The Evolution of a Modern Classic

Katana MkII takes the acclaimed Katana guitar amp series to the next level, turbocharging the core platform with more sounds, more effects, and more features. Newly voiced variations are now available for all five amp characters, doubling the tonal options. And the onboard effects categories have been expanded from three to five, providing even more real-time processing to choose from. The usability has been ramped up too, with a power amp input for modelers and multi-FX, updated editor software, and many other enhancements.

More Sounds, More Versatility

The stage-class Katana MkII lineup picks up where the first generation
left off, building on the same core tones and features that have made
the series such a worldwide smash. If you loved the original Katana
amps, you'll love Katana MkII even more. And if you're new to the party,
get ready for sound, feel, and versatility that soars far beyond its price class.

Five Amp Characters,
Ten Overall Tones

Katana MkII's five primary amp characters offer everything from organic
vintage tones to modern high-gain sounds, plus a dedicated voice optimized
for acoustic-electric guitar. The characters have now been extended with
newly voiced variations, providing a wider palette of tone options to craft
your personal sound.

Five Effects at Once

Katana MkII now includes five simultaneous effects categories, putting
the tone-shaping power of a massive pedalboard right inside your amp.
Independent Booster, Mod, FX, Delay, and Reverb sections come loaded
from the factory with three variations in each, providing 15 ready-to-play
effects to choose from. Connecting to BOSS Tone Studio lets you dive
much deeper if you want—customize the sections with over 60 different
effect types, change the order with four different chains, and much more.

Full-Throttle Sound
Every Time You Plug In

Backed by BOSS's Tube Logic approach, Katana MkII delivers the authentic
output distortion characteristics of genuine tube amplifiers, with the sound
and feel becoming richer and more responsive as you turn up the volume.
But unlike that classic tube amp, Katana MkII's variable Power Control makes
it easy to fly in the sweet spot without getting fired from the gig or kicked out
of the house. Just throttle back the overall volume as needed to enjoy inspiring, cranked-amp sound anywhere you play, from bedroom to stage.

Amplify Your External Gear

The Katana-50 MkII rocks as a standalone amp, but it also excels as a
powered cabinet for a favorite preamp, modeler, or multi-effects unit.
Connecting to the rear-panel Power Amp In jack bypasses Katana MkII's
preamp and effects, letting you tap straight into the Tube Logic power section, complete with grab-and-go Power Control. And with BOSS Tone Studio,
the input can be easily optimized for your particular gear with a high-pass
filter and adjustable gain.

One-Touch Recall of
Custom Setups

One of the Katana-50 MkII's most powerful features is the ability to store
favorite amp character and effects setups in Tone Setting memories for
instant recall. After you've dialed in a sound with the panel controls, simply
save it to the desired memory with a quick button hold. Four Tone Settings
(two banks of two) are available, with fast selection right from the panel.
It's also possible to connect external footswitches for hands-free control
on the gig.

Stereo Made Easy

One Katana MkII sounds great, but playing two at once is even better.
The new Stereo Expand feature makes linking two amps simple, with just
one regular cable needed. You're able to control everything from the
master Katana MkII, with stereo-compatible effects like chorus, delay,
reverb, and others distributed across both amps for a wide, immersive
sound field. Stereo Expand is supported on all 100-watt Katana MkII models.

Ready-to-Mix Direct Tones

The Katana-50 MkII features USB and phones/recording outputs with
mic'd cabinet emulation, letting you send mix-ready amp tones to a computer
DAW or headphones. The direct sound can be shaped with three different
Air Feel settings, which are accessible from BOSS Tone Studio. Two-channel
USB operation is supported, allowing you to track in true stereo with many of Katana's modulation, EQ, delay, and reverb effects.

Compact Gig Commander

The optional GA-FC foot controller is the perfect partner for the Katana-100
MkII. It connects with a single cable, requires no external power, and features
a slim, rugged profile that takes up minimal space. With six footswitches,
you can directly recall Tone Settings and independently turn the five effects sections on/off. The GA-FC also supports external footswitches and expression pedals, with default assignments that include tap tempo, bank selection,
foot volume, and Pedal FX. A large variety of custom assignments are
available via BOSS Tone Studio, including expression pedal control of up
to three parameters at once.

BOSS Tone Studio

BOSS Tone Studio has also evolved alongside the Katana MkII amplifiers.
The interface has been updated with a refreshed look, and a number of parameters have been consolidated into the main screen for faster workflow. There's also a dedicated Pedal FX category, making it easier to assign wah
and pedal bend effects to a connected expression pedal. And if you're a
first-gen Katana owner, it's possible to import your custom patches and
use them all with Katana MkII.
