Ultra-compact stereo guitar amplifier

Boss presents the Katana Air: An extremely compact but extensively equipped guitar amplifier that comes equipped with a transmitter for wireless operation. The five basic sounds that the Katana Air has on board cover a wide range of tonal requirements, and the amp is also equipped with 50 high-quality effects that provide even more scope for players to sculpt the tone to suit their own individual taste. What is more, the Katana Air can be operated comfortably using the Boss Tone Studio app via the amp’s integrated Bluetooth interface. Thanks to its extensive connectivity, the Katana Air – which incidentally weighs in at just a little over two kilogrammes – is ideal for practice, recording directly to a computer, and for small jam sessions.

Five basic sounds that deliver the goods

The Boss Katana series offers a selection of excellent-sounding amp simulations, five of which have been integrated into the Katana Air. Players can thus choose between an acoustic simulation, a shimmering clean tone, a crunch sound, and two lead sounds, which are easily selectable using the dedicated knob on the amp’s control panel. The Katana Air is also child’s play to operate in every other respect, and it delivers everything that players expect from a “real” guitar amplifier: An EQ section with controls for bass, mid, and treble frequencies, together with a gain and a volume control that govern each of the individual basic sounds. On top of all that, the master volume control sets the volume for the amp’s 30-watt power stage and its two built-in 3" speakers. Since it has two speakers, the sound of the Katana Air can of course be enjoyed in stereo, which means that the numerous on-board effects – including Chorus, Delay, Phaser, and Flanger – sound even more impressive. All this is topped off by six memory slots for players to permanently save their own settings.

The cables can stay at home

The Katana Air delivers two reasons for players to leave their cables at home – but that is not all: The scope of delivery includes a transmitter that provides up to 12 hours of wireless playing time and is equipped with a standby function. The system’s motion sensor thus activates the standby mode when inactive and, when it is not in use, places the system in sleep mode. The W-LT transmitter can be charged either by connecting it to the amplifier or via its integrated USB socket. Besides no longer needing a cable to connect the guitar to the amp, players also no longer need a power cable, since they can also operate the Katana Air for extended periods on battery power without needing to connect the included power adapter to the mains.

A loyal sparring partner for a wide range of situations

There are plenty of reasons to add a Boss Katana Air to your desktop setup, whether it’s for practising, spontaneous jam sessions, or recording to your computer in high quality via the USB port. Its five potent basic sounds that can be enhanced with great-sounding effects, together with easy operation using the Boss Tone Studio app, and the reassurance of having 30 watts at your disposal (plenty of power for small jam sessions) all make this ultra-compact amp a reliable companion for a range of situations.

About Boss

The Boss brand has been an important part of the Japanese Roland Corporation since the mid-1970s and has caused a sensation from its inception, especially with its compact effect pedals but also multi-effect units and other helpful tools for guitarists. The company's single effect pedals in particular are legendary and can be found in almost every guitarist's home. An incredible 15 million have been sold to date. With its Katana series, the manufacturer now also offers excellent amplifiers at a very interesting price point.

Everything from acoustic to Death Metal

Whether you’re looking to record acoustic guitars or Metal sounds, Blues or Funk, Pop or Alternative Rock, the Boss Katana Air has the right sound for virtually every situation, and its 30-watt stereo power stage is easily sufficient to be heard during small jam sessions. The amp’s integrated wireless system and the included transmitter mean that a cable is not needed, which in turn means one less tripping hazard to worry about. The wide selection of effects, which can all be controlled via Bluetooth using the Boss Tone Studio app, ensure clear and easy operation, and the amp’s connectivity has been configured with practicality in mind. Last but not least, its housing is highly robust, so the Katana Air is more than a match for the rigours of use beyond the confines of the rehearsal room and stage.

Great little guy this one...!
Ted.Theo 07.05.2020
I bought this little guy ,cause I wanted a little practice amp with no use of cables, and with a pair of wireless headphones the job is done! Great clean tones and with a little search with the unit effects you get great modern gain sounds, too...Still not got the full 100% of what this amp can do - because of a sudden hand injury-but I tell you this little fella rocks, especially with a good pair of headphones.No problems at all with connectivity or latency, and its a fun home entertainment system too, since you can connect via bluetooth any tablet or phone and listen to music.Great feature also that you can use any backing track you have and adjust correctly the volume so you can jam with it in no time.A bit expensive though, but for the things you can do and the sounds ,I can justify the cost at least ...looking forward to try with an FRFR speaker that Im willing to buy and see what its gonna sound .....for now I just put it in a wooden base (like a small furniture) so that can amplify it's sound naturally....but I prefer playin with the headphones...great feeling overall.Very pleased with the product although I say again its a bit expensive..


Had It For 3 Months Now
LiamNomad 20.10.2018
It's well made and compact from a design perspective, but you cannot get away from the fact that it has 2 tiny speakers that really don't deliver. The 'portability' concept is good and the wireless works perfectly, but at low volumes you can hear your guitar strings chime and at higher volumes the sound is muddy.

I appreciate that Boss has tried to deliver something for us rocking apartment dwellers - but at this price, it really does not deliver once you get past all the gizmos. Instead buy something else 'low wattage' with at least a 10" or 12" speaker plus a e100 wireless kit if that's what you want - as I am now doing.


Useful compact and good quality
JimJordan 11.10.2021
i have it now for two months. Is very convenient and cool. The app is also helpful, you can create your own patches. The only negative i think is the price but it depends where will you use it. I do not like many cables and i use it only to my house. Very good quality and nice transmitter , if the price is not a problem to you i recommend it.


Good compact solution
Alexey Yu 21.11.2023
- wireless system working with active pickups
- a good set of classic effects and amplifiers

- lack of effects loop (not critical)
- suitable floor controller and expression pedal are expensive
- the expression pedal (wireless or connected via a wireless footswitch) can only control volume or the Wah effect, although in other versions you can assign it to the Pitch Shifter and other effects via the desktop application
- very limited effects chain options

As a result, a good portable solution for practicing. Due to strange limitations (mostly software ones, which can be easily fixed with firmware) the device cannot be fully used.
