My pholosophy toward guitar is that being a good rythm player helps your leads, and being a good lead player should help your rythm. It's all got to work together, and I really feel a need to know both- afterall, both have their place. Afterall, a large part of what made SRV so great was that even when he was playing a lead, it was very rythmic, and filled a lot of space. Now of course, I sound nothing like the man, but I try to keep that in mind.
