I can't imagine that building a factory is California is much better.
Cordoba's California factory is walking distance from Larrivee. If Jean can build a competitively priced guitar in California then so can Cordoba.
It's about the last place I would build a factory mind you given the regulatory climate, but it does have very good access to transit. (air hubs, major interstates)
The market is absolutely crowded by quality American made instruments. Martin, Larrivee, Breedlove, Taylor (especially the re-voiced ones), Rainsong (if you like Carbon Fiber), the newish Gibson J-15 is a very nice guitar assuming one doesn't mind the fact that it sounds like a Gibson, etc.
So where is the value proposition? Other than nostalgia for the 60s and 70s, why should someone buying a new guitar pick an Oxnard built Guild over a new Martin, Larrivee, or Breedlove? Or spend that money on 3 vintage RI built ones?
The only real discriminator is the 12" radius on the fretboard. I was really hoping they would go with 16" like on the imports as I struggle with anything tighter than 15, so the new US built guilds are out for me anyway.
The imports on the other hand, compete very well against anything else coming out of southeast Asia.
Pretty sure my next guitar will be another Martin or Larrivee, or one of the new CH-PA Rainsongs. Like the OP, I think the new Oxnard Guilds are priced over the market.
