Yu~ki's bass guitars, as far as I know he has 4 of them plus his wood bass.  (He may have more and I believe he does, so I should look around...)  He has such wonderful taste and all of his bass's are so pretty.  ^^  In my opinion anyway.  These are the basses I know of: ESP AMAZE BASS Body is walnut. Pick-up is Seymour Duncan SJB-1N&B. Before this one, Yu~ki used his Seymour Duncan DJ-90 as main bass.  They both have the same size, weight, etc. <~~ My favorite Seymour Duncan DJ-90 JB type for sub bass. Body is alder; neck is maple; fingerboard is rosewood. Pick-up is Seymour Duncan SJB-IN&B Seymour Duncan DJ-90FL Yu~ki's solo bass because it's fretless. (so it doesn't make that ringing noise when sliding from one fret to the next.)  It's the same as the DJ-90 without the pickguard (I think) and frets. Mavis Yu~ki bought this guitar to break onstage, but realised it had a really good sound to it and he decided not to break it.  So now he uses it to collaborate.                                                             Fender Stratocaster "Ferrari" Yu~ki's wood bass. It's black and he bought it in a music shop in Shin-Okubo.
