That's called a string tree. It puts tension on the strings above the nut. When the headstock doesn't have a break angle you need them on the lighter strings. Gibsons use an angled head, fender does the trees.



Your cigarette goes between the 1st and 2nd strings up above the tree. Or tucked under the 6th like Clapton used to do. The strings are numbered upside down as you hold it 6: thickest, Low E 5: A 4: D 3: G 2: B 1: high E
