Boss Katana 100/212 Gen 3 Modelling Combo

BOSS Katana-100/212 Gen 3 — 100-Watt Modeling Combo with Evolved Tube Logic

This model pairs 100 watts of Class AB power with two custom 12-inch speakers and BOSS's evolved Tube Logic platform. Its 2x12 cabinet delivers the largest air-moving surface in the 100-watt Katana family, making it the natural choice for players who want stage volume without sacrificing the touch-sensitive response that defines the series.

What Sets This Combo Apart

Two features distinguish the BOSS Katana-100/212 Gen 3 from the rest of the Gen 3 lineup. The dedicated Power Amp In jack lets players bypass the internal preamp and use the reactive Class AB power section to amplify an external modeler or tube preamp at full 100 watts. Stereo Expand links two Katana amps for true stereo effects across both cabinets.

Power Section and Speaker Configuration

The reactive Class AB power stage is rated at 100 watts, the same architecture used across the flagship Katana series. Dual 12-inch custom speakers fill small-to-mid venues on their own, while the integrated Power Control switch steps output down to 0.5 W, Half, or Max without losing cranked-amp dynamics.

• The rated power output is 100 W Class AB, which provides gig-ready headroom with tube-style response.
• Speakers: 2 × 30 cm (12 in) custom — full-range cabinet voicing with stereo-ready dispersion
• Power Control — Standby / 0.5 W / Half / Max settings let you dial in cranked-amp dynamics at any output level

Amp Characters, Effects, and Tone Shaping

Six amp characters with a Variation switch deliver 12 voicings across four channel memories plus Panel mode, while five simultaneous effects categories — Booster, Mod, FX, Delay, and Reverb — give players 15 panel-accessible effects and over 60 types via BOSS Tone Studio. A dedicated Solo button delivers a clean boost at the end of the signal chain. Contour, Presence, and Cab Resonance provide global EQ shaping.

• Amp Characters: Acoustic / Clean / Pushed / Crunch / Lead / Brown — each with a selectable Variation
• Effects Sections: Booster / Mod / FX / Delay / Reverb — five simultaneous categories with Tap tempo
• Tone Memories — eight Tone Settings store and recall complete amp + effects setups

Connectivity, Recording, and Foot Control

The rear panel covers every modern workflow: Power Amp In, FX loop Send/Return, footswitch and expression pedal inputs, stereo headphone output, Line Out, USB-C, AUX IN, and a slot for the optional BOSS BT-DUAL Bluetooth adaptor. All outputs include IR cab simulation with three Air Feel types.

• Inputs: Power Amp In, Amp In (6.3 mm), Return, Footswitch, AUX IN — full integration with modelers and pedalboards
• Outputs: Line Out, Stereo Headphones, USB-C — IR-loaded cab sim on every direct output
• Dimensions / Weight: 670 × 248 × 484 mm / 19.8 kg — substantial 2x12 cabinet, AC-powered

Who Should Choose this Instrument

This instrument is the right choice for intermediate and gigging guitarists who need one amp covering practice, recording, and live performance. Upgraders from a starter combo or MkII Katana will appreciate the new Pushed voice, stereo headphone output, and Bluetooth adaptor support, while the FX loop and Power Amp In jack suit players with a modeler or tube preamp.

The BOSS Katana Series: A Decade of Tube Logic Evolution

The Katana series launched in 2016 as BOSS's first stage amplifier platform built around Tube Logic. Gen 3 introduces the Pushed amp character, an updated BOSS Tone Studio editor, and Bluetooth adaptor support across the range.
