This is an essential tool for adjusting Larrivee truss rod nuts.
This modern T3 style Larrivee truss rod wrench will fit Larrivee guitars with serial numbers 132000+.
Please note: Older Larrivee guitars with serial numbers between 4001 and 34999 require a T1 type 3/16" wrench (4.78mm) and guitars with serial numbers 35000-131999 require a T2 type /32nds wrench (3.97mm, or a whisker under 4mm) - both of which I also sell.
