Sonically enhanced with BOSS’s evolved Tube Logic technology, the BOSS Katana-50 Gen 3 packs a plethora of amplifier voices and ample effects into a seriously compact and portable combo. This 50-watt, 1 x 12-inch combo supplies you with six distinct amplifier personalities to play with, including Gen 3’s all-new addition of a dynamic edge-of-breakup tone in the “Pushed” voice. Plus, a quick press of the Variation switch unlocks a voice-specific tonal alternative for a grand total of 12 amplifier tonalities. Music Experiences BOSS pedal fanatics love how the Katana-50 Gen 3’s five independent effects sections deliver a library’s worth of classic stompbox-inspired effects, from spacious ’verbs to ethereal echoes. You also get a powerful 3-band EQ to tweak your tone, in addition to four Tone Setting memories to save your favorite amp/effect combinations for instant recall. It’s all finished off with BOSS’ Gen 3 Tone Studio, a stereo headphone jack, a cab-sim-emulated USB out, and a low-wattage Power Control that allows for cranked-up tones at any volume level. Perfect for practice sessions, home studio setups, and even casual gigging, the BOSS Katana-50 Gen 3 is ready to excel as the centerpiece of your next rig.
The Katana Gen 3 series comes swinging right out of the gate with a newly evolved and enhanced iteration of BOSS’s revered Tube Logic technology, capturing all the harmonic nuance and dynamic feel of a true tube amplifier. These improvements elevate all the Katana series’ prior amplifier models to a whole new level of valve-inspired realism, but the technology is truly on full display in Gen 3’s all-new amplifier typed: Pushed. Engineered to exactly replicate the ever-coveted edge-of-breakup sound, the Pushed amp character artfully embodies the touch-sensitive gain characteristics and lively dynamics of a clean tube combo cranked to its breaking point. Furthermore, the Katana’s third generation comes complete with a whole host of improvements to the BOSS Tone Studio, including UI and editing upgrades for a quicker, more straightforward workflow.
In addition to Generation 3’s new Pushed amp, this Katana contains all five of the MkII series’ time-tested amplifier voices, all optimized by BOSS’s evolved Tube Logic technology. Lead, Crunch, and Pushed are all aimed to please dirt-obsessed players with a wealth of remarkably tube-like tones, and you even get a “Brown” voice that delivers screaming ’80s hard-rock sounds in spades. On the opposite end of the spectrum, the Katana Gen 3 series boasts a lush, full-bodied Clean voice and an Acoustic voice to accommodate your acoustic-electric arsenal. It all adds up to a grand total of six amplifiers to choose from, but that’s only half the story — a Variation switch effectively doubles the amp tones at your disposal with distinct sonic spins on each amp’s sound!.
While previous Katana amplifiers required a USB connection to access the editor, each model in the third generation now comes equipped with a dedicated jack on the back to connect with the optional BOSS BT-DUAL Bluetooth Audio MIDI Dual Adapter. This adapter allows you to make instant on-the-fly edits to your Katana’s tone straight from your mobile device. Plus, you can also use it to stream songs and backing tracks to make the most of your woodshedding sessions!.

Loaded with inspiring tone tools and diverse connectivity options, Katana Gen 3 is your indispensable centerpiece for studio recording, live performance, and daily practice. The Katana-50 Gen 3 model strikes the perfect balance of punch and portability, offering 50 watts of Class AB power in a compact 1x12 combo.
Unbound Backed by our advanced Tube Logic amplifier architecture and reactive Class AB power, the BOSS Katana series has become a standard for guitarists everywhere since its introduction in 2016. Katana amps embody decades of BOSS development knowledge, providing professional, tube-inspired sound coupled with modern advantages like onboard effects, one-touch memory recall, deep sound customization, and reduced weight. Katana Gen 3 elevates the lineup with even more range and versatility, bringing you a playing experience that goes where no other amps can.
Tones Tube Logic recreates tube circuitry and all its complex interactions at a component level, putting the coveted tone and feel of classic tube amp designs under your fingers. Our approach continues to evolve with refinements to the five amp characters available in previous Katana models, including the iconic high-gain Brown type. The new Pushed character spotlights internal dynamic enhancements with the pleasing touch-responsive gain of a clean combo driven into harmonic saturation. All six amp characters include a selectable variation, giving you 12 distinctive tones to support every musical style.
As every tube amp lover knows, the sound becomes richer, fuller, and more responsive as you turn up the volume. Unfortunately, it also gets way too loud for many playing situations. An external power attenuator is a common solution, but it can introduce artifacts that color the amp’s tone and feel. The integrated Power Control in Katana Gen 3 delivers the best of all worlds, letting you dial in cranked-amp inspiration with no adverse effect on the sound. Just turn the panel knob to transparently harness the level for everything from live stage playing to daily bedroom jams.
Katana Gen 3 features five simultaneous effect categories loaded with essential selections from the historic BOSS library. Booster, Mod, FX, Delay, and Reverb sections offer enhanced sound quality, grab-and-go parameter controls, and three variations each for access to 15 unique effects. BOSS Tone Studio unlocks additional possibilities, allowing you to customize the onboard effects from 60 different types and tweak deep options not available from the amp’s panel. And when the optional Bluetooth® Audio MIDI Dual Adaptor is installed, you can wirelessly edit sounds on the gig using the BTS editor app on your smartphone.
BOSS Tone Studio for Katana Gen 3 offers new visual enhancements and graphic customization options that make crafting your tone faster and more intuitive. Explore amp and effect editing tools, change the effect order, and shape the overall sound with the three-way Contour control and multiple EQs. Dial in system-wide settings and behaviors. And organize custom setups for all your gigs. You also have access to BOSS Tone Exchange, where you can download pro setups and share sounds with the worldwide Katana community.
Katana-50 Gen 3 offers several powerful tools for controlling your sounds. Four Tone Setting memories let you store complete amp/effect setups and recall them with a touch. And with footswitches and an expression pedal, you can remotely switch memories and control a variety of custom assignments that you’ve set up in BOSS Tone Studio.
Along with its self-contained operation, Katana-50 Gen 3 is also a great monitor for an external setup such as a direct-to-PA pedalboard. Simply connect to the Power Amp In jack to bypass the Katana preamp and use the reactive Class AB power section to amplify any modeler or external preamp.
Katana-50 Gen 3 includes connectivity to meet every need. Plug in headphones to practice quietly with stereo sound. And record to your favorite music software on computers and mobile devices over USB-C. All audio outputs feature IR-based cabinet sound for great direct tone, with three Air Feel types and two customizable settings in BOSS Tone Studio.
