Sigh... yes, lots of folks think the same way you do. Talkbass is littered with post like "Why buy a Sadowsky?", "Who would pay 10K for a Fodera?", and - my personal favourite - "My $200 Squier blows away a "insert Boutique bass brand here"!!! And other such nonsense. Guys like Jimmy Coppolo, Roger Sadowsky, Ken Smith, Vinnie Fodera, Cary Nordstrand, and probably couple dozen dozen more I'm forgetting have spent decades honing their craft, and assembling basses that have particular tone for particular players. You are paying for their experience, their craftsmanship, and their intimate knowledge of how the working parts of an instrument combine to produce a musical result. Oh, and if there is a production glitch with their instrument, you send it back and they fix it - for free.
Sorry, your experience as a furniture builder - no disrespect, it is itself a demanding profession - does not necessarily qualify you as a luthier. I'm sure you can make a stunning instrument that sounds just like an armoire should. Fine furniture does not have pickups, frets, truss rods, etcetera. It does not have to sound like anything in particular. And, just because you can make something for under $1000, does that mean you would sell it to me for under $1000? In fact do just that - make 5 awesome basses and sell them for $1000, then see how you feel about it. Add in the realities of having to doing service and warranty work, then consider that you are trying to pay a mortgage. Can you still sell your basses for under $1000? Could you make a living doing it? Would you?
Dammit how these posts irradiate me.
