most of what i focus on these days is improvisational lead guitar. lately i've been really trying to get the tone right. a little bit of chorus or reverb plus a good wah (zakk wylde crybaby is my current fave) and years of just piddling around can go a long way in terms of getting some good stuff out there.
i'm pretty sloppy but lately kicking out good stuff howling with emotion hasn't been much of a problem. my big issue is creating compositions that have the same kind of emotional power.
soloing is easy once you have a few techniques down, its just one part of a much more important machine.
