The bass I'm currently having built, has all the features I like from different basses, but all on the one bass with a few ideas of my own thrown in. So I couldn't buy anything similar without something being missing. These features are not just about playability, they are about the aesthetics too.
So it it worth the money? Well it is to me.
Could a cheaper bass do the job just as well? Not for me, but then again neither could a more expensive one.
Will the punters notice a difference between my bass and a cheaper one? Certainly aesthetically, tonally probably not.
Will I notice the difference? Hell yeah! And that to me is what it's all about.
