i have a bunch of old usa made peavey guitars that only take thin walled female truss rod wrench that works on my gibbons too! i looked forever for a peavey wrench! people have to grind down sockets and use an alien key to turn it! this saved my sanity and time and redneck butchery! i can't say enough, if you have a usa peavey, you're in business !

I wasted a lot of time and money trying to get the correct tool to adjust the truss rod on my Peavey tracer. I tried alternatives because I felt that the shipping cost from Stewmac was high. And it is, but I got the tool I needed to get the job done.

This "pocket" truss rod was too long for the pocket of the guitar I bought it for. I had to grind off the point on the back and cut an eighth of an inch off the front to get it in there. I would have been better off just welding a rod (handle) onto on old 9/32" socket.

I ordered this Gibson Truss Rod Wrench and as soon as I removed it from the package I was impressed with the weight, the finish, and the way it removed the truss rod nut that I have been trying to remove using the wrong tool.
I am so glad I made a wise investment buying the right tool for the job.
Thanks, Stew-Mac!

The length of the wrench part not the handle is long and can't fit down in to get to the nut in some applications.

The 5/16th is the perfect tool for udjusting the older Peavey guiltars and basses. Its longer and tapered design fits where the other tools wouldn't reach. Thanks again.

Does the job in most cases. Probably a little longer than i expected but i as said does the job

for 2015 Gibson ES335: 5/16" socket was correct, but too long. would not fit into the carved cavity to seat properly. was able to locate a Gibson tool (had the Philips head handle). fit perfectly.
the Stewart tool was 1/4" too long to seat properly.

I needed to make a truss rod adjustment form my vintage 1979 Peavey T-40 bass. The wrench fit perfectly and I was able to make the correct adjustment.
