"What I don't care for at all is when guitar players only know tab, and don't know what the hell they are doing theoretically. That leads to no sense of timing, scales, chords, difficulty trying to relate to other players musically, no direction whatsoever when writing, etc... Just a bunch of "shredding" going nowhere."
Hm? You don't need to know standard notation to know what you're doing theoretically. I admit I'm not very 'notation-literate', I can figure out notes if I'm given a minute or 2, but I don't recognize chords or scales or anything like that. But that doesn't mean I don't apply theory to stuff I write. I've used the 12 tone circle, (I know that's not 'established' theory, but it still is a form of theory.) The timing part I can somewhat understand. Notation would be easier, but that doesn't necessarily mean a tab-only reader isn't going to be able to distinguish eighth notes from triplets or whatever. You can still recognize chords and scales in tabs, too.. The shredding part I can't really relate to- I'm not really at 'shred status' yet.
