Groovetech Cruz Tools SOUND HOLE TRUSS ROD WRENCHES GTAW4 (4MM - FITS MOST BRANDS)

Essential Information About the Groovetech Cruz Tools Sound Hole Folk 4 mm Truss Rod Wrench
• Access through the sound hole : designed to reach the adjustment nut from inside the body, where many acoustic guitars make the task difficult.
• 4 mm size : ideal for many "folk" acoustic truss rods requiring a metric wrench.
• Safer adjustments : allows for more precise neck relief adjustments than an unsuitable tool.
• Workshop tool : a must-have for regular maintenance (action, playing comfort, prevention of buzzing).
