Perfect fit for Martin LX1
The 5mm Wrench is a perfect fit for my Martin LX1. Its long enough to reach the deeply inset hex and the ball end on the longer side makes it easier to actually get it to engage (my biggest issue!). The length is great and it was very easy to adjust my truss rod using this. I don't actually have any use for the 4mm, but its nice to have.
