I know nobody here likes Francesco Farerri (me included) but he plays shred with a similar approach to most jazz musicians (most people don't know this but he improvs everything). I think both sound boring without any structured ideas behind the improv... just a collection of ups and downs... He seems to capture what most people hate about the 'shred' genre... however, most players who love 'shred' music do not like Farerri...
Some jazz players are amzing though, I actually consider them to be shredders that play with a different tone and alternative set of scales. Alex Skolnick is an example of an excellent shredder who turned to jazz... but his jazz stuff just doesnt do it for me. Too much theoretical meanderings rather focusing on what actually sounds good to the ear.
