Boss Katana 100 Gen 3 1x12 100w Combo

The BOSS KATANA Gen 3 lineup has arrived, featuring a new amp character, enhanced Tube Logic technology, refined tone memory, and an updated app—reaffirming its status as the ultimate amplifier for today’s guitarist. This 100-watt combo amp is compact yet powerful, equipped with a custom 12-inch speaker, 12 versatile amp characters, built-in BOSS effects, and an impressive app for deep tone shaping. Add the optional BOSS BT-DUAL Bluetooth Adapter, and you can easily tweak settings and stream audio directly from your smartphone.

Expansion Possibilities
The KATANA Gen 3 100-watt Combo is ready to grow with your setup. It features inputs for up to two footswitches and an expression pedal, giving you hands-free control on stage or in the studio. Add the optional BT-DUAL Bluetooth Audio MIDI Adapter, and you can wirelessly stream audio from your mobile device and edit tones remotely using the BOSS Tone Studio app.

Revamped BOSS Tone Studio
The redesigned BOSS Tone Studio software now features an updated, more intuitive interface for easier navigation and workflow. Explore over 60 high-quality BOSS effects, customize your sound with deep editing tools, rearrange effect chains, tweak advanced parameters, and organize your tones with live set creation for different playing scenarios.

Cranked Amp Feel at Any Volume
Every tube amp fan knows that the magic happens when the volume is pushed—but that’s not always practical. The KATANA Gen 3’s built-in Power Control lets you achieve that powerful, responsive tone at manageable volumes, maintaining full tonal integrity no matter how loud or quiet you play.

Iconic BOSS Effects, Built Right In
Five simultaneous effect sections—Booster, Modulation, FX, Delay, and Reverb—give you immediate access to core BOSS tones. Each section includes three variations, allowing for a total of 15 on-board effects with upgraded sound quality and intuitive controls for fast, flexible tone shaping.

Next-Level Sound Customization
The BOSS Tone Studio for KATANA Gen 3 goes further than ever with visual enhancements and advanced editing features. Rearrange effects, fine-tune amp settings, and shape your tone using the three-way Contour switch, multiple EQ options, and graphic tools designed for fast, personalized results.

Total Tone Management
Take full command of your sound with four Tone Setting memories that let you store and instantly recall complete amp and effect configurations. Connect optional footswitches or an expression pedal to remotely change presets, toggle effects, or control custom parameters—all set up through the Tone Studio app.

Ideal for Modelers and Pedalboards
Beyond being a powerful standalone amp, the KATANA Gen 3 is a perfect partner for external gear. Use the Power Amp In jack to bypass the internal preamp and run your favorite modelers or preamp pedals straight into the reactive Class AB power section for authentic amp feel and performance.
