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.

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.

Katana Version 2: Expanded Effects, More Tone Settings, and Increased Performance Versatility
Available starting in October 2017, the feature-packed Katana Version 2 update adds many user-requested additions and enhancements to the Katana stage amp lineup. SDE-3000 delay, Phaser 90E, and Flanger 117E effects bring the total number to 58, and the Tone Setting memories have been doubled for even greater versatility while performing. The update also includes newly added channel and global EQs for refined tone-shaping, powerful Cabinet Resonance and Air Feel direct out functions derived from the Waza amp series, and many other great features. Katana Version 2 is a free, user-installable update for all Katana owners.

Katana-100 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 a huge selection of customizable effects and effect routing configurations with the BOSS Tone Studio editor software
  • Dedicated gain, EQ, presence, and effects controls for adjusting sounds quickly
  • Tone Setting 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

Katana Version 2 Additional Features:

  • Tone Setting memories increased from four to eight (two banks of four)
  • Access to 58 total effects (SDE-3000 delay, Phaser 90E, and Flanger 117E types added)
  • Full-time channel and global parametric EQs for refined tone shaping
  • Three Cabinet Resonance types adjust the interaction between the amp’s output section and speaker, enabling you to fine-tune the feel and tone of the amp
  • Cabinet simulation on the line, USB, and phones/recording outputs enhanced with three Air Feel settings for adding depth and dimension to direct tones
  • Reverb section now supports delay and delay-plus-reverb in addition to reverb only
  • Expanded send/return routing options for inserting external processing in the effects loop

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. A standout characteristic of every Katana amp is the dynamic interaction between its output section and the speaker, which provides the ultra-responsive musical experience that players crave. The Version 2 update adds an expressive Cabinet Resonance function derived from the flagship Waza amps, which allows you to customize this interaction for your touch with three resonance types. Delivering class-defying power, authoritative punch, and cutting presence that stands shoulder-to-shoulder with high-end amp designs, the Katana-100 is ready to meet the needs of 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, the Katana-100 lets you perform anywhere with just a guitar and amp. Connecting to BOSS Tone Studio via USB provides access to 58 fully-customizable effects, and you can load your favorites into the amp’s various effects sections. Going beyond standard distortion, delay, and reverb, the selection includes powerful tone-shapers like pitch shifting, ring mod, slicer, and many more. Newly added in Version 2, the SDE-3000 delay, Phaser 90E, and Flanger 117E effects provide classic sounds that are a perfect match for the Katana’s Brown channel tones. Additional updates include the ability to use delay and delay-plus-reverb in the Reverb section, plus enhanced send/return routing for using favorite pedals and other external processing in the amp’s effects loop.  

Tone Settings: One-Touch Recall of Custom Amp and Effects Setups
One of the Katana-100’s most powerful features is the ability to store favorite amp channel and effects setups in Tone Setting memories for instant recall. The Version 2 update adds a second bank of Tone Settings, doubling the number of available memories from four to eight. Combined with the newly added channel and global parametric EQs (configurable in BOSS Tone Studio), this elevates the Katana-100’s performance versatility to even higher levels. It’s easy to select Tone Settings and switch between the two banks from a panel button, or via an optional external footswitch 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. Familiar knobs for gain, three-band EQ, and presence let you quickly dial in your tone, just as you would with any standard amp. Essential effects parameters are adjusted with a simple knob twist, and Tone Settings can be stored with a brief button hold. And with the convenient Power Control, you can roll back the volume for small stages and home playing while retaining the expressive tone and feel of a cranked-up amp. The Katana-100 also features line, USB, and phones/recording outputs with cabinet simulation, allowing you to send mic’d up amp tones to a PA system, computer DAW, or headphones for quiet practice. Version 2 further enhances this capability with three Air Feel settings derived from the flagship Waza amps.

BOSS Tone Central

Great Effects Amp


My first modeling type amp, was recommended to me. Play at home on low setting, band rehearsal at 50 watt setting. I love that I can get pedal effects at my finger tips, love the "Brown" amp sound. Might upgrade to the 2x12 soon.




Nice with my gibson firebird


My first amp, not disappointed. Has really great tone. I am mostly a bass player but happy that I picked this up for my Gibson Firebird.

Perfect transaction!


The amp is everything I expected based on YouTube reviews.


Not far from Atlanta, GA


Great value


I may not have a lot of experience with playing but it's really easy to get that certain tone I want, i can easily get a nice crisp clean tone to a heavy metal tone in seconds

Boss has a reputation of putting out high quality guitar amplifiers and pedals for years and the Katana series is no exception to that universal law! Pushing out a whopping 100w this little amp is perfect for home use, studio, or even on the stage! With 5 different amp tone settings including clean, crunch, brown, and even acoustic this amp is ideal for all genres! They were even nice enough to include 15 different FX for you to enhance the already great tones for all applications! I could go on all day but in order for you to be as impressed as myself, go into Sam Ash today to pick one up!

The Kool Katana


I just played a club that holds about 300 using this amp and was very satisfied. After putting it through the paces in a live situation I would easily recommend this for the gigging guitarist. I ran the 100 watt full volume mode and kept it around 3 with the master volume up full in the clean mode. As I was using pedals, (The usual selection of overdrives and delays) I kept it in the default clean setting that comes right out of the box. The amp was mic'd with an sm57 and the speaker sounded great. Upon further inspection the variable output and full array of effects makes this a good choice for the home studio. Lightweight, loud and pretty inexpensive, I give it 5 stars.

Great Amp


I've played through this amp a number of times and I've always been impressed. the tones are just like the pedals! As a teacher this amp is versatile enough to allow me to play anything I need, and as a jazz guitarist its perfect for cleans and a lower range.

Versitile Amp


I've been using this amp to teach, and I love it. It's very easy to dial in a sound comparable to whatever I'm teaching, and I don't have to search through endless menus. But don't let it's size fool you. This little guy is plenty loud enough to rehearse with a band or live drummer. I would definitely recommend it as a practice, rehearsal, or even a backup amp.

DJ Jazzy Josh

Canoga Park, CA


very versatile


This amp will do literally every genre of music - anything from warm jazz tones to hard rock and metal. It's loud enough to play with heavy-handed drummers but by turning the master volume down you can easily get to bedroom sound levels. Lots of effects to play with, make sure you get the footswitch so you can easily turn them on and off.




Great Combo Amp!


This is one fantastic combo amp. It has very useable sounds and settings. The functions are very easy to switch between and very intuitive. The sounds are very realistic to what the true tube amp and effects sound like. I would recommend this to a friend. Great combo amp for all!
