Truss Rod Question: Epiphone Acoustic Bass

[devnulljp]

Just bought a used Epiphone El Capitan acoustic bass.

1. I need to adjust the truss rod, but when I took off the cover there's no hex nut in there, just a screw-thredded hole. Do i need some kind of head/adapter or special tool to adjust the truss rod? Is something missing?

Can you take a picture? Most epiphone guitars have a socket at the Headstock that requires an Allen wrench. If the El capitan is a Gibson style rod, it would require a thin wall 5/16" (I think) socket. If it's Gibson style, it is possible for the nut to be unscrewed all the way, which would leave just a threaded rod sticking out.

It looks like this. Any ideas? Something missing?

I'm no expert on epiphone truss rods, but it looks like it extends out about the right length, so it likely nothing has broken off. I would expect to see flats on the inside of the hole to accept an Allen wrench, but it looks like it is rounded out maybe? In the first picture in about the 7-8 o'clock area of the nut, it looks like there may be a flat side left? Have you tried an Allen wrench?

If it is rounded out, you could try something like this: Invalid Link Removed

Figured it out -- turns out there *is* a hexnut down in there, but I needed a smaller Allen key to access it is all.
