WRMG Truss Rod tool

[John Matrix]

Does anyone know what size wrench I will need for my WRMG? Its hard to get a measurement while it's inside the headstock.

3/16-inch hex wrench:

hmm, I'm not sure that is correct. This is what I am looking at:



Seems like it needs on of this style wrench, just don't know what size. As best as I can tell it's a 1/4 inch but they also sell a 5/16 one and that is too close for me to tell with just a ruler.

Imports are metric.. 7mm pipe wrench is correct one. Some late ones from Japanese factory have 4mm hex wrench.
