Sounds fairly generic, until 1:04 when the flautist walks in, plays a little melody, then goes berserk! Mr Williams was clearly a massive Jethro Tull fan.
Actually it's 5 string and while the neck is lost in the glare it looks like the tuners are at the bridge end, making it headless. On the right track?
A 5 string headless at least narrows it down a bit, and it's not Status-shaped.
I love Tomita, ever since I first borrowed his "Snowflakes are Dancing" from the record library in Birmingham. But he is a bit odd at times, and this arrangement is definitely one of those times
I use a tuner pedal, then usually DI into the desk. Anyone with a passive bass uses the Behringer BDi21, either just as an active DI to buffer the signal or as an amp modeller. Cheap and cheerful, but actually pretty good.
