6 string vs. 7 string
First off I want to say that I think 7 strings are way better than 6 strings for sound of KoRn and other nu metal bands because of the extra string it gives a heavier better sounding tone in my opinion. I personally don't own a 7 string but I am yet to copy the sound of KoRn and other 7 string bands with a 6 string. In my opinion 7 strings are 100% better in every way because of the sound, looks, and feel, except for beginners, because of the extra string the neck is thicker and harder for beginners to play. For experienced guitar players it is pretty much hassle free, in my opinion. Anything else to add, go ahead!
