Genuine Dynaguide String Tree/String Guide, Off-White Manufacturers Part Number: DY-GUIDE-WHITE The Dynaguide string tree is simply the best option in existence for replacing or upgrading Fender-style string trees. It was invented in (and is made in) the Netherlands. The Dynaguide is unique in that it doesn't clamp or bind the strings, it moves with the strings - so instead of friction being your enemy it's your friend! It uses that friction to let the square ring swivel in the base, near to the headstock. It's especially effective on instruments with Tremolos.Features: No detuning problems Non-destructive application (important for vintage guitars) Self-aligning string angle Contents: Guide Bar Screw Available in both black and off-white.Installation Video Buy with confidence and full warranty from SportHiTech.
