For guitarheads, October is a very special time for a couple of reasons. One is the Arlington Guitar Show, which happens the third weekend. The other is the release of The Official Vintage Guitar Price Guide. You know it as the industry’s leading source of pricing information on vintage and recent-model guitars, amps, basses, effect pedals, mandolins, lap steels, ukuleles, and banjos. (Free Shipping in U.S.; $12.95 in Canada, $14.95 in all other countries).
