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.

So simple and easy

What is your opinion of this product?
Great sound, super small, built in wireless. Even hibernates when not in use after a little while. I’m living and traveling in an rv and this fits perfectly in the entertainment cabinet and projects very well. If this stopped working today I would buy another immediately. Works with phone or tablet as well.

Rock out with your rooster loose!
What is your opinion of this product?
I was sceptical about how 2-3" speakers would sound, but damn I'm impressed. A little pricey but was well worth it. The bluetoof app could use some work though. But who cares it's wireless. It's like your mom, I can pound it all day and she don't bruise. She's loud and obnoxious, and a little bit screachy. And she cleans up nice when I just turn my knob away for a while. You should definitely have one of these for everyday practice. Don't be a fool, use this tool.

If you understand this thing is primarily for rehearsing, then you can you understand how amazing this little amp is. The wireless capability is amazing and the ability to edit your tone via Bluetooth on your phone is really cool. Can’t beat the price and the quality.

Oh well, great idea, not so great quality
What is your opinion of this product?
I was very excited about this when I read about it in NAM coverage. However, I boxed it up after an hour to send back. In my opinion this unit should be about ½ of it's $400 tag. I was unimpressed with the build quality. I thought I could justify the cost because it was also a bluetooth speaker, but it sounds muddy and cheap. It's advertised as 30 watts plugged in and 20 on batteries, but I don't agree. It's volume is much less than most 30 watt solid state amps. This is a great concept and some of the guitar sounds are good, but it's WAY overpriced!
