It's one of the better budget options out there. There's a reason a guitar center I went in recently had a stack of these 5 high in the center of the main room, they are quite popular.

I'm using the Katana and I'm abslotely loving it. Just one thing. If you don't have the ability to connect it to a computer with an USB, you'll miss out on a LOT of the features it has.
Praise
The 50 not having an fx loop is a huge weakness, would be such a great looping platform with that.
Complaint
Katana is about the most recommended amp here if you glance through the hundreds of posts asking the same question

The Katana by itself is a fairly generic modelling amp. When you hook it up to the computer you get access to a wide variety of virtualized effects pedals all based on the different effects pedals the Boss offers. It's almost analysis paralysis inducing. Ultimately the insane amount of options it offered actually made me dislike the amp because it seemed like you had to do a ton of work just to dial in a semi-decent tone.
Complaint
My only thing about purchasing a 50 watt amp, is that it was very loud when practising by myself, and not loud enough when gigging, as my band mates all had 100 watt amps. I've heard great things about this amp, though haven't one personally.
Complaint
People who say it doesn't do distortion well haven't tried very hard, I play mostly modern metal tuned to drop f# on my 7 string with a fantastic distortion tone dialed in. Tight low end and a clear high end. Couldn't ask for a better amp for what I do.
Praise
I've had two of those (one I purchased, one bundled with a trade) and a katana and I thought the mustang didn't hold a candle to the katana.
Comparison
As you may have noticed, those who do recommend the Katana Mk2 advise you to go for the 100 watt model. So here's the thing: because you need the 100w version to use the GA-FC footcontroller and have the fx looping option available, these 50 watt models often get traded in and become B-stock at a lower price. So if you do decide the 50 watt model will suffice DON'T BUY A BRAND NEW ONE! Shop around for cheaper B-stock. If the price(drop) is right, it's a mighty sweet practice/bedroom amp and combined with the tone studio a cheap way to experiment with different kinds of distortion, modulation, FX, delay and reverb.

This video is running the amp Miked into a PC more than likely. Miked amplifiers wont give any representation of in the room sound. YouTubers should really use a far field mic at ear level, best thing I can tell you is dialing your tone with headphones on then use the amp off the ground or as the very least angled upwards
Mention
Have you seen that video where Anderson's replaced the katana speaker with like 7 or 8 other speakers? Might be an option there, they concluded that the Katana speaker wasn't the best for high gain tones. Fizzy and somehow lacks all the bass you hear in cleans
Complaint
I own a LT25 due to budget restraints at the time, I wish I went with the Boss Katanna. The LT25 doesn't sound bad at all but 50 vs 25 watts and the fact the Boss Katanna has way more preset options, you can also download custom presets online made for specific songs.
Comparison
The speaker in the 100 is considerably better too. I had a few friends use the 50s for some gigs, but they all upgraded the speaker. I got a 100 for basically the price of the upgrade and installation, and had an amp with more functions and I used it stock for some grab and go gigs for a while. Adding the GA footswitch was a big plus too.
Complaint
As an intermediate player I love how much the Boss Katana offers for the price - it has a great variety of effects and good-to-great tones ... However, I notice a huge quality difference in the high-gain/boost tones when playing through the cabinet speaker vs my headphones. To me the best way I can describe the difference is the cabinet speaker has too much of a 'fuzzy' sound, whether I'm using distortion or overdrive.
Complaint
✅ What Works
- Praised for value — huge variety of effects and tones for the price
- Clean tones and preset options well liked, with downloadable custom presets
- Better feature set than budget rivals like the Fender Mustang LT25, per several owners
⚠️ Worth Knowing
- Stock speaker described as "fizzy" and bass-light on high-gain tones
- Some owners upgraded the speaker or moved to the 100W model for better sound
- Deep menu of effects can feel overwhelming — some found it hard to dial in a good tone
- USB connection to a computer is needed to access much of the amp's functionality
ClearPick Verdict
Owners are broadly positive on the Katana-50 MkII but flag real limitations. Of 14 mentions, 7 are positive, 4 mixed, 3 negative. The top complaint is the stock speaker's performance on high-gain tones — described as "fizzy" and lacking bass, with several owners upgrading the speaker or noting the 100-watt model's speaker is "considerably better." Fans love the sheer variety of onboard effects and the price-to-features ratio, though a few found the deep menu of options overwhelming rather than helpful, and note the amp needs a USB connection to unlock its full feature set. Good for bedroom practice and experimenting with tones on a budget; players chasing gig-ready high-gain tone may want to budget for a speaker upgrade or step up to the 100W model.
