Very versatile amp.
Really fun amp to play with. I got the 100 mkii for very cheap, almost mint and I'm very pleased with it. having the 0.5w and 50w settings are handy for practice. I do use the 50w setting in my flat but turned down so more of the speaker is used.

Genuinely Great
Simply one of the best digital/ transistor amps around. hugely versatile from squeaky cleans to the hardest chugs, especially helped by the huge amount of digital boss and other effects built into the amp. The tone studio on the computer truly unlocks the amp and shines when recording through usb to take advantage of the stereo effects.

The Best Amp HANDS down.
If you're a Beginner to Intermediate Player, look no further, in fact, the only people I DON'T recommend the Katana to, are the people that can afford, and have the experience to hear the SLIGHT differences between this, and the sound of the Amp(s) it's trying to emulate, and even then, your money could be better spent! Get a Katana, you will not regret it.
Preferred Settings + Usage:
It's hard to find a bad setting, but keeping presence low will make your tone nice and warm, especially with some comp and OD.

Exceeds expectations
Just got this yesterday after trading in my Fender Supersonic 22 head. I had not been vibing with the head for a while and wasn’t sure what direction to go in, and I started looking into the Katana amps. Long story short, this thing is incredible. I don’t miss my tube head whatsoever, as this amp does so much more and still feels like a “real” amp (whatever that means nowadays). So many good features (power attenuator, headphone out, effects loop so I can still use my trusty pedals) and most importantly it sounds really good. If you’re on the fence because it’s digital, or solid state, or a modeling amp, or you don’t think it can hang at loud volumes, then I promise you it can. Very happy with this amp!
Preferred Settings + Usage:
Pro tip: use Boss Tone Studio to access the graphic EQ. You’ll thank me later

Love it!
I primarily use my Katana as a clean platform for pedals. I really love the Sneaky Amps (Kato - a web app for 'Sneaky Amps' https://www.reddit.com/r/BossKatana/comments/wr09r6/kato_a_web_app_for_sneaky_amps/)
The link: https://haeckse.codeberg.page/kato/?fbclid=IwAR2sy5W8YclWBBuvoW-QrHBo-6G7gQBIP69dx9rPMKvREc1bd7TvpkKIbjM
I love the Twin Reverb Sneaky Amp or the Fender Pro Reverb with a little grit the best.
I A/B'd my Katana (on 100w setting) and a Strymon Flint spring reverb with my buddies real '78 Twin and we both agreed that they sounded quite similar!

Great beginner amp.
Amazing amp if you're a beginner. Nowhere near loud enough for a gigging musican or someone who wants to play live fr fr.

Great Tones!
Incredibly versatile amp. It really does everything this guitarist could want. One could easily get lost in all the effects. Great for home practice and live performance.
