Everyone should check out this youtube clip as it features one of the sickest slap bass lines in history being played pretty close to perfectly on a Rick 4001. Major props to this guy! Very nice job! I had a 1980 4001 almost exactly like the one in this video (Burgundiglo) and I got rid of it because I wanted something more slappable. Bad decision all the way around that I have regretted ever since. Enjoy! Cheers!
