Boss Katana MKII vs Boss Katana 3: What You Need To Know…

boss katana 3 what to expect (1)

What’s the difference between the Boss Katana MKII and the Boss Katana 3? Should you go for the new model or save some cash an get the MKII? Let’s investigate…


Rather than bore your pants off with a long-winded intro that’ll make you bounce back to Google faster than it takes to say, “sweaty muffins” – let’s do something different.

I own the Katana MKII. I bought one as soon as it dropped. I use it every day for practice, recording, and lessons.

So when the Katana 3 landed, I did something unusual:

I reviewed it from a dual-perspective: 1) as someone that currently owns the Katana MKII and 2) as someone that doesn’t.

Why? Because it’s a confusing release. Nothing was wrong with the MKII. But the Katana 3 is great. It confused the hell outta me, so I decided – rather than schilling for clicks – to just do it as honestly as I could.

Here’s my conclusion:

Should you upgrade if you use the previous Katana (MKII) as much as someone like me? I honestly cannot answer that question for you. However, I will not be upgrading unless my current Katana dies.

I suppose a lot of guitarists will agree with me about upgrading. There are plenty of reasons to continue using your MKII version. Just because something is “new and improved” does not mean what you have is now useless.

I still use my Line 6 POD HD from 12 years ago! The effects and amp models still sound great for certain applications. It is just another resource for me to shape my sound.

The Katana Gen 3 does offer a lot to newcomers. If you have never owned any of the Katana amplifier range, then now is the time to try it out! I think this is what BOSS was going for with the Gen 3, new guitarists.

Cool, now we’ve got that outta the way, let’s explore what’s actually different between these two amps.

As you’ll realise below, the Katana 3 does have something of an edge over the Katana MKII when it comes to certain features and capabilities.

But there’s nothing that I’d call a deal-breaker (or something that’d force me to upgrade from the MKII).

Bottom line? If you already own the MKII, save your money – that amp is perfect. The Katana 3 is nice but it is not worth the upgrade; it just doesn’t do enough to warrant replacing your perfectly good MKII amp.

If you’ve never owned a Katana amp and are looking to get one, the Katana 3 is the one to go for – it has everything the MKII does (bar Sneaky Amps) and a whole load more besides.

Here’s how the two amps stack up in a side-by-side comparison…

How Much Is The MKII Compared To The Boss Katana 3?

Katana Gen 3

Newer is always more expensive. Your mom told you that way back when, and the rule applies here.

The Boss Katana 3 costs more than the MKII (which Guitar Center are basically giving away right now). And the reason it costs more? Again, it’s newer but it also has some additional capabilities and features.

So, the way I see it, you have two choices:

  • First, you’re new to Katana, you want the best, and you don’t mind investing: get the Katana 3
  • Second, you’re new to Katana but you want to spend a little less and still get a kick ass amp that is good enough for crusty ol’ pros like myself: get the Boss Katana MKII.

And that’s literally it; they’re both great. I’d get the Katana 3 if my MKII broke tomorrow. But for anyone that’s watching their finances, the MKII is cheaper and it’ll do literally everything you’ll ever need.
