Wow! a philosophical discourse! ...
Very interesting indeed ...
For me, tone, like truth, is really very subjective. As most of us here agree, one man's meat is another man's poison.
I think it's simple enough if we can all accept some universally-recognized parameters in the realm of sound to be able to really 'define' good tone. But see, that's where the problem lies ...
If all of us here were given just a Strat and a Fender Twin to play with, I'm sure each one of us will dial in totally different settings on the amp, and probably the same different settings on the guitar. What might sound 'normal' to one might sound too trebly to another, and so on ...
Worse, this is often compounded by other psychological factors such as the 'hero worship' mentality where we put our musical idols up on a pedestal, scrutinize their gear to the smallest detail, dissect their likes in the hope of nailing their 'sound.'
But see, none of our guitar heroes would even lay claim to 'their' tone as being the 'ultimate,' because perhaps they've matured enough to realize that it's really a pointless case anyway.
Have we heard Vai lambasting other metal players because they use 'inferior' products? No. Have we heard him boasting of some unattainable piece of gear that only he can lay claim to? Heck, the guy still confesses to using a DS-1 and/or a TS-9 to boost his amps. Modded or not, whatever ... point is, I'm sure he can sound like himself given anything.
The problem is, some gearhounds embrace their heroes' tones so much, proclaim it as 'truth' and proceed to follow that same road in the hope of ... well, attaining their own 'truth' ...
From a hero worship perspective, it's perfectly understandable ... i mean, who doesn't want to sound like his guitar hero, right? But then again, when you think about it, is THAT really all there is to guitar-playing? Is it about finding the 'perfect' amp, the 'perfect' set of pickups, the 'perfect' cable ...
What the hell do you do with all that perfection?
In the end, I think it takes a mature guitarist to literally shed all his preconceived notions of what tone is, start from scratch and really find his own voice ...
Best case in point ... I can't help but be reminded of Wayne Krantz - another monster player who I'm sure most of you have heard of.
I wish I could post an article that he did about finding your own musical voice. In that article, he confessed as to how throughout his formative playing years, he's always been an avid Metheny fan. He got to such a point where he sounded so much like him ... It could've ended there, see?
But, somehow, perhaps an inner voice made him realize that there seems to be no wisdom in that quest, for the simple fact that it wasn't him ...
So, from there, he discarded everything ... as in EVERYTHING - his gear, totally reworked his playing approach all over again ...
The end result? What can I say ... but it's a totally fresh approach to guitar playing that most of us probably can't touch ... I think his 'Long To Be Loose' album best exemplifies his style. At that time, he was using nothing but his vintage 73 strat through a Deluxe Reverb.
Talk about a complete turnaround, huh?
But see, even as his style gradually evolved to that point, he didn't go around proclaiming that he's 'finally seen the light,' or something like that ... as of this time, I think his gear has undergone some changes again as he shifted to Suhrs (not sure about that)
So, going back to the philosophical discourse ...
If we can all agree that tone is subjective, then we're fine.
If we can just shed our own prejudices and learn to respect other people's opinions, then we're fine ...
Because when it comes to tone, nothing's written in stone ...
