As far as production resources, recent long delays in filling orders indicates that production capacity has been long overdue for an increase, whatever it takes. Don't fix that as the limiting factor for opportunity cost. If California VOC limits a manufacturer, get past the limits by doing some production outside California, particularly on one dedicated line tooled up for only one or two products at a time, to improve dedicated setup-process efficiency...
The issue is all in rolling the dice to see what interest could be generated. If you followed the ancient guitar industry practice and convinced dealers to pre-order one each, offering them a promotional cost of $3000 on the first one but no returns, you could do well on a bass targeted at a SRP of $4500. With such increased margin, dealers would be doing discount deals with customers to move their initial allocation, so it is a win-win with customers.
I think the initial run would sell more like 300 to 600 across a two to five year cycle, not 15. The truth lies somewhere between those two extremes. It is always a gamble.
Success is always in how you market the item with jargon and generated image - calling it faithful down to the last detail, exactly like the 1967 with all the bells and whistles, an "instant collectors item" and a "custom shop" item without the long wait until delivery....
Again, just my 450,000 cents worth
LOL! She's going to KILL me......
