Whether you're practicing at home, recording directly to your computer, rehearsing with a band, or performing live, the Katana-50 MkII EX provides exceptional tone, intuitive operation, and professional connectivity in a portable and road-ready design.
Tube Logic Technology for Authentic Amp Feel
At the heart of the Katana-50 MkII EX is BOSS's advanced Tube Logic design philosophy. Rather than simply modeling amplifier sounds, Tube Logic recreates the complete behavior of traditional tube amplifiers, including gain structure, dynamic response, power amp interaction, and speaker characteristics. The result is an amplifier that responds naturally to your picking dynamics and guitar volume controls while delivering inspiring feel and expressive performance.
From sparkling cleans to high-gain lead tones, every amp voice reacts with remarkable realism, making the Katana-50 MkII EX suitable for players who demand authentic performance without the maintenance of traditional tube amplifiers.
Five Amp Characters with Ten Total Voices
The Katana-50 MkII EX includes five core amplifier types, each featuring an additional variation for even greater tonal flexibility. This provides ten distinct amplifier voices capable of covering virtually any musical genre.
- Acoustic – Optimized for acoustic-electric guitars with natural, transparent sound.
- Clean – Rich, full-bodied clean tones with excellent headroom.
- Crunch – Dynamic vintage-inspired overdrive for blues and classic rock.
- Lead – Smooth sustain and focused gain for expressive solos.
- Brown – High-gain modern distortion with powerful punch and tight low end.
Each amp character includes a selectable variation, doubling the available tonal palette and allowing players to create personalized sounds for virtually any playing style.
Legendary BOSS Effects Built In
The Katana-50 MkII EX places an entire pedalboard inside the amplifier with five independent effects sections that can operate simultaneously. Factory-installed effects are immediately available from the front panel, while deeper editing through BOSS Tone Studio unlocks over 60 professional BOSS effects.
- Booster
- Modulation
- FX
- Delay
- Reverb
Effects routing, parameters, EQ settings, cabinet resonance, and numerous advanced options can all be customized through BOSS Tone Studio, allowing players to create highly personalized performance presets.
Expanded Performance Features for Serious Players
The MkII EX version introduces several enhancements that make it even more suitable for live performance compared to the standard Katana-50 MkII. Compatibility with the optional GA-FC and GA-FC EX foot controllers enables hands-free switching between Tone Settings, effect activation, and expression pedal control. A dedicated Line Out with cabinet emulation allows direct connection to a PA system while keeping the internal speaker active, making stage setups faster and more flexible.
Stereo Expand functionality also allows the amplifier to link with another compatible Katana MkII amplifier, creating an immersive stereo rig for spacious modulation, delay, and reverb effects.
Store and Recall Custom Tone Settings
Create your perfect sound once and recall it instantly whenever you need it. The Katana-50 MkII EX includes four onboard Tone Setting memories that store complete amplifier and effects configurations. When paired with compatible foot controllers, even more memory access becomes available for seamless transitions during live performances.
This feature is ideal for musicians who require multiple sounds throughout a performance without manually adjusting controls between songs.
Power Control for Any Playing Environment
Achieving the rich sound of a driven amplifier doesn't always require high stage volume. The integrated Power Control function lets you select output levels that suit your environment while preserving the amplifier's natural response and feel. Whether you're practicing quietly at home or performing on stage, you can enjoy consistent Tube Logic tone at virtually any volume.
Designed for Recording, Streaming, and Live Performance
The Katana-50 MkII EX offers extensive connectivity for modern musicians. The USB interface enables high-quality direct recording to a computer, while the Line Out and Phones/Recording outputs provide cabinet-emulated sound suitable for live sound systems, recording interfaces, silent practice, and content creation. Three selectable Air Feel cabinet simulation options further refine your direct output tone using BOSS Tone Studio.
The dedicated Power Amp In also allows the amplifier to function as a powered cabinet for external amp modelers, multi-effects processors, and preamps, expanding its versatility even further.
Compact Design with Professional Reliability
Despite its powerful capabilities, the Katana-50 MkII EX remains lightweight and portable, making it an excellent choice for rehearsals, gigs, studio sessions, teaching environments, and home practice.
