Premium Truss Rod Wrench – 1/4". Having the right tool to perform your key gear adjustments is critical. From tip to tip, Music Nomad’s premium Truss Rod Wrench is packed with unmatched features and benefits. The carbon steel construction gives you the quality you need every time, while the ergonomic handle design provides comfort and ease when using. The protective rubber bumper keeps you from jamming the metal handle into the side of the truss rod opening. We even designed a magnetized screwdriver for the small screws found on the truss rod cover. That’s Music Nomad quality – raising the bar in equipment care.
