Differences Between The Boss Katana MK1 And MK2
You may already own a Katana MK1 and are just exploring the MK2 to see if it is worth the upgrade. Some changes are only found on the 100-watt version, which is why we reviewed this model. But rest assured, an upgrade to any of the MK2 models will add more to your rig! Here is a quick look at the differences.
The variation button is found throughout the MK2 models and expands on the amount of voicing the Katana has to offer. Once you activate this feature, you are provided a different variation of the 5 already well known presets.
You could essentially consider these 10 voicing to play with, up from only 5 on the MK1.
On the MK1, the number of effects that could be used simultaneously was 3.
But on the MK2 they have increased that to 5! Not only that, but they have also included more effects on top of that! MK1 was 55 effects total, but the MK2 has 60 effects to offer.
Power Amp IN
Another new option on all MK2 models is the power amp IN jack. This jack allows you to bypass the Katana preamp and run an input directly into the power map on the Katana.
This can be handy if you want top run another modeler, preamp or amp simulator into the power amp.
This is a new option exclusive to the 100 watt version. This option allows you to connect two 100 Watt Katana amps together and run them in true stereo.
Talk about a powerful rig!
The Boss Tone Studio editor has also undergone some changes.
The interface has been changed for a fresh look and feel, and some parameters have been moved around to make it more convenient when editing.
Boss Katana MK2 External Hardware
The Katana 100 MK2 weighs 33 Lbs and measures 21″ wide, 17.5″ high, and 10″ deep. It is equipped with 1-12″ speaker in an open back wooden enclosure finished with black tolex and corners.
The controls are available from the top of the amplifier for easy access and feature a modern look. If you are familiar with the MK1 version of the Boss Katana, nothing is really that different. The Amplifier looks exactly the same except for the front logo and some added controls and jacks.
The handle is mounted more or less in the center, making the amp easy to carry. Grill cloth on the amp is a standard knit that is found on a lot of amplifiers, but looks great on the Katana. Over all, the amplifier is well-made and still looks great in the MK2 series
Boss Katana MK2 Channels and Controls
The Boss Katana MK2 still has a familiar control scheme which is intuitive and easy to use. The preamp provides 5 different amp voices: great clean, crunch, brown and lead plus an acoustic setting. But what’s really cool is the MK2 version now features a variation control!
This provides a different variation of each of the 5 voicing, essentially making these 10 different sounds!
The MK2 version comes with the ability to choose from over 60 built-in Boss effects using the dedicated software. But not only is that amazing, Boss has gone ahead and provided the ability to use 5 of them at the same time, up from 3 on the MK1.
The controls for the effects are also different in the sense that the knobs are far easier to use and selecting effects is so much easier than the MK1.
On the rear of the amplifier, you will find the headphone output, aux In, effects loop and foot switch jacks that you are probably familiar with. Boss has now added some new features on the 100 watt version.
It is called stereo expand and allows you to connect two boss Katana MK2 amps together and run them in stereo! And if that isn’t already super cool, they have also added a power amp in jack to allow you to run any preamp or modeler into the Katana Power amp.
The Boss Katana MK2 is very powerful with 100 watts of output! Playing the amp in a live band setting, we were easily able to keep up with a hard hitting drummer.
So don’t worry about volume, the Katana 100 will do what you need and then some, just like the MK1!
The amplifier also has a variable power switch to allow you to cut the power down to 50 watts or .5W for quiet use.
If you prefer the 50 watt model, there is also one available.
Boss Tone Studio
The Boss Tone studio software has also had some changes. The interface has been updated, some parameters have been moved to the main screen for more convenience.
There is also a dedicated pedal FX category!
Selecting your effects, channel EQ, setting up effects, channel presets, it’s all possible with the new Tone Studio.
Customizing your sound is super easy! And if you have patches from an MK1, you can import and use them on the MK2!
The effects loop on the Katana 100 works very well. We ran some standard modulation type effects in the loop and were pleased overall.
The Loop is buffered and so there did not seem to be any loss of quality in the sound. The effects loop is found after the preamp but before the onboard effects in the circuit.
But rest assured, you can use pedals into the effects loop with the built-in effects at the same time.
Boss Katana 100 MKII Sound
The first version of the Katana was a home run for boss from a sound perspective. There were some sounds that could have been better, but it was a great amp for the money!
Boss has improved it all and provided more! The MK2 is an excellent amp! With the improved sounds, the added effects and the improved software, you really cannot afford to go another day without one!
The sound of each of the voices has been improved, they really made the amp sound more like a tube amp than the first version. The feel of the amp is also changed and seems less digital and maybe more analog, but I don’t have an MK1 here to test it up against to be sure.
What I am sure about, however, is that this is a superb upgrade when compared to the MK1!
For an amplifier under $500, the effects sound great! Overall, I am pretty impressed with the way this amp sounds and feels, it truly is a powerful tool.
If you own an MK1, you will want to try this amp, just be prepared because you are probably going to want to upgrade!
If you are looking for an amplifier in the under $500 category, there is a lot to choose from. But we were very impressed with the Katana MK2! It sounded pretty good as soon as we jumped in and started using it. Even before tweaking the EQ a bunch.
Now, if you have some high-end amps, well you might not be knocked out of your seat. But it’s awesome for beginners, and its sounds are somewhere between fantastic and great.
If you are in the market for a Swiss army knife type amplifier, you probably found it.
Boss also makes a 50 watt version of the Katana which you might also like, however it does not come with an effects loop and the 100 watt version comes with a 50 watt setting for only a few extra dollars, which is more bang for your hard-earned buck.
It might make more sense to just go big or go home with the Katana and just grab the 100 watt version.
Both the Katana MK1 and MK2 are great amps. The addition of a few more sounds and features does make the upgrade worth it.
It’s also got tons of power and some great versatility. Plus, it will serve many needs of players today that it is a hard one to pass on for the price. We enjoyed the amp and rate this one quite high for this price point!
