BOSS KATANA-MINI Portable Guitar Amplifier

BOSS KATANA-MINI Guitar Amplifier – Big Katana Tone in an Ultra-Portable Design

The BOSS KATANA-MINI Guitar Amplifier brings the acclaimed sound and responsiveness of the renowned Katana amplifier series into an ultra-compact, battery-powered practice amp. Designed for guitarists who want premium tone wherever inspiration strikes, the KATANA-MINI combines authentic analog circuitry, three versatile amp voices, a powerful three-band EQ, and a warm tape-style delay in a lightweight, travel-friendly enclosure. Whether you're practicing at home, jamming with friends, teaching lessons, or playing on the go, the KATANA-MINI delivers impressive sound quality that exceeds expectations for its size.

Authentic Katana Analog Tone

Unlike many compact practice amplifiers that rely on basic digital processing, the KATANA-MINI features an authentic multi-stage analog gain circuit inspired by BOSS's acclaimed Katana amplifier architecture. This design produces dynamic response, natural feel, and expressive overdrive while preserving clarity across different playing styles.

From sparkling clean tones to crunchy rhythm sounds and modern high-gain lead tones, the amplifier responds naturally to your guitar's volume controls and playing dynamics, providing an inspiring experience for practice and performance.

Three Versatile Amp Characters

A simple front-panel selector provides instant access to three carefully voiced amplifier types, making it easy to adapt to different musical genres and playing techniques.

• Brown: High-gain modern lead tone with rich sustain.
• Crunch: Classic overdriven sound for blues, rock, and rhythm playing.
• Clean: Clear, balanced tone ideal for clean passages, pedals, and dynamic performance.

Powerful Three-Band Analog Equalizer

The integrated Bass, Middle, and Treble EQ controls allow precise tonal shaping, enabling players to customize their sound for different guitars, pickups, and musical styles. Unlike many compact practice amps with limited tone controls, the KATANA-MINI offers the flexibility needed to create professional-quality tones in virtually any environment.

Built-In Tape-Style Delay

The onboard analog-style delay effect adds warmth, depth, and ambience without requiring external pedals. Independent Time and Level controls allow players to dial in subtle room ambience, slapback echo, or longer delay effects for lead playing and atmospheric textures.

Compact Size with Powerful Sound

Despite its remarkably small footprint, the KATANA-MINI delivers full-bodied guitar tone through a specially designed 4-inch custom speaker. Every component has been carefully engineered to maximize sound quality, producing impressive clarity, punch, and projection for home practice, rehearsals, and portable playing.

The lightweight cabinet includes an integrated carrying handle, making it easy to transport between home, rehearsals, classrooms, or outdoor practice sessions.

Battery or AC Powered Flexibility

The KATANA-MINI operates using six AA batteries or an optional BOSS PSB-series AC adaptor, providing exceptional flexibility for musicians who want to play virtually anywhere. Battery operation makes it an ideal companion for travel, outdoor performances, backstage warm-ups, and locations without convenient power access.

Practice, Recording, and Jamming Features

The amplifier includes a dedicated AUX input for connecting smartphones, tablets, music players, or other audio devices, allowing players to practice along with backing tracks, lessons, or favorite songs.

A Phones/Recording Output incorporates cabinet voicing technology that delivers natural amplified guitar tone when using headphones or recording directly into compatible audio equipment, making silent practice and home recording simple and convenient.
