Katana—the traditional sword carried by the historic samurai of Japan—is a symbol of honor, precision, and artistry in Japanese culture. Adopting the majestic sword’s name with pride, the Katana series presents guitar amplifiers with smooth, cutting tones honed by generations of dedication and expertise. Born of the development process behind the acclaimed Waza amplifier, these innovative amps embody BOSS’s determined pursuit of the ultimate rock sound. Featuring proprietary circuit designs and meticulous tuning, the Katana series combines traditional craftsmanship and breakthrough functions to produce true next-generation rock amplifiers.
With 50 watts of power and a custom 12" speaker, the Katana-50 delivers a commanding range of gig-worthy tones that gracefully slice through any band scenario. The amp also excels for home playing, with a uniquely efficient design and innovative Power Control that provides inspiring sound and response at low volumes. In addition, the Katana-50 includes integrated access to 55 BOSS effects, which are customizable using the free BOSS Tone Studio editor software. Up to 15 different effects can be configured in the amp at one time, enabling you to bring fully prepared tones to the stage in one amp.
Designed for guitarists who are serious about their sound, the Katana-50 offers exceptional tone and touch response for stage playing, recording and simply practicing at home. The custom 12” speaker is driven by a special method developed for the flagship Waza amp that optimizes the speaker and cabinet character. This gives you authoritative punch and cutting presence previously attainable only with high-end amp designs. In combination with the five selectable amp characters, the Katana-50 produces class-defying power and expressiveness to meet any playing situation.
Sharpened to perfection by the BOSS engineering team, the Katana-50’s five amp characters offer everything from organic vintage tones to modern high-gain sounds. Clean is natural and transparent, while Crunch offers satisfying grit and response. Lead has a wide gain range to suit many styles, from fat, stinging blues solos to fluid legato shredding. With DNA inherited from the Waza amp, Brown delivers refined high-gain tone sought after by the world’s greatest rock players. The Acoustic character further enhances the Katana’s versatility, providing optimized tone that makes acoustic-electric guitars sound stunningly natural.
With its built-in BOSS effects and recallable Tone Settings, the Katana-50 lets you perform anywhere with just a guitar and amp. Connecting to BOSS Tone Studio via USB provides access to 55 effects that are fully customizable for your needs. Going beyond standard distortion, delay, and reverb, the selection also includes powerful tone-shapers like pitch shifting, ring mod, slicer, and more. You can load 15 different effects in the amp at one time and use up to three simultaneously. Two tone Settings let you store custom amp and effects setups for instant recall, and you can always jump to the current panel settings at the touch of a button. It’s also possible to connect optional footswitches and expression pedals for hands-free control on the gig.
While the Katana-50 includes many advanced features, it’s amazingly simple to operate. Dedicated knobs for multiple gain stages and three-band EQ allow you to quickly dial in your tone by ear, just as you would with a standard tube amp. Essential effects parameters are adjusted with a simple knob twist, and memories can be stored with a brief button hold. The Power Control is great for throttling back the volume for small stages and home playing, and also includes a Standby setting that mutes the sound for switching guitars or taking breaks. And by flipping out the integrated tilt stand, you can easily angle the amp back for better sound projection.
At the BOSS Tone Central website you’ll find numerous free amp and effects setups for the Katana series. Created by pro guitarists, these setups provide ready-to-play sounds for various music styles, and also make great starting points for building your own sounds. They load into the memories in a Katana amp via the BOSS Tone Studio editor software, which is also available at the site. In addition to Katana effects selection and customization, BOSS Tone Studio gives you a convenient way to organize all your Katana setups for different gigs, recordings, and practice sessions.
The main features of the Boss KTN-50 Katana 50 Guitar Combo Amplifier include:
Bought this amp for playing rock, blues and jazz. It's great for all of the genres mentioned. The effects sound great, specially the delay and drive (blues driver), reverb is good too.
Bought the footswitch with it and it's easy to switch channels now on the fly.
Can get A LOT of gain out of this little thing. It's easily loud enough for band practice at about 12 oclock at 50W setting, so there's headroom for more. It kept its own versus a 30W tube fender amp no problem.
Shipping was fast and came in perfect condition, well packaged.
I would buy it again if it were stolen.
From the moment that you turn on the Boss Katana 50, you know that you have found something special; a steady- state amp with the depth and tone a tube amp.
With its range of tones and amp models; computer interface; and plethora of programable effects, this is a great practise amp for every player, in any genre.
Very happy with this. Has a great sound and plenty of grunt for a little amp. Amazed that they have found room for a 12” speaker. The only issue is that there is no tuner included. I have seen on the tube that you can go into the programming to enable a tuner, but this is a real pain. Why would this great amp not include a tuner, if it has the capability to. Would add value to this nice piece of kit.
