A good friend of mine who has for years been working in the guitar-industry told me that actually about 90% of all guitars worldwide are produced in only a handful of factories in china and korea.
So when you are looking in any musicstore you are quite likely to see a cheap 100 bucks no-name guitar hanging right next to a 2000 bucks well known brand guitar that have actually been produced in the same factory somewhere in the P.R.C.
The quality between the 100 and the 2000 bucks guitars DO differ nontheless. Especially for the very cheap models the amount of crap-guitars is quite high and quite a percentage of the guitars imported have to be returned for poor quality. One of the more common reasons is that they quick-dry their wood for the cheap guitars or they just take wood that has not been properly dried at all. So while the guitar looks good when they produce it, it might have twisted itself into a pretzel when it arrives a few weeks later in europe or america (or elsewhere).
