Yes the neck is little larger and you have to hold down double strings. It has a regular set and an additional "light" set of strings. the lighter set of strings has pitch an octave higher for 4 of the bass side strings and doubles the other 2, I hope that makes sense to you. So the coolness of the 12 string sound comes from additional octaves and overtones generated... Usually songs with big open chords sound great while other songs may or may not sound good on a twelve string, you just have to play with it and see if it fits the song... It takes a little getting used to when chording because of the additional strings, but with a little practice most people adapt pretty quickly... I hope that answers your question... if you play guitar you should try a twelve string out for fun... if you don't play you might have an interest in starting to learn, there are a lot of free resources on the internet and it's really hours of fun ;9)
