You guys are absolutely correct, forgery is a problem. Today, it's relatively easy to "re-engineer" just about anything. I work for an electronics manufacturer, and we found a whole line of expensive equipment (that we have invented and engineered) for sale in China - except that every one of these devices were total rip-offs. Our company is suing. It seems very easy to rip-off unsuspecting buyers.
I personally have made decals of a Fender logo, that looks stunningly like the real thing. But: I would never pretend that my $245 Squier Jagmasters (I got two) are actually Fenders, and I can also safely tell you that I have never ever sold anything under false pretense. I love guitars so much that I couldn't do that. Besides the logo, there are other easy things to identify real from fake: The serial number for example. I once walked into a pawn shop that had a "Fender" Strat for sale, where I could see the scuff marks on the headstock from sanding off the Sqier logo. Even the "Made in Indonesia" imprint was scratched of with what could have been a dull butter knife - When I pointed that out to the store, they kicked me out! (Most of them also deal in guns, so I responded quickly.)
Yeah, pawn shops and Ebay are the playgrounds of desperate people, taking advantage of other desperate souls, who think everything on the net is for real -grow up! I even think that mass-merchandisers (here in the US it's Target and Walmar**) misrepresent the stuff they sell for around a hundred bucks. Anyone with a painbucket and some woodworking tools can build something that looks like a guitar, smells like a guitar -but is not a musical instrument.
Unfortunately the days of an honest handshake and vintage guitars for what they are really worth -are over. If you think you found a good deal on the Internet, do your homework researching and talk with people (like the folks here on Chordie).
Since I've already spent so much money on crap that looked great in the store, I decided to build my own guitars -it's not cheaper, but at least I know that my instruments are made with care, dedication, and a great love for music.
Play on!
