World Record Bass is having a teleclass with Bill Murphy and another with Bob Crupi. Might be worth the investment in a long distance call. Here is a link.

I saw the post on the www.worldrecordbass.com board about the last teleclass and most of what they said seemed to be info from Murphy's book. Nothing really new. But I shure if you and I listened we would each pickup different bits of useful info.
