Hi all, here is a little support question... Recently my A25 developed a rattle, which I isolated to open G string only. After removing strings, checking for loose ball ends, removing strap button plug, poking around inside the guitar, tightening the truss, I discovered that when I push my thumb hard into the back of the tuning machine of said G string the rattle stops. I loosened the string and tightened the screw at the end of the little handle. Also checked the nut around the thingie which you attach the string to (is this the tuining peg, or what is it called, my english seems to fail here).I dont have the right tool so I used pliers but the nut seemed pretty tight.
So what is the next step? Is the tuner messed up and needs replacement, or should I get the proper tool for the nut and disassemble the whole thing? How should I go about this?
