Just what I needed

By Michael Shaw from Philadelphia USA

These are great. I was making due with an assortment of various maker supplied smaller wrenches. One thing I would recommend is printing the wrench size on the handle.

6114 wrench

If you own a newer Martin, this is a must have. Since the truss rod nut is at the neck joint you need the 4 and half inch reach, and having the leverage from the handle is very nice. A regular Allen wrench is a pain since there is only about an inch of it that you have to apply pressure. No more running to a music store if you need to tweak the neck!

Sound hole truss rod wrench

The wrench I needed wasn't a complicated item, but it was an item I could not live without here in Wisconsin. It has been a harsh winter, causing heaters to run more than normal, causing problems with guitar necks. I have a Martin d45 that is my pride and joy. The neck has not warped in almost 17 years, it warped slightly, but enough that I had to correct it, so I looked in my StewMac catalog and found this wrench. it is easy to find anything you could ever want for guitars in there, it has become like a guitar survival book for me. The wrench was the perfect length, it fit easily through the hole, so there was no danger on scuffing the finish, that was very important to me! To order off the website, was the easiest, most user friendly site I have ever used. They gave me an estimated time of arrival at the confirmation of my purchase, and also offered tracking info on my order, and to my surprise the order was I think three days earlier than estimated. That was an important thing in these cold winter days, when you develop cabin fever. I also enjoy the repair tips they email me, I have learned valuable information that keeps my guitars in the optimal playing condition, improving my playing, and my enjoyment. THANK YOU STEWMAC

5-3/4" reach is too much

By Love my Snark from dallas, TX
(Customer's Reviews) Tuesday, December 24, 2013


I had good luck with the 4-1/2ö soundhole wrench. However, I was a little suspicious that the 5-3/4ö would be too big, and I was right. The reach is too long to fit through the soundhole AND fit into the truss rod of my Ibanez OOO guitar. (#6212, 4mm, triple bend, wrench).

The right tool

By Fisher from Utah
(Customer's Reviews) Thursday, October 17, 2013


Going at your $4k fine instrument with something not quite right kept me up at night. Alternatively, I just didn't make the adjustment and hated playing my 000-042. Not any more. The right tool makes all the difference. This is it for Martins.

Just what I needed.

When I needed a truss rod tool for my 90s Martin 000C16-RGTE, Stew-Mac recommended exactly the right model. Works great!

Martin Truss Rod Wrench is a Winner!

By Mack L. from California
(Customer's Reviews) Tuesday, May 28, 2013


When you need to adjust the truss rod on a newer Martin, this is the perfect size! Not a bad price either, when they make 4mm with a 4 1/2" reach i'll buy it in a heartbeat.
