Going out on a limb here - I think the bassist looks more like Chip Douglas than Jim Pons. If it is Douglas then it sure looks like a '66 "Sweet Spot" Starfire I bass. I think Pons played a Starfire but he also played a lot of other basses. I don't think this is a Gibson EB-3 because I am not seeing a neck position PU but whoever shot the video was not expecting gearheads to scrutinize it 50 years later.
