BOSS Katana Air Wireless Guitar Amplifier With Wireless Transmitter

The Ultimate Convenience for Jamming and Practice
With its premium Katana sound engine and wireless operation, the Katana-Air makes it easy to enjoy rich, dynamic guitar tones—complete with advanced BOSS effects—anytime and anywhere. And that means you’ll play more often, improve your skills, and have more fun. When you want to jam at home, there’s no need to set up your big rig or rely on the dry, boxy sound of a mini practice amp. Just plug the Katana-Air’s transmitter into your guitar and riff with great sound from anywhere in the room! Thanks to its portable size and ability to run on batteries, the Katana-Air is an equally great companion for travel, parties, jam sessions with friends, and more.

High-Performance Wireless Technology from BOSS
The Katana-Air features new low-latency digital wireless guitar technology developed by BOSS, providing transparent sound and ultra-quick response without any lag or dropouts. The included custom wireless transmitter plugs into any electric guitar, and has indicators for power and battery status. A convenient docking port in the amp charges the battery in the transmitter, providing up to 12 hours of total playing time per charge.

Always Ready to Play
Whenever the inspiration strikes, the Katana-Air is always ready to go. It operates in standby mode to conserve energy when idle, and instantly wakes when the transmitter senses motion. This means that you can leave the transmitter connected to your guitar, and then turn the amp on simply by picking up the instrument! And when you stop playing, the transmitter returns to standby mode to conserve your charge. In addition, the transmitter automatically establishes the optimum wireless connection when docked for charging, so there’s no complicated setup required.

Premium Katana Amp and Effects Tones
Equipped with the same tones and sound-shaping controls found in the performance-class Katana amplifiers, the Katana-Air offers inspiring sounds for any style. Five unique amp characters provide a wide range of tones, from sparkling clean to BOSS’s custom high-gain Brown sound. There’s even an Acoustic character optimised for playing acoustic-electric guitar. The amp also provides integrated access to over 50 BOSS effects, including mod, delay, reverb effects optimised for the Katana-Air’s stereo speaker system. And with six onboard memories, you can store and recall your favourite amp and effects setups at any time.

BOSS Tone Studio for iOS and Android Devices
The wireless Katana-Air is made even more powerful with its support for external wireless operation via Bluetooth. Available for both iOS and Android devices, the dedicated BOSS Tone Studio app gives you complete control of the Katana-Air right from your smartphone or tablet. You’re able to adjust all the amp’s panel controls, and get exclusive access to effects types and routings that are only available from the app. You can also save setups to the amp’s memories, organise sound libraries on your device, and download free patch collections directly from BOSS Tone Central.

Listen to Your Favourite Music and Play Along
The Katana-Air is a true stereo amplifier with two custom-tuned speakers and up to 30 watts of total power, delivering big, rich sound for both guitar amplification and full-range music reproduction. Over Bluetooth, you can stream music from your mobile device and play along with popular songs, backing tracks, YouTube lessons, and more. And when you just want to kick back, the Katana-Air performs double-duty as a high-quality mobile Bluetooth speaker for enjoying tunes from your music library.

Music Production and Silent Practice
The Katana-Air also includes a stereo headphones/recording output with guitar cabinet simulation. This lets you directly record pro-quality amp tones and effects in music production software, and enjoy inspiring stereo sound when practising quietly with headphones. It’s even possible to adjust the cab simulation’s mic position with the Air Feel control in the BOSS Tone Studio app.
