"The bass sound on "Continuum" is pretty special. Can you tell me how that one worked?"

"I played the whole tune twice, note for note—that's how I did it. Everybody thinks I've got all sorts of electronic gear, but I don't use any pedals, no electronics." Jaco Pastorius interviewed by Tony Bacon in 1976.
