I don't think you can say any of the previously listed guitarists suck, aside from personal opinion. IMO they are all very good at what they do, but I wouldn't have called them all virtuosos. Virtuoso by definition may mean very skillful in the technical aspects of an art (music), but to be a masterful musician you should understand and be just as skillful in all the aspects of music. And to me having such a high level of technical skill doesn't limit itself to just being able to play ridiculously fast or playing the most complex and difficult song competently. I mean just because one song is harder to play than another, that doesn't mean the harder song is a better song. A good song to me is one that captures the listener and takes the listener into the mental state of the musician that wrote it. From the first note to the last, the song is a journey and by writting good character to every section of the music; the musician is able to make the listener feel every step of the journey. I think when you listen or reach a level to where you can effect the listener in such a profound way, then you are a virtuoso. Very few (very few) shredders effect me in such a way. Maybe because fast playing is exciting, but when everything is exciting. How do you know it's exciting when you can't compare it to something relaxing (or any other effect)? Or when there are just hundreds of notes pushed together, I'm reminded of the saying "sometimes less is better". Alot of those guys just overdo everything. And when you overdo something the character suffers, and if the character suffers the interest in what is going on goes down the tube. I would enjoy shredding much more if suching soloing was placed in better musical situations, and not overdone when it is done. Theres just so much more to music than being technical. Music is an art not a decathalon and music would be much better IMO if musicians would stop making music a competition of "whos faster" or "who's the best technically". Instead have more music that has expression and covers the full range which this art gives us. That's just how I feel.
