I've been playing guitar since the early `90s, and just like in the world of knives, there is a certain correlation between country of origin (both materials and construction) and build quality. When I started playing, a lot of today's big name brands were either true custom shops or build-to-order only, usually through dealers; Jackson, Schecter and ESP are prime examples. I liked Jacksons best, and have owned at least a couple dozen of them over the years. Not everything they built was perfect, but generally speaking, any Jackson built in the USA or Japan was of high quality. When they switched to Indonesia, India and then China, both the sourced materials and actual construction suffered. The most I ever paid for a USA Jackson was $1400, and it was beautiful . . . but I ended up hating how it played and traded it away. That was in 2001. The next time I bought a brand new Jackson was probably in about 2005-06 and was a pre-order from Japan, which cost around $450. I picked up a couple more since then, but mostly used or on clearance. Now days, it would cost over $1000 to get a Japanese Jackson of that quality level, and $2500+ for a USA. The difference was, a production line model then was often offered with different types of body and fretboard wood, inlays, and pickups, all for production line prices rather than custom. The same guitar could be had with a mahogany or ash body, and maple or ebony fretboard, for roughly the same price as an alder body with rosewood fretboard.
My most recent guitar purchase was a Schecter AW-7 (seven string) that cost $800 and was built in Korea. Normally, I wouldn't have bought a Korean guitar, but it had a beautiful stained mahogany body, ebony fretboard and all the features I wanted. There is no current American or Japanese production model with those specs. I don't care for a lot of Schecter designs - they are sort of the CRKT of guitar makers to me - but when they get it right, they REALLY get it right. Also, I think there is a certain pride in workmanship among Korean builders that rivals that of Japan, which is to say it's incredibly high. I haven't found an Ibanez or ESP that is on par with an earlier Jackson or current Schecter.
Then again, I play in a metal band, so I'm not paying attention to some of the other brands out there.
