Ok.... in (roughly) chronological order
Yamaha BB605 - good value, but noisy pickups. Gone....
Yamaha TRB4ii - still got, mega
Yamaha RBX800AF - first fretless, surprisingly good. Gone....
Yamaha RBX775 - ghastly, neck too skinny and stupid, stupid electronics. Gone....
Fender (USA) Precision Fretless '77 - still got, lovely sound, wish I could play it
Yamaha TRB4p - searched for years for one of these, imported from the USA, hated the sound. Whoops!
MusicMan StingRay 3EQ - still got, well it's a StingRay :-) My main bass I suppose.
ESP Custom Shop J-Five - still got, great passive sound but never quite got on with the Jazz thing. Gone....
Yamaha TRB-1006 - nice, if a bit "soft" sounding. Not sure I have much use for a 6 really
