BOSS Katana-50 MkII
BOSS Katana-50 MkII

THE EVOLUTION OF A MODERN CLASSIC

Katana MkII takes the acclaimed Katana guitar amp series to the next level, turbocharging the core platform with more sounds, more effects, and more features. Newly voiced variations are now available for all five amp characters, doubling the tonal options. And the onboard effects categories have been expanded from three to five, providing even more real-time processing to choose from. The usability has been ramped up too, with a power amp input for modelers and multi-FX, updated editor software, and many other enhancements.

Stage-ready 50-watt combo amp

  • Custom 12-inch speaker
  • Class-defying power, punch & cut-through
  • Five unique amp characters, plus newly voiced variations for each
  • Five independent effects sections, each with three variations
  • Dedicated Pedal FX
  • BOSS Tone Studio software for customizing your sound
  • Cranked-amp tone and response at low volumes
  • Mic'd cabinet emulation

More Sounds, More Versatility

The stage-class Katana MkII lineup picks up where the first generation left off, building on the same core tones and features that have made the series such a worldwide smash. If you loved the original Katana amps, you'll love Katana MkII even more. And if you're new to the party, get ready for sound, feel, and versatility that soars far beyond its class.

Five Amp Characters, Ten Overall Tones

Katana MkII's five primary amp characters offer everything from organic vintage tones to modern high-gain sounds, plus a dedicated voice optimized for acoustic-electric guitar. The characters have now been extended with newly voiced variations, providing a wider palette of tone options to craft your personal sound.

Five Effects At Once

Katana MkII now includes five simultaneous effects categories, putting the tone-shaping power of a massive pedalboard right inside your amp. Independent Booster, Mod, FX, Delay, and Reverb sections come loaded from the factory with three variations in each, providing 15 ready-to-play effects to choose from. Connecting to BOSS Tone Studio lets you dive much deeper if you want—customize the sections with over 60 different effect types, change the order with four different chains, and much more.

Full-Throttle Sound Every Time You Plug In

Backed by BOSS's Tube Logic approach, Katana MkII delivers the authentic output distortion characteristics of genuine tube amplifiers, with the sound and feel becoming richer and more responsive as you turn up the volume. But unlike that classic tube amp, Katana MkII's variable Power Control makes it easy to fly in the sweet spot without getting fired from the gig or kicked out of the house. Just throttle back the overall volume as needed to enjoy inspiring, cranked-amp sound anywhere you play, from bedroom to stage.

Amplify Your External Gear

The Katana-50 MkII rocks as a standalone amp, but it also excels as a powered cabinet for a favorite preamp, modeler, or multi-effects unit. Connecting to the rear-panel Power Amp In jack bypasses Katana MkII's preamp and effects, letting you tap straight into the Tube Logic power section, complete with grab-and-go Power Control. And with BOSS Tone Studio, the input can be easily optimized for your particular gear with a high-pass filter and adjustable gain.

One-Touch Recall Of Custom Setups

One of the Katana-50 MkII's most powerful features is the ability to store favorite amp character and effects setups in Tone Setting memories for instant recall. After you've dialed in a sound with the panel controls, simply save it to the desired memory with a quick button hold. Four Tone Settings (two banks of two) are available, with fast selection right from the panel. It's also possible to connect external footswitches for hands-free control on the gig.

Ready-To-Mix Direct Tones

The Katana-50 MkII features USB and phones/recording outputs with mic'd cabinet emulation, letting you send mix-ready amp tones to a computer DAW or headphones. The direct sound can be shaped with three different Air Feel settings, which are accessible from BOSS Tone Studio. Two-channel USB operation is supported, allowing you to track in true stereo with many of Katana's modulation, EQ, delay, and reverb effects.

BOSS Tone Studio Enhancements

BOSS Tone Studio has also evolved alongside the Katana MkII amplifiers. The interface has been updated with a refreshed look, and a number of parameters have been consolidated into the main screen for faster workflow. There's also a dedicated Pedal FX category, making it easier to assign wah and pedal bend effects to a connected expression pedal. And if you're a first-gen Katana owner, it's possible to import your custom patches and use them all with Katana MkII.

    Customers like the sound quality of the musical instrument amplifier. They mention that the sound is amazing, it's plenty loud to use on stage, and is great for low to higher volume use up to gigging. They also like the 12" speaker, which is hard to find in a low power practice amp. The amp is perfectly quiet even at maximum volume, and works excellent with almost any audio or midi program on computer. It has many different tone options and the capability to store/save your presets, and produces consistently great output all the way from conversation level to cops-at-the-door.

    5.0 out of 5 stars Truly an Amazing Guitar Amplifier
    Reviewed in Canada on January 11, 2021
    This is really an amazing amplifier.

    Do not let the smaller size fool you as it is very powerful and loud enough to play a small gig. I have never had the volume higher than 11 and that is as loud as I dared.

    I did hours and hours of research on line before I pulled the trigger on this amp. Originally I was hell bent on buying a Tube amp. Well the one that I was looking at buying only had one channel and I wanted a 2 channel amp for more versatility.

    After seeing many YouTube videos on this amp with an expert saying that it is difficult for him to tell the difference between this amp or a tube amp made me get off the Tube amp train.

    The fact that this amp not only has one channel but 4 channels was for me the final selling point along with the great sound. With the foot switch that I bought I can easily switch to any of the 4 channels in a heartbeat and as such no need to buy a lot of guitar pedals to get various effects.

    One can set the Wattage to 50, 25 or even a 0.05 Watt and even at that low setting there is still lots of Volume.

    Fun Fact

    Something you may never read or see but this amp uses 8.5 Watts of power and that is whether it is on the 50 Watt or 0.05 Watt setting. So this amp is easy on your Hydro bill. My hair dryer for example uses 1365 Watts.

    The amp comes with many built in sound effects. If you download for free the Boss Tone Studio software one will almost have an endless amount of effects as each one can be tweaked and then saved as a patch for future use or saved direct to the amp.

    One can also buy patches crated by others that have a special sound that you may like, Also lots of free patches. For more info on how to use the software and even the Amp, check YouTube as many good videos on there.

    For the price this amplifier sure is hard to beat and made in Japan is a plus as we know that Japanese Products are top quality whether it is cars, snow blowers, small engines etc. Huge difference between made in China or made in Japan . The shipping was also fast.

    If you are looking for a great amp with a super price tag, you have just found it.

    La verdad es que no sabía que amplificador comprar, ya que estaba buscando un sonido bastante limpio, después de ver varias reseñas me animé a comprarlo y la verdad es que no me arrepiento de la compra, es un buen amplificador, en lo personal siento que te estás llevando más, por el precio tan bajo que tienen los boss katana, en cuestión de volumen con poner la perilla del atenuador de potencia a 25w ya sube bastante la salida de audio, lo mejor de todo es que puedes usar varios pedales de boss desde el programa boss tone studio, aparte puedes editarlos bastante bien, yo he usado pedales análogos con los efectos digitales que trae incluidos el amplificador y la verdad es que es demasiado bueno
