I'm being harsh, Jaco is awesome, but of course there are others, Pino, Tony Franklin and a whole host of others who have dabbled and come up with something beautifully creative.
My point is, however, that all "budget" fretless basses appear to think we want to be Jaco clones rather than individuals.
The standard is, especially for fender styled instruments, has become the stereotypical sunburst jazz bass, now usually with a lined fretless neck.
I like jazz basses, I like p basses, I don't like sunburst finishes and I'd prefer a non lined neck! Arrrgh
How about a simple squier pj in black with an unlined neck? Franklin style? Or a Jaco noir? Red? Natural....Surf Green?.... don't know maybe I'm on my own here.
I have a tatty old hacked about ibby roadster fretless maple neck in white, it's great but I'd like to match the rest of the collection somewhat as it stands out like a sore thumb...maybe a refinish is in order.
