(Open Box) Boss - Katana Artist MkI
Professional 100-watt combo amp
Introducing the ‘Katana-Artist MKI’ from Boss.
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.
Legendary Sound For Professional Performers
providing ultimate response with speaker and cabThe Katana-Artist has been designed with unique nuances for the discerning pro players. Boss’s custom ‘Waza’ speaker delivers the quintessential rock sound under your fingers, whilst the cabinet’s wide baffle and semi-closed back provides tight, crunching tones with warm low end, a broad mid-range and crystal-clear highs.
Furthermore, each Katana-Artist MKI amp character has been specifically voiced to provide the ultimate response with the speaker and cab.
Waza Speaker: Legendary Tone, Modern Power
Powerful, Classic ToneAn integral element to the Katan-Artist MKI’s huge sound is the inclusion of the 12” Waza speaker, designed and engineered in-house by Boss to give a broad dynamic response, smooth midrange, and warm harmonic overtones of the benchmark 25-watt British stack speaker from the 1960’s heyday.
Via in-depth analysis of original speakers and careful selection of the magnet, cone material and various other elements, the Waza speaker encapsulates the full characteristics of this iconic speaker whilst boosting power capacity to 100 watts.
One-Touch Recall Of Custom Setups
CALL UP YOUR FAVOURITE TONES IN NO TIME Thanks to the Katana MKI’s onboard Tone setting banks, you’re able to save your favourite amp character and effects settings for immediate recall.
After you’ve dialled in your tone of choice with the panel controls, just save it to your preferred memory with a quick button hold. Eight tone settings (2 banks of 4) are available, with quick selection straight from the panel.
Should you need hands-free operation, simply connect the GA-FC foot controller.
Incredible Amp Characters & Effects
HUGE VARIETY OF EFFECTSThe Katana-Artist MKI features up to 10 differing tone options, with 5 simultaneous effects categories, you have the sound-shaping power of an extensive pedalboard, inside the Katana MKI.
If that’s not enough to whet your appetite, try connecting to Boss ‘Tone Studio’ to dive head first into a plethora of effects and tone heaven. Customise the sections with 60+different effect types, tweak the order with 4 different chains and so much more.
Deep Tone-Shaping ToolsUpon first glance of the Katana MKII’s front panel, you may notice some differences from Katana’s previous incarnation. The Katana MKII features some exclusive additions, such as a 3-way contour switch which allows you mould the amp’s core tone, whilst 3 selectable Global EQ settings (adjustable in Tone Studio) are perfect for making small adjustments over the overall sound for different guitars and styles. A post-amp solo boost controlled via footswitch is also available featuring a dedicated panel knob for quick-time adjustment.
BOSS Tone Studio Enhancements
IN DEPTH EDITINGBOSS Tone Studio has also evolved alongside the Katana MKI amplifiers. The interface has been updated with a refreshed look, and many parameters have been consolidated into the main screen for faster workflow.
There's also a dedicated Pedal FX category, making it easier to assign wah and pedal bend effects to a connected expression pedal. And if you're a first-gen Katana owner, it's possible to import your custom patches and use them all with the Katana-Artist MKI.
Compact Gig Commander
hands free operationThe optional GA-FC foot controller is the perfect partner for the Katana-Artist MkI—it connects with a single cable, requires no external power, and has a slim, rugged profile that takes up minimal space.
With six footswitches, you can recall Tone Settings and turn the five effects sections on/off. The GA-FC also supports external footswitches and expression pedals, with default assignments that include tap tempo, bank selection, foot volume, and Pedal FX.
Assignments can be customized via BOSS Tone Studio, including pedal control of up to three parameters at once.
