Waste of money? Or are they any good? What genre would they mainly be played in? Any difference between a regular 6-string guitar (besides the number of strings)?
thinker sound. you can use it where ever you please man. there arent specific instruments for genres, y'know? and its a waste of money only if you wont really use it
I personally love my 12-string, it's good for when you need to fill in some gaps and a regular 6-string won't do it for you. get a cheaper one though because they don't tend to last long with such high tension on the neck. just make sure you play one first too, it's almost like a completely different instrument. I felt like an ass when I first tried to play one and I could barely play the correct string courses without hitting others.
