What we say:

At A Glance:

BOSS Katana 50W MKII 1x12 Combo is a feature-packed amp that'll win the heart of any player. With a huge selection of modelled amps and FX built-in, it's easy to find and tweak the selection of tones you're looking for, plus with 50 watts of power, it's loud enough to have you covered at any gig.

Whether you're a professional, casual player or complete beginner, you're going to love the Katana 50W MKII!

Features We Love:

Who the amp is for

As an all in one amp, the Katana 50W suits virtually any player, from jazz and blues, to rock and metal, the Katana does it all, it even caters to acoustic musicians. With a huge selection of quality amp sims and FX built-in, it's easy to create a selection of sounds for your full set, or even for use in different bands, this also makes the Katana a great tool for experimenting with and honing your own sound.

A key part behind the Katana's genius is its plug and play nature, all you need is a guitar, a cable and the Katana and you're good to go for virtually any gig or session. Plus, its 50 watts of power is loud enough for any gig, but it doesn't need to be cranked to feel lively, which will please your band mates and also makes the Katana ideal for practice at home. It's also fairly compact, meaning it's easy to travel with to gigs.

All of the above makes the Katana an ideal option for any player, it's got the features to please experienced players, yet it's affordable for the beginner to invest in and will grow with you as you develop.

Amplifier section

Boss have pioneered amp emulation technology for decades and inside the Katana you will find realistic amp sims that sound great and react naturally to your playing.

Multi-FX engine

Katana is host to over 60 different effects types, with the ability to run 5 effects at once in any order, the Katana is like having a huge pedalboard with you at all times.

Boss Tone Studio software.

The free Boss Tone Studio software is like a gateway inside the Katana. You'll love using the software to create custom patches with complicated FX chains and execute in-depth tweaking.

Audio interface with Re-Amping

The Katana can also work as an audio interface, recording over USB into your favourite DAW. Not only are you able to record your amp sounds straight into the DAW, it's also possible to record your dry signal and effectively "re-amp" your guitar using the Katana and refining your tone to perfectly fit in your mix.


  • All the amp sounds and FX you'll ever need
  • 50 Watts is more than enough power for gigging
  • Record directly to your computer

Christine M. - 29/12/2020

Erkut E. - 29/12/2020

Can't believe how much "stuff" is crammed into this superb sounding amp . . . and for such a great price.

Jim G. - 26/12/2020

Amazing little amp, such an array of sounds straight out of the box and using the software gives you another level of choice and modeling altogether. A very worthy purchase would even consider the 100W as a gigging unit with this versatility.

Richard H. - 26/12/2020

compact amp for the home; well suited to the guitar and size of room.

Loftus B. - 18/12/2020

Brilliant amp for beginners like me. It has all sorts of effects to keep me entertained for hours and hours.

Alex S. - 9/12/2020

Great mid-range amp with a lot of features (effects, distortion/overdrive etc) and a powerful sound

Geffen L. - 7/12/2020

Tracy C. - 2/12/2020

Boss katana amps are awesome and offer such a wide range of tones and effects. As a middle aged beginner, I have just started to purchase a few pedals so the on-board fx in the katana are extremely handy as I build up my pedal board. I also like the fact that you can physically adjust the knobs without having to use apps etc.

gilbert w. - 2/12/2020

Christopher P. - 2/12/2020

Excellent sound quality and fantastic effects

Susan W. - 21/11/2020

Good tones straight out the box

Kenny S. - 12/11/2020

peter r. - 10/11/2020

Believe the reviews. This is the only and last amp you'll ever need.

Steven F. - 9/11/2020

David P. - 8/11/2020

Bought the Katana to upgrade my Fender champ 20. Absolutely fantastic amp. Really opened up the tonal qualities of my guitars. Always wanted an LP Standard but Gibson is out of my price range so went for the Epiphone and it's fantastic! Build quality, fit and finish are excellent for the price! It fits nicely along with my Player Strat and it rocks!

PETER W. - 25/10/2020

John B. - 25/10/2020

Great shop. Very knowledgeable, helpful people!

Keith D. - 17/10/2020

That 0.5 watt setting is ideal for a household and teaching setup

Dale F. - 15/10/2020

Exactly what my son needed.

Dorothy B. - 6/10/2020

This little amp has everything you need for practicing, or gigging on a budget. Loads of boss effects loaded in. Great value for money. I have had nothing but fun with this since I purchased it from Guitar Guitar. Would highly recommend.

Brian M. - 6/10/2020

Luke S. - 5/10/2020

Great all round amplifier. Amazing tones for all types music. Plug in and play straight out the box and has a tone of tones and pedals on the boss tone studio. This amplifier can get loud so the 0.5w and the 25w setting comes in handy for bedroom practice.

Ross T. - 18/9/2020

Amazing sound and absolutely ideal for a home setup. Best amp to use at home I'd say.

Steven N. - 15/9/2020

Scott M. - 7/9/2020

Really enjoying this product.

David B. - 27/8/2020

sian b. - 26/8/2020

Amp has plenty of effects and sounds really good. The PC application that works with the amp is amazing. I would recommend for all playing styles except modern heavy metal guitar as the heavier high gain sounds are a bit lacking IMHO.

Matthew B. - 25/8/2020

Eric F. - 22/8/2020

I haven?t worked out all the settings yet but I?m pretty sure it will then prove to be a five star product. At the moment it?s probably too much amp for my electric guitar capabilities.

John S. - 14/8/2020

Margaret F. - 17/6/2020

It is just what i needed for home practice and party time. just bursting with different settings.Brill.

Anthony G. - 5/6/2020

Great little amp with lots of features.

Great guitar amp, very versatile as it works with electro-acoustic guitar. Lots of features, highly recommend

Alain L. - 3/6/2020

Very easy to use. Some excellent tones to be found in this amp. The power dial is a welcome feature if you've got sensitive neighbours.

Ian F. - 3/6/2020

Alex E. - 1/6/2020

Fraser L. - 29/5/2020

Huw L. - 26/5/2020

Great value for manoey. Can't go wrong with the Katana 50

Michael L. - 24/5/2020

Ideal amp for home and home studio work.

Ian M. - 23/5/2020

The amp itself is top class. I?m surprised it?s not more expensive. The sound is great through the 12inch speaker and really user friendly. Could not recommend more. Everyone should face one.

Thomas . - 23/5/2020

Katana is a great mix between simplicity and complexity - however you want it - plays great out of the box, but if you want to get into detail via USB connection to a PC you can. The standard tones / variations are well voiced, and a i love the line in to hook my Helix direct to the power amp section if I am using IR's or cab simulations.

Chad M. - 23/5/2020

Sounds amazing compared to my old Marshall amp and has loads of tones and effects To play with.

Barrie T. - 22/5/2020

Ryan N. - 21/5/2020

Unlimited possibilities. Quality sounds.

Matthew B. - 29/4/2020

Can?t go wrong with this amp buy one.

Graham K. - 28/4/2020

The Boss Katana 50 Mkll is a first class amplifier. Comparatively light weight as well so, no more threats of a hernia - hopefully.

Tad K. - 28/4/2020

This amp is fantastic, really impressed!
