Key Features

  • 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.
  • 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. 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. This gives you the option to create any tone you desire!
  • Save your Favourite Tones - With six onboard memories, you can store your favorite amp and effects setups for instant recall.
  • Automatic Memory - This part is exciting! When you want to jam with backing tracks and songs, automatic memory switching changes everything. 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 the spots you determine as the video plays.

Boss Wireless System

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. 

Full of Features suitable for Practice, Recording, and Performance

The versatile Katana-Air EX has features ready for you no matter what needs you have. 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.

Could not have asked for a better product

Unbelievable. Small, wireless if required, blue tooth. So many options when linked to the Boss app. Bonus of an amp setting for electro-acoustic.

For the size of it the sound quality is exceptional. I wanted one amp at home to replace three or four and this amp delivers, with a great range of tones and customisable effects. It might not sound important but I've really enjoyed going cable-free, and the fact that it powers itself on when you pick the guitar up to play is the icing on the cake. I'm not convinced the app is fantastically intuitive. I get on with it okay but I'm used to that sort of thing. Someone less tech-savvy might not really enjoy it all that much. I can't really speak for its durability yet but the build quality is good and it seems pretty robust. Oh, it's expensive. Value for money probably could be better I suppose but it was worth it for me.
