The Boss Katana-Air guitar amplifier is a modern marvel that requires neither cables nor outlets of any kind to play. Its petite size makes it portable and the standby mode makes it ready to go at a moment’s notice. The amp runs on batteries for 12 hours at a time and uses motion sensing transmitters to communicate with the instrument, which gives guitarists plenty of room to move while they play. File this amp in the really, really want column.
