Pros: Excellent sounds, flexibility, build quality and volume. 4 channels so easy to use with a looper using a different tone.
Cons: No footswitch or USB cable supplied, no tuner, and mono only. Connections apart from instrument in are on the rear.
Recommendation: buy one before Boss change their minds!
I have had this amplifier for 2 months now, and I am still as in love with it as I was when I first fired it up.
God's teeth is it loud - I also own a Fender Mustang 3 V2, which I very much like, also 100w. But heavens the volume from the Boss has to be experienced to be believed. I am running it on 0.5w in the house and that is plenty (standing too close is not to be advised!). The build quality appears to be excellent - it's definitely a premium product. I had to update the firmware before using the Boss Tone Studio - a bit of a complicated process but easily enough done following the instructions carefully.
I've played all my guitars through it now, but usually use my acoustic Yamaha APX700 and my Epiphone Prophesy GX, the former using the acoustic pre-amp setting and the latter all the others. It has a much fuller tonal range than the Mustang, which can sound a little thin at times. The acoustic pre-amp is one of the main reasons I chose to buy this amplifier and it does not disappoint. Despite the relative simplicity of the controls there is a huge variety of tones available, all of them frankly excellent. The praise heaped on this machine for the brown sound is not misplaced. it's staggeringly good - as are the others. As I have grown more used to the amplifier I find the dynamic response of the crunch sound in particular is especially good. It really is simply excellent. The complimentary software is a little unintuitive, but works well. I've created my sounds which are now stored in on my laptop as a set.
The clean pre-amp takes external effects brilliantly, my Zoom G3X sounds better than it has ever done before.
I am giving 5 stars everywhere, because it just sounds so good, despite the niggling negatives: the amp is mono*, there is no foot switch supplied and there is no tuner. And it is a bit pricey compared to the 1x12.
I now have a GA-FC which makes using the amplifier far simpler and enjoyable. The channels switch with very little delay - instantly for all practical purposes. Just a wonderful and wondrous machine.

Result after a 1/2 year

Ong Map, 03.02.2018
- since 1/2 year I use the Katana 2/12. He is only used on Sundays in the rehearsal room. Not anymore, since I am now going directly to the PA with my boss GT10. The reason = less to carry, nothing more.
Also I had the problem to bring the associated program on the computer to work. However, the problem has been put into perspective, since it only works under Windows7. No problem at all with Windows 10 (and I'm really not a PC freak). With the program God knows how many effects from the Katana can be conjured and edited. Chorus, Flanger, Rotary, Tremolo, Reverb, ....- everything you need is there. You can then assign the effects, if you like, to individual channels. In addition, you can with the foot pedal (extra purchase) to select the whole with foot switch. The foot switch works a bit confusing.
Although this is a transistor amp, it is also loud enough for gigs. Finally, you go with the lineout still in the PA. A colleague of mine has the Katana 12, so the same part with only 1 speaker. It seems a bit louder, though smaller.
I can say the following about the sound:
If you like a nice clean sound like the Fender Twin Reverb, you will not find it worth its while. He can not do that! Not even with a Fender Stratocaster. The katana can be clean, but somehow different, warmer. Anyone who wants to play an A-guitar over here and there will be super satisfied, sounds class. However, the cream is the sound of a Gibson Les Paul, really cool. You have to want to play a bit louder and of course a bit tense. Katana can do that really well. Of course my Stratocaster sounds good at this setting, but the Gibson is a whole lot better.
For me, I would not buy it again, maybe that's because I still have a Fender Twin and a Fender Champion100. However, my Paula does not want to miss him anymore :)
