Nut spinning off end of truss rod
I have an S1520 with the original Wizzard neck. One of my favorite guitars, chipped here and there but just a solid-playing guitar. I've had it set up perfectly for me for some time but decided to make a few adjustments. I installed an Edge Pro some time back and there's not a lot of room to pull up. I also have a brass big block.
So I decided to try a Crunch Lab/Liquifire pickup set I've had lying around for about a year. While I was at it, I filed out some space to enable a bit more pull up on the trem. Set the guitar up in identical fashion to the way it was before. Everything seemed fine.
Let it sit for a week and after picking it up, noticed I had a low E buzz. So I take a look at everything and raise the bridge a hair. Still buzzes. Check neck relief. Pretty flat. I'd been opening/closing the windows and cycling the a/c lately due to weather. Gets hot during the day and cool at night and it tends to wreak havoc on my setup.
I go to adjust the truss rod and turning it counter clockwise has the nut coming off the end of the rod. For some reason I thought this was a dual action rod. It does not have an allen wrench slot. Uses a socket to adjust.
Is it a case that I've somehow run out of adjustment range or is it a matter that the nut is supposed to be "locked" on the shaft? Loctite?
I've not encountered this situation before so any advice appreciated.
