As you may have guessed from the name, the Katana Air is being hailed as the world's first truly wireless guitar amplifier. This doesn't just mean a battery-powered amp with killer guitar sounds - it even comes with a guitar adapter that allows ultra-low latency cable-free jamming! Read on for the full lowdown!

Redefining Wireless

It's true that wireless adapters are more commonly associated with live performance - you may have never considered having one at home. Luckily, the kind folks at Boss have got you covered, offering this functionality as an included bonus with the Katana Air.

Making use of newly developed Boss technology, this goes beyond simply not needing a power socket. The included wireless adapter plugs into any guitar, delivering a pristine, low latency signal that gives you the freedom to enjoy wicked guitar tones anytime and anywhere with up to 12 hours of playing time! 

Not only that, but the wireless transmitter has a built-in motion sensor - it turns the amp on as soon as movement is detected. This allows you to leave it plugged in when the amp isn't in use, so the minute creativity strikes, you can pick up your guitar and be in full swing immediately! The amp will then return to standby mode to reserve power when idle - saving you the time and hassle. To re-charge the transmitter, simply place it onto the dock that's attached to the amp and it'll be ready in no time!

Top-Class Tones

As with the rest of the Katana range, the Air boasts premium sounds that are guaranteed to suit any style. Whether you're after country twang, seismic metal riffage, or any of the vast in-between, it's got you covered! 

Five uniquely versatile amp characters cover a huge tonal palette. On top of this, you have access to over 50 Boss effects from modulation to delay, each of which is optimised to work with the Katana's powerful stereo speaker system, so you'll be able to harness the full potential of the Boss FX selection! 

You also have six user presets at your disposal, allowing you to save your favourite sounds and effects and recall them instantly with ease. You can also make use of the new Boss Tone Studio App for iOS and Android, allowing you to tweak your sounds to the finest detail while on the move - then you can connect your device via bluetooth and your tone is pre-dialed!

Here's what Boss have to say about the Katana Air:

Meet the Katana-Air, the world’s first totally wireless guitar amplifier. Featuring new cutting-edge wireless guitar technology developed by BOSS, the Katana-Air gives you the freedom to jam and practice without hassling with guitar cables. And with support for battery operation, there’s no need to plug into AC either, so you can literally play anywhere!

Though compact in size, the Katana-Air is serious about sound quality. Equipped with pro amp tones and effects from the performance-class Katana amplifiers, this wireless wonder delivers premium guitar sounds for any style of music. To further extend the cable-free experience, you can wirelessly edit and organize sounds with a dedicated app and jam with songs streamed from your smartphone. With the innovative Katana-Air and your favorite axe, casual playing has never been more convenient and inspiring.

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 optimized for playing acoustic-electric guitar. The amp also provides integrated access to over 50 BOSS effects, including mod, delay, reverb effects optimized for the Katana-Air’s stereo speaker system. And with six onboard memories, you can store and recall your favorite 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, organize sound libraries on your device, and download free patch collections directly from BOSS Tone Central.

Listen to Your Favorite 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 practicing 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.
