At $10,000, the Parker Fly Select Koa costs a lot more than your average guitar - but then this one is far from average. The beautifully crafted instrument (above) is limited to only 25 signed and numbered pieces, and is handmade by master luthier Ken Parker from a single piece of Koa, a rare, indigenous hardwood native to Hawaii. The wood is golden brown in color with dark streaks and a lustrous sheen, and the fittings are all gold-plated. Koa, used by the ancient Hawaiians to build dugout canoes, is a "tonewood," with recognized and consistent acoustic qualities prized by musicians. Just the thing for that custom-made crocodile guitar case from Hermès you've been eyeing.
