"Led Zep ain't bad" LMAO Nice Uwe very nice. I guess seeing as you have a Jazz Bass now you'll be woodsheding on some JPJ
JPJ is an excellent bassist, very musical. And his songwriting contribution is often underrated with Zep. But neither the sound of his bass nor the way he played ever struck me a inspirational to copy. I find it difficult to emulate him. If you'd ask me play something typical for Glenn Hughes, Geezer Butler, Roger Glover, Jim Lea, Martin Turner, Neil Murray or Gary Thain, I think I could manage, but if you asked me to play a signature JPJ mannerism I'd be dumbfounded. For 2011 I will listen to him more closely though! I liked what he did on the Them Vultures debut though I found it quite different from his approach with Zeppelin.
When I think of Jazz Bass in a rock context I tend to think of Noel Redding, Mel Schacher and funnily enough Ian Hill of Judas Priest first. Hughes has been playing more Jazz Basses of late too.
