The total package in one compact head

The second generation of Boss’s Katana amplifier series delivers outstanding tonal flexibility in both head and combo formats – proving once again that the iconic effect pedal manufacturer also knows how to make a great amp. In addition to its excellent basic sounds, the Boss Katana 100 MKII head also boasts a range of onboard effects and an adjustable power stage output, so a rich-sounding tone is ensured at all times, and players can store their favourite settings to eight different memory patches (two banks of four each). All of this makes the Katana 100 MKII head the ideal partner, whether you’re practising at home, rehearsing with a band, or performing on stage. And there is one thing that cannot be denied: This amp delivers the quality of sound that one would expect only at a much higher price point.

Down to the last detail

The Boss Katana is a typical 100-watt modelling amplifier head, but it can do a lot more than can be expected from conventional amps. Luckily, the Katana’s wealth of features is easy to navigate using the top-mounted control panel or the Boss Tone Studio Editor (available free of charge from, a very practical tool which allows players to fine-tune their settings down to the last detail. And leaving aside the amplifier’s immense flexibility, the range of options available to shape its outstanding sounds to suit your individual taste also make it great for recording, which is made all the easier by its integrated USB output.

Perfect for beginners, that first band, and more

Until just a few years ago, getting your hands on an amp of this quality meant spending a lot more money. However, since the Katana 100 MKII gives players a truly sophisticated amp head at a budget-friendly price, it would also be inaccurate to refer to it as a “beginner’s amplifier”. Or to put it another way: Its price and format are perfect for taking your first steps on the guitar or in a band, but its quality goes far beyond that, making it equally interesting for experienced guitarists who are searching for an amp that sounds good even when playing quietly at home, are reluctant to spend more money than they have to, or simply wish to avoid having to get to grips with overly complicated technology.

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.

Your personal custom amplifier

True, the Boss Katana 100 MKII head can do a lot. But what it does best is to deliver exactly the sound you want, when you want it – precisely what guitarists need and desire. Hundreds of different options are of course nice to have (and the Katana 100 MKII offers a great many), but ultimately, the decisive factor is how easy the amp is to use, how precisely players can customise their sounds, and of course whether the end result sounds great. That is where the Boss Katana comes into its own: With fewer than 20 controls and buttons, it has everything guitarists need to find the perfect sounds to suit their guitar and their playing style – from crystal cleans to full-throttle drive sounds – in next to no time.

A great all-in-one feature-set with one detail missing
Press K 02.07.2020
I won't tease you — the detail missing is a tuner. I was kind of blinded by the massive amount of features and forgot to check if the amp had a built-in tuner, but oh well — it is what it is.

It sounds very good for home practice, band rehearsal, and even a live gig. The flexibility with the speaker out is just insane. In my opinion, its sound is not very convincingly "natural" but it can definitely get close when paired with a good guitar cab and thrown into a band mix. And yes, it can cut its path in a band mix.

However, you do need to adjust settings between those scenarios and this is where the Katana falls flat a bit. You only get to save a few presets. And, when you are in a specific preset, you can't know where exactly your EQ pots are dialed in, so rotating one of them makes your settings jump to an extremely different location.

What I am saying is, it needed LED markers around the pots to show you exactly what each setting is dialed at.

Putting aside the woes of editing your presets on the fly, this little amp is a true champ for the bedroom musician who gets to gig only occasionally. Without breaking the bank, you get a quiet practice amp and a live amp with integrated effects, all in one.


Hard to Beat

Musicians often have to make compromises. With Boss Katana, the word "compromise" becomes useless. It is well known that tube amplifiers are the "holy grail" for guitarists, which they are for a reason. With this product, that "holy grail" or at least a large part of it, is available to many who will enjoy the great guitar tone and the countless possibilities it offers. The highest possible recommendation for the Boss Katana Head mk2.

Bester Amp in seiner Preisklasse!

Verwende den Amp zur Probe und Live.

Wir spielen modernen Metal und der Boss ist (in kombination mit dem Boss 212 Cabinet) ein echtes Biest!

Die Watt sind in Röhrenwatt gerechnet, das reicht für jede Bühne und jeden Proberaum!

Die Bedienung am Gerät selbst ist gut, aber wirklich übersichtlich wirds dann doch eher am Rechner per USB. Die kostenlose Software lässt dann das wahre Potential des Amps erkennen.

Alle Pedale, die es von Boss so gibt hat der Kasten integriert. Also genug Raum für coole Effekte.

Mit dem Fußschalter lassen sich dann auf (quasi) 8 Banks Sounds speichern und schnell abrufen.

Mit dem kleinen, im Top integrierten Lautsprecher ist der auch Wohnzimmer geeignet. Ich überlege mir derzeit, einen zweiten für daheim anzuschaffen. Dann hätte man die selben Sounds auch zuhause und ein Backup, falls mal etwas mit dem Haupt Amp sein sollte. Ohne Reich zu sein, kann man sich das tatsächlich überlegen, da der Preis einfach stimmt.

Hier hat man alles in einer Kiste, und das war mir am wichtigsten. Ich will keine Pedalboards und zig Extrateile schleppen. Auch der Amp an sich ist bequem mit einer Hand tragbar. Das macht ihn zum idealen Touringamp. Als einziges fehlt ein integriertes Stimmgerät - das Sitzt bei mir noch obendrauf. (Hätte Boss wohl auch nicht umgebracht) :D

Auch die Auswahl an Sounds ist vollkommen ausreichend: Denn mal ehrlich, was brauche ich wirklich alles? Einen coolen Clean Sound, einen tighten Rhythmus Sound, einen singenden Lead Sound und ggf noch Crunsh oder ein abgespacedes setting. Dafür brauche ich keinen Ampmoddler, der mir 3000 tones liefert. Ich brauche 8 die gut klingen.

All das kann der Katana!
