Fender has upped the ante in terms of coolest materials used to make a guitar amp. The iconic guitar company has released a limited amount of wooden amps made from the U.S.S. Constitution, the world's oldest commissioned warship. Apparently in 2011 a construction crew found a cache of ancient oak beams that were used to build the warship.
Fender then purchased a few of these beams and made two tube amps based on the '57 Pro and '57 Champ models. You can purchase these amps for unholy amounts of money at the NAMM show in California.
