Please note that Schaller tells you to use a 3 mm allen wrench, which is WRONG. The only allen wrench that fits is imperial 1/8'' (3,175 mm, same as truss rod on American Fenders) otherwise you will strip this screw as soon as you apply any force to it and... have fun drilling that out of your guitar.
Otherwise well fuctioning. Extreme drawback that they switched from regular screws to Allen keys for this though.
