Sounds like reasonably fresh nickel roundwounds to my ear on my PC sound system, which is pretty good.
While I dig the tone on that first clip a lot, my guess is, once you get out into the audience, the top end totally disappears. As I always post, it's amazing how much presence you have to have in the upper mids and treble to put a full range tone (especially when slapping) out into the house (which is why it's relatively rare to see a guy playing that style having an alder/RW bass). However, with the close-up mic'ing of that clip, it sounds very nice to me... that nice, polite alder/RW slap tone that is really warm and organic. Again, not totally my thing, since that tone gets eaten up pretty quickly in a mix for that style of playing, but if you have good front of house and/or a LOT of watts, it can work pretty well.
