    Product Description

    With crafted tones, the Katana 100 is an inspiring rock amp born of Waza DNA. The Katana series presents guitar amplifiers with smooth, cutting tones honed by generations of dedication and expertise. Katana—the traditional sword carried by the historic samurai of Japan—is a symbol of honor, precision, and artistry in Japanese culture which is why these amps carry the majestic sword’s name with pride.

    Boss Katana 100 Guitar Amplifier Features

    • Stage-ready 100-watt combo amp with a custom 12-inch speaker
    • Five unique amp characters: Clean, Crunch, Lead, Brown (derived from the Waza amp), and Acoustic (for acoustic-electric guitars)
    • Choose from 55 customizable effects with Boss Tone Studio editor software
    • Store 15 different effects on board, with three effects available simultaneously
    • Dedicated gain, EQ, presence, and effects controls for adjusting sounds quickly
    • Four memories for storing and recalling all amp and effect settings
    • Power Control for achieving cranked-amp tone and dynamic response at low volumes
    • Built-in tilt stand for optimal monitoring and sound projection
    • Pro setups available at Boss Tone Central 
    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 100 watts of power and a custom 12-inch speaker, the Katana-100 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-100 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.

    A Refined Amp with Inspiring Tone
    Designed for guitarists who are serious about their sound, the Katana-100 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-100 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-100’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-100 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. Four 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-100 includes many advanced features, it’s amazingly simple to operate. Dedicated knobs for multiple gain stages, three-band EQ, and presence 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 amplifier!
    What is your opinion of this product?
    I think this amplifier is worth the money and it is very usable live. I am almost 60 and have been playing guitar over 60 years. I have had most popular tube amps since the 60s (Fender Marshall Supro) and still have most of them. I play a strat or something loaded with P90s for a little more ooomph. I purchased this amplifier from AMS along with the GAFC. I have the latest firmware loaded into the amp. I spent a week of evenings tweaking it with the software and did a factory reset.....that is good enough for me. The GAFC is not needed for how I play. Lead setting, gain 11 o'clock (oc), volume full, bass 3oc, mid 12oc, treble 11oc, add reverb to taste, presence 9oc, adjust master for level. Use volume knob on guitar to roll of gain and adjust picking heaviness to clean it up. It is a usable gig-able amp. Side by side with a tube amp? No. Who cares? It sounds great. Keeper? I don't know. I have GT1 direct.

    Well worth the money
    What is your opinion of this product?
    After several weeks of research and testing this amp seemed to have widest range and programmable effects

    What is your opinion of this product?
    Reacts like a tube amp without the weight. Can handle any size venue. You can retire your pedal board as well. Best investment I could have made!!

    Best Amp for the Money!
    What is your opinion of this product?
    This is a beast. You aren't going to realize what this amp can do if you don't connect it to the free software, but its really quite easy. You get very tube like response from this thing and all the variable drives/effects you have access to are great. Oh, and volume for days. This definitely packs a punch. Unless you just refuse to use the software, there isn't a better amp for the money. Even just throwing some of your own pedals in front of the clean channel on this is enough to beat most amps in the price range.

    We'll see
    What is your opinion of this product?
    Well I had the 50 watt, and liked it, but had some problems. I have always been a tube guy, but I read a lot of reviews and figured I'd try the 100 watt. So far it really is the best solid state amp I've heard. I wish it came with a footswitch, but I really don't have any negative comments yet. I love the fact it's so light and the kick stand is a great idea.

    A No-Brainer
    What is your opinion of this product?
    1X12,4 channels, 5 amps,55 Boss pedals, power attenuation. Not to mention it sounds and feels great. A very dynamic amp. But you've heard all this before. Still on the fence? Well, don't be.

    Just not sure real yet.......
    What is your opinion of this product?
    I've always believed in first impressions and I've oftenn been surprised when my first negative impression of something became quickly overshadowed by a cascade of positive impressions. I've read all the reviews for this thing and watched every video online before pulling the trigger on the purchase. It arrived yesterday and I have to say that underwhelmed has a new benchmark. I found all of the default settings harsh and shrill all except for the acoustic channel which was exceptional when I used a Taylor GS-Mini with just a touch of delay. Absolutely stunning. The regular clean channel was lackluster. The other channels sounded about as bad as a solid state amp can sound except the Brown channel with some delay and compression. I haven't owned an SS amp since 1981. I had assumed that perhaps the technology had improved in the last three decades. I used a new 335, a 78 LP with PAF's, a Strat with Texas Specials and a guitar I built at luthier school with some P90's. No joy.....
