Get to know them!

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. Sweetwater’s 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’s 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.

What’s new for Gen 3?

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 type: 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.

12 amp voices to explore

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 tubelike 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!

Wireless control via BOSS’s optional Bluetooth adapter

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 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!

Power Amp In(put)

Got a floor unit or tube preamp you can’t live without? You can access all 50 watts of the Katana-50 Gen 3’s Class AB power section using the power amp input. Here, you bypass everything before the power amp, so what you hear is exactly what you expect — only live and in living color.

Powered by the Gen 3 BOSS Tone Studio editor

Upgraded with an enhanced UI and editing options for Gen 3, the Katana-50 Gen 3 supports over 60 timeless BOSS effects, and you can load an entire series of them for instant access. The amp's Booster/Mod, FX/Delay, and Reverb controls give you easy 1-knob access to up to five simultaneous effects types, with a color-coded button to switch between preset effects. To completely customize your effects and amp settings, connect the Katana-50 Gen 3 to your computer via USB and load up the Tone Studio software. Here, you can create your own setup or download setups created by pro guitarists at the BOSS Tone Studio website. Best of all, the Katana-50 Gen 3 can store multiple custom amp and effects profiles for instant recall, making this combo a versatile multichannel amplifier.
