WHAT IT IS: These custom-built guitar amplifiers are made from vintage toasters, fitted with a six-inch Jensen speaker and custom-painted by a hot-rod detailer. Powered by a 9-volt battery, Hotties are the coolest practice amps around and can be hooked up to an external cabinet for even more volume.

WHY YOU WANT IT: Hottie Inc. founder Jean-Claude Escudie, also a VP at Breedlove Guitars, can barely build enough of the custom toaster amps to keep up with the demand from those coveting his product, a group that includes big rock stars and legendary guitarists.
