Personally, on a lesser known scale, I'd like to get lessons with Jay Terrien. His sense of humor and his different but very chill style of playing bass are very cool and impressive. http://www.grasstain.com/home.htm is his site. On a larger scale, I'd like to take lessons with Stuart Hamm. His Slap, Pop, and Tap and second video arevery cool, and he's a superb musician. I'd also like to take lessons with Marcus Miller...a man with such groove! Very awesome guy, favorite slap sound no doubt. For the progressive side of things, albeit John Myung might not be able to teach well (I've heard nothing but bad things about his instructional video) he's good at bass. I'd also like to learn from Michael Lepond or Thomas Miller from symphony x. Who are some bassists you'd like to take lessons from?
