The Official Vintage Guitar Magazine Price Guide continues to be the industry-leading reference for values on vintage and collectible guitars, basses, lap steels, mandolins, ukuleles, banjos, amps, and effects. The 2016 edition spans 640 pages and includes detailed information aswell as current pricing (in ) on more than 2000 brands and more than 1,300 photos, plus a detailed look at the hows and whys of the collectible instrument market. This guide is the only such work to cover all this in one very affordable volume!
Before buying or selling a guitar, knowing it's value is important. Guitar values can range from practically nothing to an astronomical sum for the right guitar - and to an untrained eye, guitars at either end of the spectrum can look very similar. Once you have correctly identified your guitar, you can look up a suggested value in the books above.
Please note, I get a lot of valuation questions, and will only respond to requests made on the vintage guitar forum, with detailed images uploaded as attachments.
