Truss Rod Wrench for Gibson Acoustics

[Nick84]

Can someone tell me what size truss rod wrench I need for my J15 and J35? Are they the same size as the electrics etc?

5/16", if it's the same as my AJ.

Thanks guys

Good info since I also need a truss wrench for my J-45. Question: is there any advantage using a straight over the more common right angle wrench?

I have great results with the straight wrench - I think it give a better straight torque and helps avoid slipping and stripping the nut as might more easily occur with the right angle. the straight approach also gives you access to the whole radius of the turn. Not that one should turn it much anyway, but I find it handy.

I use a nut driver with a long extension and socket.

Thanks. I can mentally picture how the angled wrench would be more prone to stripping the nut since the wrench would have a force directed parallel to the truss rod in addition to the torque.

Straight will have better advantage over rt angle. You won't need much of a turn .
Maybe an 1\8 to a1\4 turn and with a straight you will have better direct control .
Rt angle and you may easily put more power or torque into your adjustment then you need..
Also the more or bigger the tool the easier it is to drop part of the wrench and mar your guitar.
Having said that, make sure your socket is tight on driver.
I once had a loose socket fall of the driver when pulling it off the adjustment but, a nice character mark on the guitar
as a reminder.

Should be 5\16"

I suggest not paying the Stewmac markup. The one they sell you can buy at any hardware store for about $6. If you want one with the curved design
