Boss Katana Guitar Amplifier Head



Turn your attention to the rear of the amplifier head and you'll notice quite a few connective possibilities. For instance, you'll see the speaker output right alongside the headphones/recording output. This gives you the ability to direct your sound to cabinets, headphones, and recording devices with a minimal amount of maneuvering. Additionally, a line out jack allows you to route line-level signal to mixers and PAs. An effects loop affords you the opportunity to use outboard gear, and an auxiliary input jack lets you play audio from compatible players through the amplifier head. 

But wait, there's more! For external control, there are two different footswitch inputs, one for channel selection/expression pedals, and one specifically tailored to the all-encompassing GA-FC foot controller. Should you wish to control the amplifier through MIDI messaging, you can do so via the dedicated MIDI input.


Built-In Monitor Speaker 
The amp's built-in 5" speaker lets you check tones and practice without having to connect to a cabinet
5 Distinct Amp Characters 
The amp offers five amp characters with tones ranging from organic vintage to modern high gain; Clean is natural and transparent, Crunch offers a small amount of grit, Lead has a wide gain range to suit many styles, Brown delivers a refined high-gain tone, and the Acoustic character provides a tonality geared toward acoustic/electric guitars
Pedalboard Sounds without the Pedalboard 
Via BOSS's Tone Central, you can choose from 55 effects to load 15 different modules into the amp at any one time, using three of them simultaneously; four Tone Settings let you store custom amp and effects setups for instant recall, and you can always jump to the current panel settings at the touch of a button
Extensive Footswitching Possibilities 
External control is possible with multiple inputs for optional footswitches, expression pedals, and MIDI devices, as well as a dedicated input for the GA-FC foot controller
Intuitive Operation 
Dedicated knobs for multiple gain stages, the three-band EQ, and presence control allow you to dial in tones by ear, just as you would with a standard tube amp; essential effects parameters are adjusted with a simple knob twist, and Tone Setting memories can be stored with a brief button hold
Power Control 
A Power Control selector lets you reduce wattage, allowing you to lower the volume for small stages and home-playing without sacrificing tone
Connection Options 
The speaker output allows you to connect to eight or 16 Ohm cabs, while you can also send a simultaneous direct feed to PAs, mixers, and recording interfaces via the line output, which provides the mic'd up tone of the Katana in all of its power, fullness, and dynamics; a dedicated effects loop can also be utilized to loop in outboard gear
Computer Connectivity 
You can send mix-ready sound to your DAW via the USB port, recording directly to your computer without having to take an analog DI
MIDI Input 
A MIDI input jack enables seamless integration with external effects and MIDI switching devices like the BOSS ES-8 and ES-5
Tone Control & Tone Studio 
The Katana gives you access to Tone Central and Tone Studio; Tone Central provides a plethora of free amp and effect setups created by seasoned professionals and downloadable by you, while Tone Studio gives you a convenient way to organize your Katana presets for different gigs, recordings, and practice sessions
