I got King Bass prototype 4 , listed on L42 site as being one of Marks basses, though i dont think he owned the prototypes as it was Status that sold them off. My kingbass was used for reviews by the press and was awarded Bass of the year 2002 in one of magazines.
My Status Streamline was built for Kevin Walker, Bass player for Justin Timberlake, it was built to his special specification including minor body alteration , special electronics and a bit of weight added. Kevin never completed on the deal so Dawn Sold it to me ;-)
I was told my Manson Explorer was owned by someone when i bough it , but I forgot who, it had the name MAC in the fretboard now removed as i had the fret board replaced,
My Dad went on tour with the Who in 1982 to work on the video, and worked with John Entwistle editing the post tour video, sadly he didnt take me along or 'borrow' any of Johns basses , a spyder would have been nice.
