Boss Katana Head Gen 3, modelling head for electric guitar

Since their debut in 2016, Katana amps have become some of the most successful guitar amplifiers on the market. With a smart range of power options, compact dimensions, and a generous collection of built-in sounds and effects, they strike a perfect balance for today's players, offering professional sound in a portable format. After all, nobody wants to lug around more gear than necessary. Add to that their wallet-friendly price point, and it's easy to see why the Katana series continues to be such a hit. Now, Boss has introduced the Katana Head Gen 3, a new and improved version of their phenomenally flexible modelling head, complete with enhanced features and – just as importantly – still for an extremely attractive price.

An infinitely flexible Katana

Boss has refined its Tube Logic engine to deliver even more authentic amp tones. One standout addition is the new "Pushed" amp type, designed to emulate the raw, dynamic edge of a valve amp being driven hard. Like the other amp models, it's available in two voicings. The effects section remains split into five blocks, offering the usual high-quality selection. Delay times and modulation effects can be tapped in by hand or controlled via an external footswitch or pedalboard. Around the back, alongside the main speaker out, users can find inputs for expression pedals, AUX in, headphones, FX loop, MIDI in, and USB for direct recording. New to Gen 3 is a slot for an optional Bluetooth adapter, which is ideal for wireless audio streaming or remote control via the Tone Studio app.

A head full of dreams

The Katana series continues to grow in both sonic range and versatility. The third generation of the Katana Head offers a broad spectrum of amp and effect combinations, ranging from acoustic presets and sparkling cleans to rich crunch and soaring modern leads. The responsive three-band EQ, with dedicated contour controls, makes it easy to shape the sound to whichever guitar or speaker is currently in use; and with adjustable output power, a presence control, and switchable cab resonance, the head can reproduce almost any sound a musician can dream of. But they won't have to dream it – thanks to the integrated 5" speaker, it's possible to have plenty of fun with the Boss Katana Head Gen 3 even when there's no full-size cab to hand.

About Boss

The Boss brand has been an important part of the Japanese Roland Corporation since the mid-1970s and has caused a sensation from its inception, especially with its compact effect pedals but also multi-effect units and other helpful tools for guitarists. The company's single effect pedals in particular are legendary and can be found in almost every guitarist's home. An incredible 15 million have been sold to date. With its Katana series, the manufacturer now also offers excellent amplifiers at a very interesting price point.

A versatile third-gen powerhouse

With a wide array of amp tones and effects, a generous 100W output, and its phenomenal range of features, the Boss Katana Head Gen 3 raises the bar once again – other heads can head home. Thanks to the integrated 5" speaker, it's as comfortable in a living room session as it is in rehearsal spaces or recording studios, thanks to the USB output that allows for direct, high-quality capture with spacious tone. And when it's time to take it on stage, the third-gen Head will be ready, when paired with a suitable speaker, of course. To top it off, the Boss Tone Studio app provides deep editing tools in a clean, intuitive interface, and now, with the optional Bluetooth adaptor, users can tweak their sound wirelessly from their smartphone or tablet.

Perfect companion for home playing and beyond

zngrn 15.06.2025

After selling my tube amps, I was on the lookout for an amp which could primarily take care of a few things for me.
1. Decent headphones out option
2. Sound close enough to a tube amp even if it wouldn’t be able to replicate it’s dynamic sounds completely.
3. Have a FX loop
4. Attenuation friendly for silent play in an apartment.

I ordered this hoping I would be fine with the small 5” speaker.

After trying the pushed and crunch channels I was convinced. It’s still early days but I’ve played some blues rock and also plugged in my pedals. Works like a charm, small enough in size and sounds really good.

At first I was torn, on wether to pickup a tube amp maybe, then I went with this amp instead.
Gen 3 sounds amazing out of the box, no need to even go dialing in the tones, just plug it in and it's perfect. I went with Harley Benton 2x12 cabinet and I'm just amazed at what this combination can do. I've seen a lot of positive reviews, but in person, it's something else.

Can’t go wrong

Had the old mk2 50w an amp that blew me away, this one I’d say is about the same, it has more features and more holes at the back, got surprised at the type-c cable at the back because i didn’t pay attention when ordering but it’s ok. Overall I recommend it.

Ein Alleskönner

Frusciante Fan 19.08.2024

Ich habe mir lange überlegt, welchen der Amps aus der Reihe Gen 3 ich mir zulegen soll. Sollte ich noch auf den release der Artist Reihe warten? Letztendlich haben mich jedoch diverse Youtube Videos u.a. von den studio rats oder Dave Simpson überzeugt, mir den Boss Katna Head zu kaufen. Zu recht!
Der Amp ist ein wahrer Alleskönner, mit dem neuen pushed channel können nun auch die leicht angezerrten Sounds a la Hendrix produziert werden (natürlich am besten mit einer strat ;)). Speziell der Head kann auch alleine ohne cabinet verwendet werden und klingt mit der richtigen Lautstärke auch sehr solide und lässt sich hervorragend als Übungsamp benutzen.
Aber um den optimalen Klang zu erzeugen sollte er natürlich in Kombination mit einer guten Lautsprecherbox verwendet werden.
Für mich sind vor allem der clean channel und der pushed channel wichtig, diese haben meine Erwartungen voll und ganz erfüllt, für diesen Preis also eine absolute Kaufempfehlung von meiner Seite.
