I'm still learning to play my guitar - and probably always will be learning. I do not have a musical background either.

My question is . . . what is the "set 8" at the end of many of the songs listed in the chords/tabs section. Does anyone know the meaning and history of this notation?
It means those songs were written on 8 string guitars. Bob Dylan and the Bee Gees are well known for that kind of stuff.
