hey David.... I'm a new beginning bassist, former guitarist(almost 2 years). Anyway, I just completed Alfredo Grado's beginner course over at workshoplive.com and have now started digging in to your rock course. I live in an obscure little town and good bass teachers are hard to find around here. I just want to say that workshoplive.com has been a godsend for me. I looked at a lot of online content for bass and workshoplive has been the best thing I have found. Everything about it is of the highest quality. I hope they continue to grow their portfolio of bass lessons. I don't ever want to run out of material over there. Thank you!
