7 strings will only be popular until the 8 string models come out this Spring, this whole craze is being secretly manipulated behind the scenes by a powerful cabal of guitar and string manufacturers, within 5 years we will only be able to buy 13 string guitars, the guitar will become a 2 player instrument, I think the record companies are in on this too, with each guitar having 2 players, who will want to hear the sound of "one hand tapping".
