Product Description

With 50 watts of power and a custom 12-inch speaker, the Katana-50 delivers a commanding range of gig-worthy tones that gracefully slice through any band scenario.

Katana Version 3:
Added Effect Types, New Real-Time Control Assignments, and Stereo Effects When Recording via USB

The Katana Version 3 update enhances the stage-class Katana amp lineup with even more performance versatility. New effect types include the legendary Roland DC-30 Analog Chorus-Echo, classic BOSS GE-10 Graphic Equalizer, and expressive 95E pedal wah, providing iconic tones that perfectly match the Katana’s Brown amp character. In addition, BOSS Tone Studio offers the ability to assign favorite parameters for quick-access control from the front-panel effects knobs and create custom control assignments for up to three connected expression pedals. And when tracking in a DAW via USB, it’s now possible to capture true stereo sound with many of the Katana’s modulation, EQ, delay, and reverb effects.

Katana Version 3 is a free, user-installable update for all Katana owners.


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.

Crafted Tones, Forged for Rock
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.

Inspiring rock amp born of Waza DNA.

A Refined Amp with Inspiring Tone
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-inch 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.

Five Original Amp Characters, Honed for Rock Playing
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.

Leave Your Pedalboard at Home
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.

Grab-and-Go Operation
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.

Boss Tone Central
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.

Versatile Value

Product Review

They say you get what you pay for, however with the Boss Katana KTN50 you get a whole lot more. This product provides you with a plethora of tonal possibilities in a compact package and the power to make yourself heard. Right out of the box this amp sounds good, but as you become familiar with the features this amp sounds great. The 5 amp types provide the user with a solid starting base to create your tone and by using the amps equalizer and effects controls allows the user to fine tune. The Boss effects, included in the amp, don't disappoint and can be changed or customized via USB interface with your computer and downloading the program listed in the manual. The manual is easy to understand and explains all the product features in a to the point manner. The bottom line is this amp will meet the needs of the beginner and advanced guitarist without breaking your bank or your back. I would recommend purchasing the optional footswitch to allow switching from channel "A" to channel "B" for increased versatility, but other than that, plug in and start jamming.

Lightweight but packed full of features!

Product Review

Just had back surgery. Was carrying a tube head, 2x12 cab, and large pedalboard. I am now carrying a 25 lb amp and small pedalboard. Crazy thing is how great it sounds and how much control you have using tone studio. Add the FS6 and I have four presets on the fly. Thanks Roland!

Best Bang for Your Buck

Product Review

Not only is this amp light and loud, it's fun. This would be a great amp for a beginner or intermediate player that isn't ready to invest in a lot of pedals. Because it has so many different tone options just to play around with you can find the sound you like best before taking the next step up. I'm still noodling with it, but I like it, I like it a lot.

I LOVE THIS AMP!!!

Product Review

This is the ONLY solid state amplifier that I own and IT IS AWESOME! I own a lot of old boss effects pedals and with this amp I don’t need them. With the usb connection to pc and boss tone central this amp can emulate ANY tone. With the “acoustic “ channel I play my acoustic guitars and it just sounds great. Really digging the attenuation control as well. Almost sounds 100% tube driven. Lightweight, loud and feature packed. Way to go boss!
