this is really what drove me to ask the question.
it seems that lots of times guitarists are competitive to the point of being detrimental to the overall, or they're the guy who isn't really adding much (maybe he owns the pa?). but lots of times even the most attention desperate guitarist will be more attuned to the rest of the band when there's no direct competition.
either that or i just have a bad attitude about guitarists.
I think the modern role of guitar in Rock/punk/metal is quite literally now to just be a **** cannon because its frankly so good at making obscure noises. The less talented musician has usually the easier time.
