Description

Boss Katana-Air EX 20-/35-watt Wireless Guitar Desktop Amp breaks the mold of typical desktop amps, bringing you an authentic, stage-style playing experience. With its powerful, wireless connectivity, you can freely move around without tripping over instrument cables. This compact powerhouse delivers a big stereo sound that rivals larger amps while also offering a variety of onboard amp characters and effects to cater to every musical style.

The Katana-Air EX is ingeniously designed with twin 5" speakers loaded into a custom wood cabinet. This configuration generates a full, rich, and resonant sound that is typically only available with performance amplifiers. The bass-reflex port further enhances the amp's versatility, ensuring a tight bottom-end response for low-tuned guitar riffs and electric bass practice.

There's more to this amp than meets the eye. The Katana-Air EX is loaded with sounds derived from the Katana stage amplifiers, dialed in for maximum expression with its desktop cabinet. The five unique amp characters provide tones from sparkling clean to BOSS's custom high-gain Brown sound, along with a dedicated character for acoustic-electric guitar and bass.

  • Powerful desktop guitar amplifier with advanced BOSS wireless technology
  • Rich, resonant stereo sound with dual five-inch speakers, wood cabinet with bass-reflex port, and 35 watts max power
