Katana enters round three

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 50 Gen 3, a new and improved version of one of their most popular models, complete with enhanced features and – just as importantly – still for an extremely attractive price.

Upgrades where it counts

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, users can find inputs for expression pedals, AUX in, headphones, 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.

Serious sounds, modest price

The Katana series continues to grow in both sonic range and versatility. The Gen 3 model of the Katana 50 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 makes tone shaping intuitive, and with switchable output power, the amp mimics the feel and response of a cranked valve combo at lower volumes. Considering the sound quality and sheer capability on offer, calling the Katana 50 Gen 3 a beginner's amp doesn't really feel fair: While it's still beginner-friendly, its performance level is likely to impress even experienced or semi-pro players.

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 punchy 50W power section, and a 12" speaker in a compact combo format, the Katana 50 Gen 3 raises the bar once again for affordable guitar amps. 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 Katana 50 Gen 3 is more than ready, especially when paired with optional footswitches. 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.

Very Pleased

John Cousins 03.02.2025

All my guitars sound great through this, recording using a mic is excellent, even recording straight off the headphone output is better than using effects pedals as preamps. As predominantly a bass player, I used to use my treble guitars through my bass head and a 2 by 12 cab thinking they sound pretty good, but now I realise what I've been missing. I've spent more money on pedals with the effects this combo has ,than I paid for the Boss Katana. Electro acoustic guitars sound pretty good too.

One of the best Solid State Amps

yvaiwhy 06.03.2025

From glassy cleans to sick riff tones this amp has it all. Sure it's 50 Watts but that's 50 Watts plenty enough for practice or a small gig for that matter. The only thing missing on this would be an effects loop which they still reserve for the 100W models for some reason.

I LOVE this amp

Tonkistas 20.04.2025

I got this amp after my old one broke and i got to say its amazing.
For context I have been playing guitar for a year and a half now and my old one was really bad so this is a huge upgrade for me. I love every aspect of the katana from the aesthetics to the range of tones i can achieve with it.
Overall its probably the best amp for beginners with the best value for its money. I totally recommend it!!!
