Mark - you're absolutely right about the heavy boom and the light chuck, and not sounding like a whole band. I need to reinforce that with the guy.

Russ - Actually the guy does know that boom chuck is the standard - his comment was "I know that's the way it's normally done, but what would happen if you did two single notes?" - Unfortunately he's not that proficient yet in getting a good loud bass with either thumb or flat pick,so its going to be a while before he's able to hear the difference. The guy is quite bright, about 45 years old, and very earnest about learning. Just got some bad habits to overcome.

Annie - I hadn't heard the "dumb chick" aliteration. Since I play in a band with two pretty outspoken and modern women, I don't think I'll use that too often :) !!!
