If you start buying cheap copies that takes business away from him and his income might be affected enough by that for him to be in trouble financially.
Is this tongue in cheek. I honestly do not believe Ken Smith has lost .01 cents to this guy. If you want a Ken Smith bass you are not searching ebay for copies costing roughly 1/8 to1/10 a Smith when finished. If you are you really were never looking for a Ken Smith imho. Ken builds a tremendous bass, perhaps in the top echelon of all electric basses. However, I feel he has called more attention to somebody that would never be put in the same breath (besides Luchi's own advertising that is) as Ken Smith had Ken himself not fired this up.
I am talking about this in an economic "general" sense. What you said may apply to yourself, or even me, but out of all the peeps who bought a bass from Luchi that was a Smith copy maybe some thought about buying a Smith until they saw the cheap copy and decided to buy it and upgrade it instead as a cheaper solution. Point is what YOU and I think is totally irrelevant to what reality is and there is no way (or its very difficult anyhow) finding out who is right. In this case, put yourself in Ken's shoes, would you rather feel safe about getting orders knowing noone is copying your basses or if they are, giving you proper credit and income for it, or be left in the dark knowing you may be losing business in the long term? When it comes to your job, and thus, the money that puts food in your kids' mouths, you dont think twice about that kind of stuff.
Personally I rarely buy a bass because I know for sure I want this model by this luthier, and I'm not the only one working this way. Let me put it this way: if I stumble upon a Smith on eBay that Ken is selling real cheap because its an order a person refused or something, will I buy that one at a great price or prefer getting my bass custom made, waiting the time that it takes to do that, and paying the high price for it? No.
Thing is, not all bass players have money to juggle with and when the option comes to buy a bass CHEAP, they do, and thats been proven with not only wishbass and antoniotsai, but with Luchi here as well.
