Description
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.
