I never actually learned to play SRV's Pride & Joy. Thought I'd take a little time to do so. Fun to play and great for the boogie/blues thing. Great licks. I think I carry a very 'vertical' approach to playing (ie - very scalar) and playing more SRV these days for fun pushes me out of that to a more horizontal approach to the neck.
I've been noodling around with Classical Gas too. Time is limited since I;m a hobby player now so I don't know if I'm going to take on the full composition.
Otherwise, I noodle out riffs and licks of my own pretty regularly, so there's that.
