Stage-Class Sound in a Desktop Amp

Katana-Air EX has been engineered to provide an authentic stage-style playing experience in a desktop size. Two custom five-inch speakers are loaded into a carefully designed wood cabinet, generating full sound with rich resonance typically only available with performance amplifiers. Punchy, high-definition tones give you an inspiring platform for honing natural techniques that seamlessly translate to a stage amp setup. The tuned bass-reflex port further increases this amp’s versatility, ensuring a tight bottom-end response for low-tuned guitar riffs and electric bass practice.

Premium Katana Amps and Effects

Katana-Air EX comes loaded with sounds derived from the Katana stage amplifiers, dialed in for maximum expression with its desktop cabinet. 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. You also get access to over 60 BOSS effects, including a wide selection of overdrives, distortions, and boosters, plus mod, delay, and reverb effects optimized for the amp’s stereo speaker system. And with six onboard memories, you can store your favorite amp and effects setups for instant recall.

High-Performance BOSS Wireless Technology

BOSS’s acclaimed digital wireless guitar technology is at the heart of Katana-Air EX, providing transparent sound and lightning-fast response without any lag or dropouts. The included transmitter offers up to 12 hours of playing time per charge, and the integrated motion sensor and standby function conserve energy when the system is idle. This allows you to keep the transmitter plugged in between sessions and turn the system on just by picking up your instrument. When it’s time to charge, simply connect the transmitter to the amp’s convenient docking port.

Wireless Foot Control with the EV-1-WL and FS-1-WL

The optional EV-1-WL Wireless MIDI Expression Pedal and FS-1-WL Wireless Footswitch expand the Katana-Air EX experience, letting you remotely operate functions you assign in the BOSS Tone Studio mobile app. Control volume and wah, change patches, and trigger the app’s practice tools—all with a cable-free connection. Learn more at the EV-1-WL and FS-1-WL product pages.

Versatile Features for Practice, Recording, and Performance

The highly versatile Katana-Air EX flows with all your musical journeys. Built-in Bluetooth® lets you wirelessly edit sounds with the BOSS Tone Studio app and play along with songs streamed from your mobile device. For fresh inspiration, log onto BOSS Tone Exchange to explore sounds created by other users. You can also record tracks directly to computer music software via USB and use the stereo line output with mic’d cab emulation for live performances in direct-to-PA setups. Going further, Katana-Air EX does double duty as a high-quality portable Bluetooth speaker for relaxing and enjoying tunes from your music library.

Build Skills Faster with Powerful Session Tools

Along with its editing features, the BOSS Tone Studio app comes with integrated tools to supercharge daily practice with YouTube video content. Create song lists for quick recall and loop sections for focused study. And when you want to jam with backing tracks and songs, automatic memory switching takes the experience to a new level. Set a clean sound for the verse, crunch for the chorus, and high-gain drive with echo for your solo—and they’ll all change at spots you determine as the video plays. It’s even possible to save your custom switching setups with the BOSS Tone Exchange community.
