The Boss Katana-50 MkII is a versatile 50-watt modelling guitar amplifier designed to cover everything from clean practice tones and classic crunch through to high-gain rock, ambient effects and direct recording.

Its combination of Clean, Crunch, Lead, Brown and Acoustic amp types, onboard Booster, Mod, FX, Delay and Reverb sections, plus BOSS Tone Studio connectivity makes it suitable for home practice, rehearsal, recording and live performance.

WHY YOU’LL LOVE IT

The Katana-50 MkII is popular because it can cover an enormous range of sounds without requiring a large pedalboard or complicated setup.

At home, the 0.5-watt Power Control setting allows convincing driven tones at sensible volume.

At rehearsal or on stage, the full 50-watt mode and 12" speaker provide considerably more projection and headroom.

Its onboard effects and Tone Setting memories also make it easy to save complete sounds for quick recall.

DETAILED FEATURES & BENEFITS

50-Watt Output

The Katana-50 MkII delivers up to 50 watts through its custom 12" speaker.

This gives it enough power for rehearsals and many live situations while still remaining manageable for home use.

Custom 12" Speaker

The amplifier uses a dedicated 12" Boss speaker designed specifically for the Katana platform.

It provides the full-range response needed to handle the amp’s wide variety of clean, driven and effected sounds.

FIVE AMP CHARACTERS

The Katana-50 MkII provides five core amp types:

• Acoustic

• Clean

• Crunch

• Lead

• Brown

Each amp type also has a selectable Variation, effectively doubling the available core voices.

Clean

Clean mode provides clear headroom and works well for pedals, chorus, delay and reverb.

Crunch

Crunch mode provides classic low-to-medium gain drive for blues, rock and rhythm playing.

Lead

Lead mode delivers higher gain and sustain for heavier rhythm and lead work.

Brown

Brown mode provides the most aggressive high-gain response and is particularly well suited to hard rock and metal.

Acoustic

Acoustic mode is designed for electro-acoustic guitar and other full-range clean applications.

FIVE SIMULTANEOUS EFFECTS SECTIONS

The MkII platform provides five independent effects categories:

• Booster

• Mod

• FX

• Delay

• Reverb

Each category has three selectable variations directly from the panel.

Additional effects and deeper editing are available through BOSS Tone Studio.

BOSS TONE STUDIO

Connecting the amplifier to a computer via USB unlocks deeper control using BOSS Tone Studio.

This allows access to:

• More than 60 Boss effects

• Effect routing

• Channel EQ

• Global EQ

• Cab Resonance options

• Air Feel settings

• Tone Setting management

• Downloadable Livesets

This significantly expands the amplifier beyond the sounds available directly from the front panel.

FOUR TONE SETTING MEMORIES

The Katana-50 MkII can store four complete Tone Settings.

These can save amp type, gain, EQ and effects settings for fast recall.

This is particularly useful for players who need different sounds for clean rhythm, crunch, lead and ambient sections.

POWER CONTROL

The rear power section can operate at:

• Standby

• 0.5W

• 25W

• 50W

This allows the amplifier to retain its driven feel and response at much lower listening levels.

POWER AMP IN

The Power Amp In bypasses the Katana preamp and onboard effects.

This allows an external:

• Modeller

• Multi-effects unit

• Preamp pedal

to feed directly into the Katana power section and speaker.

USB RECORDING

The USB connection allows the Katana to integrate directly with compatible computer recording setups.

The USB and Phones / Recording outputs include cabinet emulation, allowing usable direct-recorded guitar tones without placing a microphone in front of the speaker.

AUX INPUT

The stereo mini-jack Aux Input allows backing tracks, music players and other compatible audio devices to be connected for practice.

EXTERNAL CONTROL

The rear-panel control connection supports compatible Boss footswitches or an expression pedal.

This allows hands-free Tone Setting selection and other control options depending on the connected accessory.

• Home practice

HOW IT COMPARES

Katana-50 MkII vs Original Katana-50

The MkII expands the original Katana platform with Variation settings for all five amp characters, five independent effects categories and a dedicated Power Amp In.

Katana-50 MkII vs Traditional Practice Amp

A conventional practice amp may offer only one or two channels and limited effects.

The Katana provides multiple amp characters, extensive effects, memory storage and direct recording features.

Katana-50 MkII vs Larger Katana Models

Larger Katana models provide greater power, additional connectivity and, in some cases, more advanced switching options.

The 50 MkII focuses on portability and value while retaining the core Katana sound platform.

FAIR DEAL MUSIC EXPERT VERDICT ★★★★★

Best suited for: Players wanting one affordable amplifier that can handle home practice, rehearsal, effects-heavy playing and direct recording.

Customers usually upgrade from: Small starter amps, compact practice combos and entry-level modelling amplifiers.

Most commonly paired with: Electric guitars, external footswitches, expression pedals, multi-effects units and USB recording setups.

Our tip: Use the 0.5W setting at home and turn the Master Volume higher rather than running the 50W setting extremely low. This helps retain more of the Katana’s responsive feel at manageable room volume.

Showroom feedback: The Katana-50 MkII remains a particularly strong all-rounder because the front panel is simple enough for immediate use, while Tone Studio offers far deeper control when required.
