I've come to appreciate tone of specific jazz guitarists more and more...and the influence it has on the overall quality of their music. Certain people have developed very unique tones that are unmistakenly their own. For me, the ones that really stand out are: Pat Martino--thick, almost rubbery quality. very bass heavy, very little treble presence. Pat Metheney--smooooooooth. buttery. lots of reverb and sustain and a very even, almost glassy sheen. John Scofield--a little dirty, always a little bit of flange (kind of irks me sometimes). almost crunchy in ways. John McLaughlin--thin, piercing midrange with a touch of chorus (?) and reverb. Very strong attack that allows him to get definitioninto those blisteringly fast runs. Grant Green--Staccatto yet somewhat fat at the same time. Very strong attack and present midrange and treble, just the smooth side of twang, with a touch of reverb. What are some others? Favorites? note: I realize trying to use words to describe tone is like dancing about architecture.
