Don't think I've ever actually "learned" a solo. I've learned a few lick from solos though. I think the first things I started picking up were Tony Iommi licks. I just loved his stuff. By todays standards his leads aren't that impressive. I just always lean more toward "feel" that technical expertise. For the most part I really hate learning other artists work. Sure I pick up a piece here or there. But I've just never been one to say "Cool I can play that song all the way through", I prefer to write.
That which you can not cure,
you must endure!
