This is an open box unit of the Boss Katana-Head, a 100-watt solid-state head engineered to punch well above its compact size. Drawing on tech developed for Boss’s flagship Waza amp, the Katana-Head is tuned to interact tightly with your cab so notes stay defined and present even under heavy gain or high volume.

Five amp characters: Clean, Crunch, Lead, Brown (Waza-derived high gain), and Acoustic for acoustic-electric guitars
55 built-in effects via free Boss Tone Studio software, with 15 loadable at once and up to 3 running simultaneously
Four Tone Setting memories for instant recall of full amp and effects configurations
Built-in 5-inch monitor speaker for silent-ish practice without hooking up a cabinet
Power Control with Standby mode for scaling tone from stage to bedroom without losing feel
Effects loop and MIDI In for integration with external pedals or MIDI switchers like the ES-8/ES-5
Line Out and USB for mic’d-up direct tone to a PA, interface, or DAW
Speaker output rated for 8-ohm or 16-ohm cabinets

Everything you’d tweak on a tube head — gain stages, three-band EQ, presence — is available on dedicated knobs, so dialing tone by ear is fast and intuitive despite the deep feature set underneath. Whether you’re loading a stage cab for a full show or just running direct into a DAW, this head covers the ground between vintage clean and modern high gain without needing a pedalboard.

Note: this unit is sold as open box — fully functional, previously opened stock.
