Katana Gen 3: Inspiration Unbound

Backed by our advanced Tube Logic amplifier architecture and reactive Class AB power, the BOSS Katana series has become a standard for guitarists everywhere since its introduction in 2016. Katana amps embody decades of BOSS development knowledge, providing professional, tube-inspired sound coupled with modern advantages like onboard effects, one-touch memory recall, deep sound customization, and reduced weight. Katana Gen 3 elevates the lineup with even more range and versatility, bringing you a playing experience that goes where no other amps can. 

Refined Tube Logic Tones

Tube Logic recreates tube circuitry and all its complex interactions at a component level, putting the coveted tone and feel of classic tube amp designs under your fingers. Our approach continues to evolve with refinements to the five amp characters available in previous Katana models, including the iconic high-gain Brown type. The new Pushed character spotlights internal dynamic enhancements with the pleasing touch-responsive gain of a clean combo driven into harmonic saturation. All six amp characters include a selectable variation, giving you 12 distinctive tones to support every musical style. 

“Sweet Spot” Sound at Any Volume

As every tube amp lover knows, the sound becomes richer, fuller, and more responsive as you turn up the volume. Unfortunately, it also gets way too loud for many playing situations. An external power attenuator is a common solution, but it can introduce artifacts that color the amp’s tone and feel. The integrated Power Control in Katana Gen 3 delivers the best of all worlds, letting you dial in cranked-amp inspiration with no adverse effect on the sound. Just turn the panel knob to transparently harness the level for everything from live stage playing to daily bedroom jams.

Famous BOSS Effects

Katana Gen 3 features five simultaneous effect categories loaded with essential selections from the historic BOSS library. Booster, Mod, FX, Delay, and Reverb sections offer enhanced sound quality, grab-and-go parameter controls, and three variations each for access to 15 unique effects. BOSS Tone Studio unlocks additional possibilities, allowing you to customize the onboard effects from 60 different types and tweak deep options not available from the amp’s panel. And when the optional Bluetooth Audio MIDI Dual Adaptor is installed, you can wirelessly edit sounds on the gig using the BTS editor app on your smartphone.

Unrivaled Sound Shaping

BOSS Tone Studio for Katana Gen 3 offers new visual enhancements and graphic customization options that make crafting your tone faster and more intuitive. Explore amp and effect editing tools, change the effect order, and shape the overall sound with the three-way Contour control and multiple EQs. Dial in system-wide settings and behaviors. And organize custom setups for all your gigs. You also have access to BOSS Tone Exchange, where you can download pro setups and share sounds with the worldwide Katana community.

Complete Stage Command

Katana-100 Gen 3 features a host of powerful tools for modern performers. Eight Tone Setting memories let you store and recall complete amp/effect setups, while rear-panel jacks support remote control with footswitches and an expression pedal. The GA-FC and GA-FC EX Foot Controllers extend your capabilities even further, providing complete stage control solutions for your Katana Gen 3. Switch Tone Settings, turn effects on/off, integrate multiple expression pedals, and more. The GA-FC EX model also includes an expansion option to double your footswitches or control two Katana amps at once.  

Expand Your Range

Katana-100 Gen 3 flows with all your creative journeys. Easily link two amps via the Stereo Expand* function, with master control from the main amp and stereo effects like chorus, delay, and reverb distributed across both amps for a wide, immersive sound. Or connect to the Power Amp In jack to bypass the Katana preamp and use the reactive Class AB power section to amplify a modeler or an external preamp.

*Stereo Expand is supported on all Katana Gen 3 and MkII models except the Katana-50 Gen 3 and Katana-50 MkII.

Get Connected

Katana-100 Gen 3 includes connectivity to meet every need. Plug in headphones to practice quietly with stereo sound. Send a feed to a house PA via the Line Out jack. And record to your favorite music software on computers and mobile devices over USB-C. All audio outputs feature IR-based cabinet sound for great direct tone, with three Air Feel types and two customizable settings in BOSS Tone Studio.

Works as described
Color: Black
Love this whisk. I have arthritis and this is light weight enough for me to use. I love the push button, and the stand for it. It’s really easy to clean, and it blends my shakes nicely without leaving the powder behind.

Very Powerful Frother!!
Color: White
I’ve been using a frother daily for my drinks, and this one really impressed me with its power for such a compact size. It blends heavier powders into smooth, clump-free mixtures in seconds. I’m a big fan of the build—the metal whisk gives it a solid feel, and it comes with a stand to keep it neat on the counter instead of being shoved in a drawer. Cleaning is a breeze, just a quick rinse, and the rechargeable battery lasts much longer than I anticipated between charges. Just a little tip: start in a taller cup and don’t fill it all the way to the top, as this thing can create a serious vortex if you’re not careful. Overall, it’s been a super handy little tool, and I’m so glad I bought it.

Putting my $.02 into the mix
Size: Basic Frother, Color: Black
My old, lame hand mixer finally gave up the ghost. I ordered one of those “stick blenders” but it was waaaay too powerful for my purposes. (I don’t need it to dice/chop/pulverize fruits or veggies - if you need that, this mixer isn’t for you.) I needed something in between. I kept coming back to the “milk frothers,” but I had my doubts that one of those could mix up my morning shake. I tried a frother some years ago, and it wasn’t designed for blending ingredients, just for frothing liquids. Still, I had an idea (like some of you might) that what I needed was not a true stick mixer, nor a true milk frother. Something in between. I needed a “frother on steroids.” I settled on this one-the YUSWKO YW-218. It had the regular frothing head, but also two other heads. One looks like a mini bread hook; the other like a mini whisk. I plugged it into charge and it did take the stated time to come to a full charge. (Like any kid with a new toy, I tried turning it on before charging, but the low state of charge resulted in the high-medium-low settings not behaving correctly.) For my first few forays into blending, I tried the mini bread hook thingee. It worked OK, but not as well nor as quickly as I wanted. I then shifted to the mini whisk thingee. I didn’t really prepare well. I combined my milk-protein powder-carnation breakfast-malt flavoring-imitation (yeah, I know, it probably causes cancer, but only in California) vanilla flavoring concoction into my normal medium-sized concession cup (you know, the smaller ones you get at high school basketball games), lowered the whisk head into the goop, and turned it to “low.” In a second, I was wearing my shake. But the power capacity was more than enough to do what I was needing. Anyway, since that first attempt with the whisk head, I’ve gotten the routine down. And it is EXACTLY what I needed. (I’ll try to attach a video to show you.). Clean up is simple. You can do it with soapy water and a brush or rag, but I just run the thing in clear water and ensure I get all the sticky stuff off. I tried the soapy water, but I got a LOT of suds. A few pointers. First, charge it up all the way before using it. I haven’t had to recharge for two weeks now. You’ll use a regular, small phone-charging brick. (Two words of CAUTION. I found that the included, cheap charging cord did not work. It got really hot, like there was an electrical short in it. So I found one of my own. Also, DO NOT USE the larger charging blocks like the ones from Ap*le. I tried and it was too much.) Second, I assumed that the low speed would be the less aggressive and thus the less “throw-stuff-out-of-the-cup” setting. But that hasn’t proven true for me. I’ve found that the medium setting makes my ingredients behave better (less throw-out and quicker blending). Experiment with different speeds, even though it may not make immediate sense. Third, practice with plain water first (I’ve already told you how I know this). That’ll give you a “feel” for what this frother will do. Fourth, practice with different sized cups. I’ve since changed to the taller concession cups, as they prevent throw-out. Fifth, start practicing with your cups down in a sink. Less mess to clean up and no need to change clothes before you head out to work or school (I’m a teacher). Finally, familiarize yourself with the way the three buttons work. My previous mixer required me to keep the button depressed to blend. If I let up on the button, the unit would stop. Not so with this one. A light press to start, let go, then a light press to stop. Don’t keep mashing the button. Final thoughts: this frother is just what I needed. If your experience sounds like mine, I think this one’ll give you good service.

Perfect and convenient tool
Size: Basic Frother, Color: Black
I am very happy with my new milk frother. Really easy to use and I was very pleased with the results. I got to enjoy my first home made cappuccino and it was perfect. I have only used the frother attachment so far but I plan to use the whip the next time I scramble a couple of eggs. Very please with my purchase.
