Amplifiers for Electric Guitars
Flagship Tones, Crafted for Pro Players
Katana amps have received worldwide acclaim for their authentic tube tone and feel, onboard BOSS effects, and exceptional value. The flagship Katana-Artist combo takes Katana performance to new heights, offering all the latest series features along with numerous refinements tailored for the needs of professional players. Outfitted with a premium 12-inch Waza speaker, semi-closed cabinet, newly retuned amp characters, and much more, the 100-watt Katana-Artist is a powerhouse tone machine for all types of music, from blues, jazz, and country to the heaviest rock styles.
Katana Version 4: New Effects and Katana MkII Expansion Support
The Katana Version 4 update brings some great new features derived from the next-generation Katana MkII series. Heavy Octave, Stereo Delay, and Pan Delay effects have been added, along with a dedicated Pedal FX section that makes it easier to set up foot-controlled wah and pedal bend. In addition, a Katana-Artist or other 100-watt Katana model can now be used as a slave amp with the Katana MkII’s powerful Stereo Expand feature, allowing you to create wide, expansive tones with stereo-compatible effects distributed across both amps.

- About the Katana Amp Series
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.
- Refined Tones for Stage and Recording
Built for pro players, the 100-watt Katana-Artist combo features a new cabinet design with front-facing controls and a premium Waza 12-inch speaker. The semi-closed back is ideal for rock tones, and the tight, rugged construction produces rich, full sound with impressive projection. You can further tweak the response for your touch with the dedicated Cabinet Resonance control, which customizes the dynamic interaction between the amp’s output section and speaker. In addition, the sound and response of the Katana-Artist’s five amp characters have been fine-tuned to work in perfect harmony with the Waza speaker and new cabinet.
- Waza Speaker: Legendary Tone, Modern Power
A standout feature of the Katana-Artist is its custom Waza 12-inch speaker, which produces tones inspired by the benchmark 25-watt British stack speaker from the 1960s. BOSS set out to fully capture the rock speaker’s sought-after sound and response, but with the practical benefit of greatly increased power handling. Through detailed analysis of original speakers and careful selection of the magnet, cone material, and other construction elements, BOSS has fully realized this goal. Delivering rich, resonant tone with wide dynamic range, the Waza speaker brings the ultimate vintage rock sound to a compact 100-watt combo amp for the very first time.
- Five Original Amp Characters, Fine-Tuned for the Katana-Artist
Newly refined specifically for the Katana-Artist, five selectable 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-Artist lets you perform anywhere with just a guitar and amp. Connecting to BOSS Tone Studio via USB provides access to 65 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, channel and global EQs, and many more. There’s also an effects loop for patching in that external gear you can’t live without. And via BOSS Tone Studio, you’re able to move the loop’s position, adjust input/output gain, and select series/parallel operation as needed.
- Version 3 Effects and Control Features
Newly added with Version 3 are the Roland DC-30 Analog Chorus-Echo, BOSS GE-10 Graphic Equalizer, and 95E pedal wah effects types. These classics work great with any Katana amp character, but really dish up some special tonal magic when used in combination with the Brown character’s harmonically rich voice. The update also provides the ability to assign favorite parameters to the front-panel effects knobs, giving you greater flexibility for shaping your own unique effects tones on the fly. Additionally, you’re now able to control specific effects parameters from up to three expression pedals (connected via the rear panel and GA-FC foot controller), unlocking a new range of real-time command while performing.
- Tone Settings: One-Touch Recall of Custom Amp and Effects Setups
One of the Katana-Artist’s most powerful features is the ability to store favorite amp channel and effects setups in Tone Setting memories for instant recall. After you’ve dialed in a sound with the panel controls, simply save it to the desired memory with a quick button hold. Eight Tone Settings (two banks of four) are available, and you can easily select them from the panel. It’s also possible to use an optional external footswitch for hands-free control on the gig.
- Grab-and-Go Operation
While the Katana-Artist includes many advanced features, it’s amazingly simple to operate. Familiar controls for gain, presence, and the three-band tone stack let you dial in sounds quickly, while essential effects parameters are adjusted with a simple knob twist. And with the convenient Power Control, you’re able to roll back the overall volume while retaining the expressive tone and feel of a cranked-up amp.
- Ready-to-Mix Direct Tones with Air Feel
The Katana-Artist features line, USB, and phones/recording outputs with mic’d cabinet emulation, allowing you to send mix-ready amp tones to a PA system, computer DAW, or headphones. Using the panel’s Air Feel knob, the spatial character of the cab emulation can be instantly adjusted to suit different songs or styles. The Version 3 update further enhances the direct USB capabilities, offering true stereo sound with many of the Katana’s modulation, EQ, delay, and reverb effects, including the newly added DC-30 Analog Chorus-Echo.
- Free Patches and Editor Software
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.
