About Boss Katana-Head MkII

Let the Boss Katana-Head MkII 100W 1x5" Guitar Amplifier Head elevate your musical performance to new heights. This powerful and versatile amplifier head, known for its high-quality sound and durable construction, is a product of Boss, a brand renowned for its reliable musical equipment.

The Katana-Head MkII is a solid-state amplifier head with a robust wattage range of 100W to 250W, making it suitable for a wide range of musical genres and playing styles. It features four channels, providing you with the flexibility to craft your unique sound.

This amplifier head is not just about power; it's also about versatility. It comes with five primary amp characters that offer everything from organic vintage tones to modern high-gain sounds. Additionally, it includes a dedicated voice optimized for acoustic-electric guitar. The characters have been extended with newly voiced variations, providing a broader palette of tone options for you to explore.

The Katana-Head MkII also 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.

Backed by Boss's Tube Logic approach, the Katana-Head MkII delivers the authentic output distortion characteristics of genuine tube amplifiers. The sound and feel become richer and more responsive as you turn up the volume. However, unlike traditional tube amps, the Katana-Head MkII's variable Power Control allows you to enjoy inspiring, cranked-amp sound anywhere you play, from bedroom to stage.

The Katana-Head MkII is also versatile enough to serve as a dedicated amplifier for your favorite preamp, modeler, or multi-effects unit. Connecting to the rear-panel Power Amp In jack bypasses the Katana-Head MkII's preamp and effects, letting you tap straight into the Tube Logic power section.

One of the most powerful features of the Katana-Head MkII is the ability to store favorite amp character and effects setups in Tone Setting memories for instant recall. Eight Tone Settings are available, with fast selection right from the panel.

The speaker out on the Katana-Head MkII supports connection to your preferred 8-ohm or 16-ohm cabinet. Advanced players will appreciate the MIDI input, which provides easy integration with MIDI controllers and switching devices.

The Katana-Head MkII also features line, USB, and phones/recording outputs with mic'd cabinet emulation, letting you send mix-ready amp tones to a PA system, computer DAW, or headphones. The direct sound can be shaped with three different Air Feel settings, which are accessible from BOSS Tone Studio.

Whether you're a seasoned musician or new to the scene, the Boss Katana-Head MkII 100W 1x5" Guitar Amplifier Head is designed to deliver sound, feel, and versatility that soars far beyond its price class. Experience the power and versatility of this amplifier head and let your music take flight.
