The majority of the Gibson counterfeits appear to originate from China. Many of these counterfeit instruments show up on auction websites like eBay. Some of these guitars don't represent themselves as the real thing but rather as "copies" of popular models. However, some sellers are trying to fool the consumers by selling guitars that look like exact copies of the high end Gibson guitars. They feature trademarked headstocks and logos, but upon close inspection the guitars don’t feel or sound like a true Gibson, the serial numbers aren’t registered with Gibson, and most are not of good standard of quality overall.
Gibson advises all consumers to purchase Gibson instruments only from Gibson’s network of authorized dealers, found on the company’s website at www.gibson.com. However, if you still decide to look for a deal on eBay, here is the guide that may help you spot the fakes.
Note that counterfeiters move fast, and this guide may be outdated.
