Boss Katana 100/212 Gen 3 Modellering Combo

100-Watt Modeling Combo with Tube Logic Expressiveness

The Boss Katana 100/212 Gen 3 delivers 100 watts of Class AB power through two custom 12-inch speakers, using BOSS Tube Logic to model tube circuitry at the component level for authentic touch sensitivity and harmonic richness. This third-generation Katana introduces the Pushed amp character alongside five refined voices, eight Tone Setting memories, and five simultaneous effects sections — a complete platform for stage, studio, and home practice.

Pushed Amp Character and Evolved Tube Logic

Filling the gap between Clean and Crunch, the Pushed amp type replicates the touch-responsive gain of a clean tube combo driven into harmonic saturation — that coveted edge-of-breakup territory. All six amp characters (Acoustic, Clean, Pushed, Crunch, Lead, Brown) include a selectable variation, doubling the tonal palette to 12 distinct sounds without menu diving.

Class AB Power and Dual 12-Inch Speakers

Unlike Class D switching designs, the reactive Class AB power section interacts with the speakers like a tube amp, producing organic feel that opens up as the master volume increases.

• Rated Power Output: 100 W — sufficient headroom for medium stages without PA reinforcement
• Dual 30 cm custom BOSS Katana speakers provide a wide soundstage and deep, full low-end response in real-world venues.
• Power Control: Standby, 0.5 W, Half, Max — transparent attenuation so cranked-amp tone and compression remain achievable at bedroom volumes

Five Effects Sections and Flexible Tone Shaping

Each of the five effects categories — Booster, Mod, FX, Delay, Reverb — runs simultaneously with three panel-selectable variations, while the BOSS Tone Studio app unlocks over 60 effect types including classic overdrives, tape delays, spring reverbs, and modulation. The three-way Contour switch reshapes the overall frequency curve for rhythm, lead, or clean American voicing without touching the Bass, Middle, or Treble knobs.

• Contour: 3-way switch — global EQ curves adjustable per Tone Setting for instant tonal shifts
• Cabinet Resonance can be set to Vintage, Modern, or Deep, adapting the low-end feel for different speakers and styles.
• Tone Settings: 8 memories — store and recall full amp and effect setups for instant access mid-set

Stage and Studio Connectivity

A Power Amp In jack bypasses the preamp entirely, routing external modelers directly into the Class AB power section. The effects loop accommodates time-based pedals, while the stereo headphone output and USB-C connection both feature IR-based cabinet simulation with three Air Feel options for realistic direct tone.

• Connect external pedals through the effects loop using Send and Return jacks, expanding your tonal possibilities between preamp and power amp.
• Stereo Expand: link two Katana Gen 3 or MkII amps — distribute stereo chorus, delay, and reverb across both cabinets
• Footswitch I/O: GA-FC / GA-FC EX compatible — remote control of Tone Settings, effects on/off, expression pedal, and Solo boost

Gigging Guitarists and Home Players Who Need One Amp for Everything

This model is ideal for gigging guitarists who need a single combo covering cleans, crunch, high-gain, and acoustic-electric tones without carrying multiple amplifiers. Cover band musicians benefit from eight Tone Setting memories and footswitch control for instant transitions between radically different sounds mid-set. The Power Control and stereo headphone output make it equally practical for silent apartment practice, while the Power Amp In serves players who already own external modelers or tube preamps.

BOSS Katana: A Modern Classic Since 2016

Since its 2016 introduction, the BOSS Katana series has been adopted by over one million players worldwide. Built on decades of BOSS effects development and proprietary Tube Logic architecture, each generation refines the core platform while maintaining full compatibility with sounds created on previous Katana models. Gen 3 brings evolved Tube Logic enhancements, the new Pushed amp character, an updated BOSS Tone Studio editor, and stereo headphone output to the most successful modeling amplifier line in the industry.
