Hold on, let's back up:
What I read in this post, before your explanation above, didn't make sense to me. I see what you're saying now about rock vs. jazz guitar tonalities, and the attitudes that each group brings to the process, and agree up to a point. I think Al Dimeola's rock tone has always sucked, and it can be hard to tell a Peter Bernstein from an Anthony Wilson. However, you also have to consider what the music wants. If you're playing what is primarily acoustic jazz, it would be really difficult to make an argument for having a distorted tube amp blasting away. It's a balancing act, and I haven't found a perfect solution to the various needs that my musical situations present as of yet.
I think Metheny is a good example of someone who has "exploited the qualities" of the guitar (and technology in general) in service of some forward thinking music, which is why the last sentence of your post made no sense to me.
BTW, I used to get an awesome metal tone back in the day, if I do say so myself. Straight into a beautiful tube amp, run cleaner than most metalheads, but crunchy. And LOUD! :rsmile:
