Soundhole Truss Rod Wrench for Martin Guitar

The Soundhole Truss Rod Wrench with a 4-1/2 5mm, is a must have for any Martin guitar truss rod adjustment. I spent years struggling with a regular hex key and this new truss rod wrench from Stewart-MacDonald makes adjusting your Martin truss rod a breeze. It is a must have for any guitar.

Need one more size

Great wrenches. I use them every day. But, I need one more similar #6110 with size 4mm and 1-1/2 reach. Have plan to buy #6099, but it'll be good idea to change handle color. Thanks to StewMac and Best Regards.

Correction

the 1/8 inch is about 1/64 undersize, not 3/64. Brain lock.

Not really 1/8"

The 1/8" wrench sent to me is about 3/64" under 1/8", closer to 3 mm.

How about a 4mm version ?

These are great wrenches but more and more instruments are using a 4mm hex socket these days. Both the short and long reach would be a great addition to the set.

Works as Advertised

Easy and comfortable to use. The ball end helps a lot. Sturdy and looks like it will last a lifetime.
Price is right.

Can't ask for more from a Truss Rod Wrench.
