Soundhole Truss Rod Wrenches

Arrived fast and in good condition. Works great and is comfortable to use.

Needed to tweak the truss rod on my Martin 00-18V, but no standard allen wrench was going to handle the task without serious compromise and risk of damage. A quick Google search and I found the perfect solution at Stewmac.com! This wrench is custom-fit and purposed for this job, and allowed me to make the adjustment and quickly eliminate the buzzing that had crept into my setup.

I know I can count on STEWMAC in the future for any specialty tool needs that should arise. Thanks!

Got the #6110 for a 2000 Martin. Perfect fit. Very high quality tool; an excellent value. Don't hesitate to get one.

The 6114 works perfect on my Martin 000-28EC. Great tool.

Got the wrench to access that hard to reach truss rod socket. The ball end was a must and it worked great. Another well made tool offered by SM.

I had a 2" version of this truss rod wrench that would not work for a recent guitar. The 4.5" one works on a wide range of guitars.

For truss rod adjustment, this is a must have for all Martin owners! I used an auto tool before I bought this and must say it is the correct one. I don't have to loosen my strings to get the Allen key into the sound hole. It's great for fine tuning/truss rod adjustments. No other tool works.

StewMac is THE go-to place for good quality, hard-to-find tools.

Well made, does what it should. The ball end is very helpful.

You'll need it to adjust acoustic necks with out removing strings. I bought the 4.5" one and it fits all the acoustics I come in contact with. The 2" one won't do all the jobs you might need.
