i always thought the bass on "jam on it" was the 303 (might even have read it on this forum), but i just stumbled upon a gear list posted by cozmo d ... it said they used the pro one on that album, so now i'm thinking: could also be the pro one ...
the intro has that drifting sound of 2 detuned oscillators which would mean it's a pro one ... on the other hand, the bassline sounds sequenced, so 303 after all?
any opinions?
