useful to try pedals and stuff but..

it just sounds too digital too me, it doesnt have any personality and sounds like if you plugged your guitar into a programmed speaker (i mean that IS what it IS). it just sounds sterile, the program can be a bit clanky and outdated and if you really want pedals and amp sims use an interface with a program instead of an amp that is a mediocre multitool which doesnt excel at anything.. no warmth, no personality.

Good for beginners, don't recommend beyond that

I've not particularly had a great time with this amp. While it wasn't my first I've had it a long time. It's always been second fiddle in my collection and I really only use it because I A) don't have a great clean amp and B) don't have as many pedals as I would like. Being a modeling amp, it really does not take well to pedals, which became a big problem when I realized I can't open up my sound in the ways I want without them. I have to use a buffer pedal with it because otherwise the output will be weak if your signal chain isn't direct into it. This amp is also a nightmare to work with if you, like me, never had access to a Windows capable machine of any description. You need Tone Studio to finagle decent sound out of it because the panel alone doesn't give you wide enough access to parameters. The only thing I really like about this is how easy it is to get a Mesa Boogie-esque tone out of it. But I'd much rather have a Mesa Boogie to work with instead.

Best seller for a reason

This amp is incredible. It has endless sounds in it, it's easy and intuitive to use, it's cheap, it's small, it's light, it's loud, there's very little not to like. If I were to get it again, I'd opt for the 100w version that has a different speaker, but that's not to say the speaker in the 50 isn't good, just different. Since I've got a Orange Rocker 15 Terror, I've mainly used the Katana with a Dirty Shirley overdrive pedal or Big Muff to blend in with the Orange, and it excels at filling out the sound.

A screaming deal

I bought this on the spot at Guitar Center, schlepped it home, plugged it in and cranked it up. Within five minutes, my wife begged for mercy and ordered me to plug in the headphones.

I got sounds out of my guitar I never knew were possible. The sound packed into this compact amp are amazing, and I really haven't fully explored all the options.

I mainly use this amp to practice at home, but I know I could use it at a gig if I ever got one at a club.

The clean setting is superb, and the crunch and brown settings really rock. There's even an acoustic setting, and my Taylor sounds great coming through.

You can also sync it to a computer and get a variety of presets that are fun to mess with. There's a Mark II version out now. Do I wish I had waited? No. I'm very happy with what I have. With the Mk II out, these originals will be an even less expensive proposition, well worth snapping up.

Amazing Value

If you are thinking about something for starting out on electric guitar it's hard to go wrong with this amp. The tones are great for the cost of the unit, and the number of effects will let you explore effects without spending a fortune on pedals. You could really get away with gigging with this and many have. If you are a professional musician this makes a great practice tool and way of trying out ideas. You can play this quiet or loud. The software takes a bit of getting used to but once you get it - it's a very complete app that unlocks the effects and lets you tweak and stack them. Pretty hard to beat for the money.

Amazing amp

Lightweight, portable, and also loud enough to be heard over a drummer. Best amp I've ever played. If you want a flexible amp that can get tons of tones, this is the amp for you. The controls make it easy to switch channels & EQ your tone, & the onboard effects provide loads of options without the option paralysis of similar amps. No more scrolling through 100 menus just to tweak your tone. The Katanas also come with Boss's Tone Studio software, which includes a ton of classic effects including all the Boss pedals, a Tube Screamer, ProCo Rat, Big Muff, Flanger, Phaser, and Korg SDD-3000. There's way more effects, but those are just a few. The Tone Studio software is super easy to use, and you can easily share patches & presets with it. In addition to the multitude of great features already mentioned, you can also change the effects chain in Tone Studio so you can put delays in the effects loop even though the Katana 50w doesn't have an actual effects loop. Absolutely no complaints whatsoever about my Katana 50w, it's an amazing amp & I absolutely love it. I can't recommend it highly enough, it's great for any genre & any type of player, from beginner to professional.

A great budget gigging or practice amp

After getting this amp recently I must say I am very impressed in many ways.

Positives: The first positive is the way the amp was designed. It has great power scaling options allowing for greater versatility. In addition, the acoustic channel also adds another function to the amp that works surprisingly well. The tilt stand does a good job directing the sound in a pleasing way and many of the onboard effects are actually very convincing and sound very nice such as the chorus, the delay and the reverb. In terms of pure amp sound, the clean channel sounds very clear and pristine and is a fairly good platform for pedals. It has a more trebly sound which would be great for cutting through in a live context.

Negatives: The clean channel is excellent however the rest of channels leave a bit to be desired. They are all highly bright and lack bass end, making them highly un-compelling. In addition, many of the effects are useless and some sound good alone but don't work well with pedals. In addition, the speaker itself definitely has issues working as both an acoustic and electric guitar speaker as it often exemplifies the highs too much with electric guitar.

All in all, it is a great amp for £165 and certainly ticks all the boxes as a gigging work horse and a worthy Cube replacement.

Best Bedroom Amp.

This amp, in my opinion, is the best practice amp for the money. Sounds great and is small but loud enough.

Very portable, sounds good

It's great when you need a light amp. I get good tones for jazz on the clean channel and I downloaded a Fender Deluxe patch that sounds pretty nice for blues jams.

Preferred Settings + Usage:

Decent practice amp

Lots of options to tweak tones using the software while connected to your computer via usb, but not the most tweakable using the amp's hardware alone. Sounds pretty good and gets pretty loud. Would be nice if they included the foot switch with it like the 100w version.
