Wow ... very nice, Neo! I played one of these neck-thru -body bass guitars by ESP / LTD a couple years ago, and almost bought it. Even though it's relatively inexpensive (about $750) it sounded great, had lots of sustain, and looks absolutely stunning. The 3 smaller knobs are EQ boost/cut knobs (low-mid-high freq), as it has active pickups. That walnut top ... whoa, baby!
Wow, that's a nice bass - love that top; I had a similar one a while ago, which was an Ibanez with the Bartolini pickups, 18v on board and neck through:
I swapped it with a mate for a Spector 5 string, and was probably one of the swaps I regretted. The Spector was in poor shape, but scrubbed up OK - I still need to fix the electronics as the guy whom my mate bought it off had mucked about with it, and (I ddidn't realize when I was fixing his bad solder job) had made it so the battery for the pre-amp was permanently on ... which was probably why my mate was using rechargables inside it (and the sticker was to cover a hole the previous guy had drilled for whatever reason ...):
I'm not sure why my wife says I have too many guitars 
Cheers
Your 2nd song with your son was well done. Your son did well as he had learnt the song off by heart by the looks (couldn't see him reading music at anytime) and his timing with the little shaker was on point! He has an ear that boy of yours
