Glad l bought it


I bought this amp for spontaneous parking lot jam sessions at work and was really impressed with the sound quality, volume ability and tonal range. My favorite use for it now is actually playing music while having picnics at a local park. I'm so glad I bought it. Great value for the quality you get.

Perfect practice amp for an apartment / shared living


It is perfect practice amp for me, no trailing wires, loud but not too loud and I use it together with my WAZA-AIR headphones from the same manufacturer. When it gets very late I switch to headphones and all the wireless jacks are compatible. I can be rocking out without the rest of my family or neighbors hating me.



Would buy again.


For a desktop guitar amp, great sound, lots of choices, wireless connection a outstanding feature. Highly recommended.



Makes it easy to pick up and play


My 3rd Katana. So I already love the Katana series, and this is the ultimate tool to get you playing more. All you have to do it pick up your guitar and it's ready. That combined with the Ipad/Phone control of parameters really makes it a great little amp. I think it could be a little less expensive however, so 4 stars because of value in my opinion.



I Like it!


This is one of the most versatile, useful things I have recently purchased. Excellent bluetooth speaker to listen to podcasts, I really like how the amp comes out of standby to "on" when the transmitter detects motion! It has a pretty good life span on 8 AA batteries too.



I will recommend this product to others.


Great practice amp. Finally cutting the cord.



I love it


I will be making tons of noise with this item



Love this amp!


I keep it in my living room to run through scales and songs for a few minutes. I also take it out for performances in small rooms. It sounds great and the app is useful. I look forward to Boss adding more functionality to the app, specifically a way to stream backing tracks and control preset changes to the Katana from the app.



The only amp you need!


Say goodbye to tangled cables! Compact, convinient, and produces quality sound. The Katana Air has everything you need to jam your heart out wherever and whenever you're itching for nickel strings. I really appreciate the app that allows you to control the amp through your phone via Bluetooth. The whole system is just very suitable for modern day use. It even allows for individual sessions with an headphone jack which comes in very handy, especially for my lifestyle. It's perfect.



Boss is a major leader in amplification


Great practice amp excellent studio recording tool. The wireless technology makes practice a snap no wires and it holds a charge for hours. Boss has truly out shined all the other manufacturers by a mile. Great tone patches and availability of adjusting every aspect of the effects on board to dialin the wanted tones. I use this amp regularly as studio tone machine that would cost five times for the kemper profiler or fractal amps. Boss keeps leading the way in amplification!
