal designs, the MST is fully machined from solid material and finished with Mastery's proprietary hard chrome plating. This ultra-smooth surface minimizes friction and eliminates the need for moving components, ensuring consistent performance under dynamic playing conditions.

Engineered with a slightly increased break angle and a single string contact point, the MST preserves tone and sustain while reducing drag during bends or tremolo use. It includes a custom stainless steel spacer and an extended stainless steel screw for secure installation and optimal alignment. Designed for precision and durability, the MST is an ideal upgrade for players seeking improved functionality without compromising aesthetics.
