I'm playing a BC Rich Warlock with a Widow headstock with a Floyd Rose II and 2 humbuckers. It's a violent looking piece of guitar. I don't like 7-strings, they seem kinda trendy to me... Most players I've heard who play 7-strings don't even use the higher end of the guitar, so I don't understand why they don't just tune down 2 1/2 steps and go with that, instead of working around the akward situation of having a fatter neck. It'd drive me fawking nuts... Although Steve Vai, and, I think, John Petrucci put good use to 7-strings.
