I can't remember if I chimed in to this thread yet...
I just got my 4004, and yes, the neck is way different than my 75 4001. Compared to almost every other Rick bass I've played, the 4001 is exceptionally thin in girth.
But I LOVE the Laredo neck. Maybe it's the lighter strings, but I find nothig objectionale about it. Sure it's chunky, but by no means a "baseball bat".
I guess I really am not all that particular; I don't mind my Jazz Bass, and I can switch between my various guitars easily-my Dakota has a "chunky" neck for a guitar, and my Mustang is a short scale...
Guess it's another thing, like most aspects of guitars, that's very subjective.
