Great Little Amp
Boss can thank Ola Englund for why I purchased this great sounding little amp. Ola Englund is a guitar player and works for a guitar manufacturer in Europe. He has his own YouTube channel with a series called "Will It Chug". Ola did a nice video on this product, and Ola is the reason why I decided on getting this little amp. I'm not trying to plug Ola. This is a material fact statement, I bought this product because of Ola. This little solid state amp sounds great for it's size. it's so loud, I never cranked it up. The built in distortion is OK, but it sounds great with my BOSS Metal Zone pedal. I love the digital delay sound on it. The amp does have a slight tinny sound to it, but it still chugs. Only it doesn't chug with the beefiness in Ola's video because he has expensive recording microphones recording the sound. However, with the proper settings, and additional distortion pedal support, it's a great little portable practice amp. It sounds great with my Boss Metal Zone distortion pedal. It's great that you can put batteries in it. But I don't like using batteries because when they start to go bad, they usually slowly negatively impact your sound without you realizing it. I bought the extra power supply cable and love it. (Boss PSA-120S Power Adapter) I make home recordings with a Zoom hand held, open room recording device, with this amp, and the recordings come out great. If you're looking for a great sounding, inexpensive practice amp to travel with, or practice with at home, I highly recommend this little guy. I've been using it regularly for the past 6 months and am a satisfied customer. Thank you BOSS for this fine product, and thank you Ola for helping me decide on this!! Cheers!!

The ideal practice/late night noodling amp
i’m a long time hobbyist guitar player of several decades and I have several nice larger combo amps. I was specifically looking for something that was simple, didn’t have a bunch of presets, app connectivity or other gimmicks on it, something that was just immediate, small, quiet and still sounded halfway decent. Figured I’d give this thing a shot. For the price, you can’t really go wrong even if it’s just OK. Well, it’s better than OK. It sounds surprisingly good and it’s really fun to play! I like that you aren’t overwhelmed with choices. You get gain, volume, EQ and a limited but useful little delay effect to give you Some ambience. All three channels sound great no matter how you set the gain or EQ on the amp. It’s like they really confined the ranges of the controls to keep the thing sounding good. I’m especially surprised at how smooth the distortion is. On old cheap solid state amps of this size, you would usually get a bone-dry clean sound or this really awful, staticky distortion, and nothing in between. The distortion on this actually sounds pleasing and smooth, and it doesn’t do that flubby farty thing when you crank it up like some amp distortion does. Overall, great little amp for late night noodling, taking over to a buddy’s house for a jam without having to lug the larger amp or just having a quick and immediate way to practice without firing up your larger rig. Highly recommend

Excellent Little Portable Amp With Lots Of Uses.
I had been looking at various battery powered amps for a while trying to decide which to get. Since I already have two full size BOSS Katana amps I almost went a different direction but now I'm glad I went with the Katana Mini. For starters it's super lightweight. It's perfect if you want to practice around the house but also to grab and go for singalongs while camping or at BBQs or family gatherings etc. It's also the perfect amp to keep on your bench if you work on guitars like I do. The sound quality lives up to the BOSS Katana name. You get a choice of 3 different amp types for everything from pristine cleans to heavy distortion. While the amp has built in delay with level and time controls I would have preferred Reverb with a couple of different options for type. But that's just me, and the delay the amp provides is excellent. Battery life seems to rip out around 7 hours give or take. I would suggest you get rechargeable batteries and if you use rechargeables rated at 2500 or greater mAh you will get closer to 9 hours on a single charge. Some people have complained that they can hear a low hum or buzz when running on battery. I have not had this experience but YMMV. There is also an input for use with an AC adapter. This, in my personal experience is where some problems come in with noise. Using a third party adapter that was recommended with this amp caused a serious amount of hum both with and without batteries installed. Buying the BOSS PSB-120 at $30 improved things, but there is still some noticable hum even with a guitar with humbucking pickups. That small issue aside, it is a very lightweight grab and go amp with great sound and lots of possible uses. Pro tip: I also have the BOSS Katana GO. I bought a 3.5mm TRS male to 1/4 in. TS male adapter cable here on Amazon and plugged the output of the Katana GO into the input of the Katana Mini. Now I have a full powered Katana amp with all the effects and sound editing possibilities that I can throw in a backpack and take with me anywhere!!!

An excellent practice amp
With realistic expectations most will find this to be an excellent, portable practice amp with really fantastic, fun sounds. It does not sound like your 1x10 or 1x12 combo - it can't. But it produces inspiring, room-filling sounds that defy logic. I didn't want something with a ton of effects, and this only has a delay which can get you a small room reverb, slapback or a longer delay with a few repeats. I prefer reverb, but this works fine to give some ambiance. The EQ works pretty well, but you don't get a huge amount of variance - this will never produce huge bass, but it can give you pleasingly warm, larger-than-expected guitar sounds. You can dial in a substantial variety of tones with the gain knob - clean can get pretty crunchy, and you can get a clean sound out of the crunch channel, etc. The headphone out sounds really good - basically just like the speaker - and an aux in lets you pipe in jam tracks or whatever you want to play along to. I've gotten over 12 hours of life from my first set of batteries - and still going strong, but I play at conversation level. Cranked this gets loud, but about what you'd expect from something this size. You could be heard if you tried to busk with it, but even dimed the volume isn't substantial - but it's plenty loud for what it's intended to be. This is exactly what I wanted - it sounds great and is very portable. I now plug in to practice in places where I used to just play an unplugged electric guitar. It makes practice more fun, and I find I'm practicing more. Without a ton of effects to hide behind I practice better - I can hear when I make a mistake. The Blackstar Fly 3 is cheaper - I don't know if it's better, I don't have any way to compare. I'm very happy with this amp - it does what it was designed to do very well.

The perfect individual practice amp
This amp is literally perfect for someone who wants to practice in a home without disturbing other people in the home. I had been using my main amp with headphones - but began to worry about my hearing, as I tended to listen too loudly. This began my quest for the perfect practice amp... after trying about 5 others, I finally found this jewel. Here’s why I love it: 1. It’s the perfect size and weight. It’s small enough that you can set it pretty much anywhere (your desk, coffee table, on the couch beside you, etc). But it’s heavy and big enough that it does not tip over and it feels like a “real” amp. Although it is quite small. 2. It has the perfect amount of tone control for a practice amp. Gain and master volume with Clean, crunch, and brown settings and with bass, mids, and treble controls. Add to that the delay settings and it’s perfect. Not too many things to waist your time fiddling with - but just enough so you can quickly dial in a perfect and great tone for whatever you are trying to play. 3. It has the perfect volume. Many of the small practice amps still need to be pretty loud to sound good. This little guy sounds awesome at low volume. I can sit in my office (a bed room) And jam heavy tones headphone free, and no one in the house can hear me! 4. It works great with batteries and that makes it very portable. 5. You can use a power supply (not included) when convenient to save battery money. Now for a couple of things to be aware of: 1. It does not come with a power supply, you’ll have to buy one separately (9v 500ma aka .5a with a negative center). I found one on Amazon for 12 bucks. 2. It does come with a set of AA batteries, and I used it all day with just the batteries and they still seam fine. I’m not sure yet how many days they’ll last though... 3. This amp probably could not be used for a full band practice IMO. The sound is just not big enough for that. It if your looking for the perfect individual practice amp at a great price... look no further. This thing is awesome.

Very Good for Small, Ultra-Portable amp, Poor Website for Instruction
Seems well designed, well built and functional... works well for what it is (convenient, ultra-compact, mini-amp). Probably 'best in it's class' and sound is very good at lower volume(s) but don't expect this mini-amp to compete with much larger/heavier 110V powered amp(s) with much more power and larger speaker(s). I am very satisfied with this product and I would repurchase BUT the website is very POOR, difficult to navigate and essentially tells nothing about how to most effectively use/configure this product... it 'hypes' the newer Boss Katana 'x' model with more features... that said, players with even some experience should be able to figure out on their own how to use/configure this product... I would repurchase but don't expect much helpful/info from the website. Now that I have used it for awhile, I love it and it's working great... I really like this amp with my nylon string 'crossover' guitars... it works well with steel strings, but it really sounds great with nylon string instruments.

Great little amp.
Great portable amp. Has a good sound. Easy to take along and fit in small spaces. Would recommend especially as a practice amp. Good value for the price.

Best amp I have seen so far
Bets amp IVE used. Multiple option for gain type. And wall or battery power. Packs a punch, despite its size being about 2 or 3 inches tall. Gain is amazing. Best amp every with electric. Very durable and give you the best without breaking the bank. Sounds very clear with little distortion, despite the gain, and looks sleek in any environment. Easy controls, durable, good value for the price, looks good, sounds good, and is the best

Muy buen mini amplificador
Había visto muy buenas críticas, y tienen razón. Solo lo he probado un poco, pero suena muy bien, tanto a pilas como enchufado (no noto diferencia). Ecualizador de bajos, medios y altos (raro en algo tan pequeño) y tres modos de amplificador. En Crunch y Brown mete ruido, pero nada horrible, lo esperable. El sonido limpio es muy limpio, y parece encajar bien los efectos a través de pedales. Si subes el gain llega a sonar bastante alto para lo pequeño que es. Devolví un Blackstar Fly 3 porque el ruido con su fuente de alimentación era horrible, con este no pasa usando la fuente recomendada de Boss.

Klein und fein
Auch wenn das Gehäuse "nur" aus Kunststoff ist sieht der Amp super aus. Bei der Größe anders aucht kaum machbar. Alles greift sich wertig an und funktioniert. Die Kopfhörerbuchse ist an der Rückseite nicht optimal angebracht aber bei der Größe wahrscheinlich nicht anders machbar. Auf der Oberseite wäre mor die Buchse lieber gewesen. Der Sound ist der größe entsprechend gut. Ich nutze den brown Sound und der kleine macht für den Heimgebrauch ordentlich krach. Mit Kopfhörern ist er mir zu leise. Netzteil leider nicht inklusive. Aber durch Batteriebetrieb flexibel für Unterwegs und wahrscheinlich hat jeder Musiker ein 9V Netzteil irgendwo rum liegen. Aber das sind nur meine Empfindungen. Darum gebe ich trotzdem volle Punktzahl.

Fantastiskt ljud i litet format
Utmärkt tränings-förstärkare. Mycket fint rent ljud men bra overdrive om det är det du är ute efter. Plus för inbyggt eko.
