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.

A loud amp at a great price
Product Rating
What is your opinion of this product?
Overall it's a great amp. I don't really like the reverb on this amp. It seems too aggressive even when turned down. Then again I don't use effects very much. As I play mostly rhythm guitar. The Crunch setting is what I use the most. It models that 70s hard rock sound extremely well.

Best bang for the buck
What is your opinion of this product?
I am very happy with this purchase. At this price range, this amp really delivers. It is oddly warm for a non-tube amp. Overall best practice amp I’ve ever had.

Best amp at its price range (by far)
What is your opinion of this product?
This amp is by far the best beginner amp available, the best amp for home practice, and the best amp, period, at this price range. Not only is it the best sounding solid state amp, it also comes with access to about 50 Boss pedal effects theough the Tone Center app. It has everything you need to practice at home (and even to use at small gigs.) There is no way you will regret buying this amp.

Very nice
What is your opinion of this product?
I wish I had this back in 1999. Great tones and sound versatility. Only thing the amp needs is blue tooth and you wouldnt need any other practice amp.

Very good amplifier for the price.
What is your opinion of this product?
For around $200 you get a very good amplifier and effects that do a very wide range of things that would otherwise cost you an arm and a leg. Having the ability to switch to.5 watts output is one of the main reasons I chose this amplifier over the Marshall Code 50. I have not been disappointed. This amp performs perfectly in every situation I have used it in.
