PRE-OWNED BOSS Katana 100 MK1 Guitar Amplifier

The BOSS Katana 100 MK1: The original tone powerhouse that started it all

Legendary Katana Tone Engine for Electric Guitar Amplification

The original BOSS Katana 100 MK1 combo amp laid the groundwork for a new generation of gig-ready solid-state amplifiers. Celebrated for its punchy 100-watt output and responsive feel, this Mark 1 version offers everything a modern electric guitarist needs, from bedroom practice to live performance. With five amp characters and integrated BOSS effects, it provides versatile sonic possibilities straight out of the box.

Built-In Effects and Deep Control

Take full control of your tone with three independent effect sections: Booster/Mod, Delay/FX, and Reverb—all accessible via dedicated knobs and buttons. The Katana 100 MK1 also includes a comprehensive tone-shaping section with Gain, Volume, and a three-band EQ, as well as a Presence control and selectable Power Control switch that lets you drop the output to as low as 0.5 watts for quiet playing with full tone.

Gig-Ready 1x12 Combo Design

Outfitted with a custom-designed 12-inch Katana speaker and housed in a compact, rugged enclosure, this combo delivers gig-level volume and tonal authority while remaining portable. The amp’s 100-watt solid-state power section ensures high headroom and clarity, even in demanding stage environments.

Connectivity That Works for You

From direct recording to live looping and pedalboard integration, the Katana 100 MK1 has you covered. With dedicated send/return jacks, headphone/recording out, USB connectivity, and compatibility with optional GA-FC foot controller, it's built to be a flexible centerpiece of your rig.

Trusted, Road-Tested Performance

This first-generation Katana remains a favorite among players who value reliability, quality tone, and intuitive design. Whether you're dialing in vintage crunch or a saturated lead tone, the Katana 100 MK1 delivers consistent performance and tonal depth at every volume.
