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.

Great Amp
What is your opinion of this product?
I bought this to use as a practice amp and it works wonderfully for that. Great tones for a solid state amp. Tons of effects options that can be changed through the software. Easy and super simple to use. I've played a couple smaller gigs with this amp on occasion when my tube amp was overkill. By small -- basically a school gym. The 50 watt will get fairly loud in an enclosed space. Great, great practice amp though.

Wow! It’s all true!!
What is your opinion of this product?
I’ve research this amp along with it others in same catergory and above, all the reviews where so compelling towards the Boss katana, it seemed that no matter which Boss Katana I would pick I would whip in a good place. So I did, and I’ve been so happy and so impressed!!! For the price, I cannot believe the sound quality and the options. It definitely lives up to the hype, I would recommend the Boss Katana! I cannot wait to try the Boss Next amp, and of course with American Musical supply and the easy options to buy i will!! I love it, and I love this companies.

Best features for the money
What is your opinion of this product?
I'm a pro musician who's college-age son wanted a "real" amp of his own. After comparing Fender, Marshall, Orange and a few others, I thought the Boss was the best "bang fort the buck" and as of Christmas morning, our son thinks so too!

Better than I expected.
What is your opinion of this product?
Awesome little amp, I couldn't believe the tone and options. It really comes to life after you hook up to the boss tone studio on your computer. I highly recommend anyone from beginner to pro.

Awesome Amp And Value
What is your opinion of this product?
I have only had the amp a week and I have not had a chance to play it much but when I have played it I really like it a lot. This amp was an upgrade from my Acoustic 20 watt amp . I think I will be keeping this amp forever. I have had a few Peavey's the bandit and vyper series but I feel like this Boss amp will be the boss. I have a friend who can't wait to see it and hear it and I'm sure he will buy one. The only complaint is no foot switch included but I think you can buy one from $30 to $60. Boss has 2 or 3 year warranty on the amps plus one year free extended from ams. Just buy one today!

Whoa is this thing LOUD!
What is your opinion of this product?
Whew! Tones are killer. LOUDEST 50w amp in existence. I don’t think I’ve even had to turn it to 50w yet actually. Being able to select the watt output is a nice feature. The manual could be more in depth, but it’s easy enough to figure out just messing with it for about 15 mins. Killer amp. Would buy again!
