Truss Rod Adjustment

If its a Allen key you just need to find the right size.

Do yourself a favor and go but a full set if metric and standard. They will always come in handy.

 

Tambo, in that case, a photo would help. You could ask the maker also.

 

Which end did you look at? The end on the headstock or somewhere else?

 

You're welcome. I'm sure it's just a hex head an Allen wrench can fit into to.

 

Does it look like this? http://www.stewmac.com/shop/Truss_rods/Adjustable_truss_rods/Traditional_Truss_Rod.html

This one, a Gibson style rod, uses a 5/16" hex head.

 

Tab, that is not a hex head. It may very well be an Allen head that was stripped out. Hopefully not. Did you try different size Allen keys? It may be that the Allen key fitting is deep down inside the nut. Try some metric and SAE sizes and let is know what happens.

Dang that sucks. Well at least you figured it out. Gives you good reason to get a brass nut now! Haha

 

My next suggestion after you found the allen key that fit was too spray some lubricant down into the hole to loosen up the truss rod before you tried to turn it. But I guess that's all water under the bridge now.

If its a single acting truss rod, you may be able to unscrew the nut and remove it. If it's a double acting truss rod and you are able to loosen the nut, it will add relief to the neck. Also, if its a double acting truss rod, the only way to fix the neck is to remove the fretboard. Is the relief out of spec on the neck and is that why you were trying to adjust it? If it's playable and the relief is OK, then I would leave it alone.

 

Great! If you got it to work, then leave well enough alone. If you ever decide you want to fix it, and its a single acting rod, the nut will thread off the rod. Then after removing it from the headstock hole, you could try to find a replacement.
