Boss Katana Air

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..

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.

Pros:
- wireless system working with active pickups
- a good set of classic effects and amplifiers

Minuses:
- 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.

I bought the amp mainly for home use (my first amp) because it was small and other small amps don’t have so many effects. I’m starting to really like it. Here’s my opinion:

Pros:
Ultra compact
Completely wireless! (Works on battery if you want, but adapter also included, no cables at all)
Tons of effects built in (literally hundreds)
App to change the settings

One little con:
When you are playing on really low volume, you can hear the radio frequency sound or whatever (little cracking noise?)

Overall I really like and the pros really outnumber the con.
