I think that's awesome. If it's a bass and I want it and I have the disposable cash, I buy it. Sometimes I even do that with guitars, although don't tell the others.
I honestly don't understand why anyone on TB complains about the price. I regularly see prices that shock me, given that the instruments in question are P or J clones that are
assembled by certain persons. There are plenty of basses - owned by people right here - with outrageous price tags, but if someone wants to imagine that a Fodera (or name your fave 'custom' builder) Anthony Jackson is worth 35K, I got nothing to say about it. I mean, think about it: a bass. 35 thousand dollars. It goes "boom boom boom". It's a bass. But I just shine it on because I don't imagine I have anything meaningful to contribute.
So if you watch the video about making the Cliff Williams bass, it's certainly labor-intensive. And it's not like EBMM had an assembly line ready to go to do this stuff. Numbers are limited and proceeds go to a damned fine charity. It was in many ways a labor of love. And no, I'm not going to - I could not - pay 7K for a bass. Any bass. Ever. But if you CAN and you DO, I say this: "Good for you."
I like discussions about these kinds of things, but if all you got is, "That's too much money" then why even bother? It doesn't add much, does it?
I'm glad that things like this happen. It gives us stuff to yammer on and on about. But again, if your only thought is it's too expensive, is that worth typing out?
YMMV, etc. IMHO and so on.
