The nut of a guitar is non-adjustable. The only thing you can do is file it, or remove it and shim it.
The purpose of the nut on a guitar is to support the strings, maintain their spacing, and help transmit vibrations to the neck and body of the guitar.
It is possible to fit the guitar strap to it if it has a strap peg. The strap may or may not be too long, however. If your guitar or ukelale does not have a top strap peg, like me, then you can tie a long string or strap behind the strings, above the nut. I reccomend using a wider strap to prevent it from cutting into your shoulder.
Try to fix the nut. the strings could have moved it a little. i had the same problem when i restrung my guitar.
Yes, by attaching a converter nut to the existing nut on your guitars' neck. A hawaiian steel guitar nut converter will raise the strings considerably so you can use a slide freely. These are usually made of cast metal, and is placed over your the nut on the guitar. Expect to spend $5 to $10.
No it does not have the same lug nut spacing as the cobalt.
Yes, the barrell, shroud and nut assembly are the same.
The guitar nut is the rectangular piece that the strings lay on as they come off the peghead and onto the fret board. Most of the time the nut is a whitish color bone, Tusq, or plastic, but can be metal (locking nut)
The 'scale' of a guitar refers to the average string length between the bridge and the nut of the guitar (this is the average length because intonation at the bridge means that not all the strings are identical in length from nut to bridge).
there's two mounting studs you can adjust with the same allen key you lock the strings in and lock the nut. One on each side and it can be done on a perfectly tuned guitar.
The lug nut pattern is the same - 100mm x 4.
You can't!
