2026 Martin 000-18 truss rod issue
So pulled my guitar out of the case to do some strumming. And felt like it was lightly outta tune even after using my regular tuner. I tilt the guitar around to inspect it and here this “knocking” sound every time I tilt upside down and back. Nothing inside the body. Do it a few more times. The knocking sounds and feels like it’s coming from the neck. I take a look inside and it looks like the truss rod nut came off where the neck meets the body. Anyone have this happen before? I’ve been keeping the guitar in the case with humidity packs. The rest of the guitar seems fine but now I’m freaking out. I registered the guitar with Martin as soon as I purchased it earlier this year. Unfortunately, I’m in Guam for work for the next six months so I’m not sure I’ll be able to get it to a good luthier any time soon. Any advice or input is welcomed and appreciated!
