Good god - does this argument still exist?
It is based on a super-philosophy - that there is 'one guitar to rule them all'.
Where does that end? You could say the same about guitar players.
The eventual result would be only one guitarist in the world playing the only model of guitar available in the world.
Articles would be written about his prowess by the one music journalist in the world.
Surely the beauty is the variety - the variety in players as much as in the instruments themelves?
In some people's eyes, Paul Simon isn't the best guitarist in the world. But i'll tell you something - he's the best Paul Simon i've ever heard
B.B King is no Joe Satriani, but he's one hell of a B.B King
Joe Satriani is no B.B King, but he's one hell of a Joe Satriani
There are many, many great guitars out there.
A few I own that I would recommend (that haven't been mentioned here) are:
Vigier Excalibur
Parker Fly
Caparison TAT
Zodiacworks Darkstar SC (still waiting on it, though)
Buscarino Virtuoso
Gretsch
etc etc
Robert Johnson also managed fine on many old, beat-up guitars.
