Using the optional GA-FC foot controller turns the Katana into a formidable performance tool, with access to all eight patches, volume control and an assignable expression pedal. The Katana’s effects are good enough to replace many pedalboards, however stompbox diehards will also enjoy the Artist’s loop, which can be remotely switched in and out from the foot controller or MIDI. 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

BOSS Tone Studio has also evolved alongside the Katana MkII 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 MkII. KATANA MKII VERSION 2—NEW CREATIVE TOOLS The effects section follows the same pattern as other Katanas with two split rotary level controls - one for boost and mod effects, the other for Delay and FX - and a third un-split level control dedicated to reverb. Above each level knob is a small button switch that accesses three pre-loaded choices for each effect position, colour-coded by an LED that lights up in red, green or yellow. There’s also a tiny illuminated tap-tempo switch for manual delay time setting. Mic'd cabinet emulation on the line, USB, and phones/recording outputs, with three Air Feel settings available in BOSS Tone Studio By looking and studying original speakers with careful selection of components, the Waza speaker fully expresses the essence of this legendary speaker, while raising the capacity to 100 watts. The Boss Katana MKII takes all the amazing features from the MKI, and takes it to the next level. We have added more effects, 10x amp voicings, a specific power amp input for amp modellers/multi-fx units and we have added the ability to link two Katana Amps together for a stereo rig. The Katana Range has become one of the most favoured amp ranges on the market, due to its incredible tone, feel and response.Contour Settings—Shape your core tone with three different Contour settings, each with four customizable frequency curves to choose from. External control support via GA-FC/GA-FC EX foot controller, footswitches, expression pedal, and MIDI

As well as the 10 natural-sounding amp models within the Katana Range, there is a whopping 60+ effects to choose from, which can be fully edited with the free Boss Tone Studio software for Mac and PC. Imagine having a pedalboard with 60+ pedals at your disposal! Each Katana model can have your favourite patches stored directly to the amp (x4 KTN-50 & x8 KTN-100 Upwards), 15 effects can be stored per patch. You can also control the effects and amp models with the use of an external footswitch (FS-6 for KTN-50 and GA-FC for KTN-100 Upwards). An updated look and a streamlined interface lead to a more efficient workflow. For example, the separate Pedal FX category means you can assign pedal/wah effects etc to your connected expression pedal. Custom patches can be imported and used with the Katana-Artist MKII as well!
