All relevent points Carl! I would like to add that if Bass Guitar is only about the "shockwave" then we can throw out all the great Motown Hits basslines that James Jamerson chopped! I am always challenged to play my role as the Bass Player, and with that, I feel obligated to transition from chord to chord as melodically as possible when there is "room" to do so and is appropriate! (Make those guitar guys really miss you when you aren't there!) I love the analogy about "one string" bass playing. If that's how anybody looks at themselves as the bass dude, they should definitely find a job as a drummer that only uses a mic'd-up kick-drum!
Having a Jesus filled day for sure!
