Wow… I was not expecting this video to be THAT popular! Thanks for the support guys, follow up video coming on Sat with an interesting result🤘🏽

Everyone knows the more dust you have on your Katana the better the tone

[RandyWillcox]

Yes! The 100W setting with the cranked master is that "real amp" sound people think modelers can't achieve.

[stefromfortworth]

The answer is YES and I heard from a mate who works in a guitar shop…..who heard from a Boss rep that the amp is specifically designed to fatten up and compress a little bit like a vale amp when ran at full master volume (using the channel volume to set your level)

I run mine at 0.5w with the master volume on full and then set the volume I want with the channel volume. It’s awesome.

As an owner and operator of the Boss 100 Mk1 I cannot say enough about how fantastic this amp and line is. While its packed with built in tones as Rob demonstrates, I also love running my pedals thru the clean channel and my looper thru the FX Loop. Pure Rock Bliss. Thing launched in 2016 and we are still talking about it. If you don't have one then give in and GET IT!!!! :)

I have an interesting update to follow this video soon. Having had a really good chat with Boss! 🤘🏽

I just can't get over how good that amp sounds

[horrifyinggelatinousblob]

The Katana is amazing, seriously even if you don't NEED an amp, if you can afford one go for it, you won't regret it.

[mikebarrett]

You are spot on Rob, I heard the difference straight away! It sounds more powerful even though the volume is the same. Sorry it took so long to find your video .

Hey Rob. I'm an old gigging musician that has always used tube amps live. I bought a Katana 100w a few months back for smaller gigs and to check it out. I was initially underwhelmed and it sat in a corner doing nothing. To be fair, I did not invest time in the custom configuration capability. With all that said - the term Hack is overused - THIS is a hack. So much rock. I will be gigging this with the gunned master this Friday.

The 50watt option is the goat on this amp

[valuedhumanoid]

I have had my 100 MkII now since Christmas and got the foot controller last week. Got a great deal because it was a floor demo and the controller was a scratch/dent special. The only gig I do is an open mic night at my local club every other Thursday. I do a 3 song set where I play over a backing track. This amp is perfect for things like that. I know when I plug it in and hit the power switch, it's going to work. And it is easy to move. But the more I use it and play around with the settings, I find new little Easter Eggs I never thought of before. Rob is right, the power settings influence all the tones and depending on your guitar, you can get real close to what we would all call the Holy Grail sounds of our favorite records. That's a feat that many modelers strive towards, not many make the cut.

I practice all the time with my Mini on the brown setting. I personally love that Boss Brown sound. Whatever you did kicked it up a notch for sure.

I've noticed that about the Katana when I play through it. It responds very similarly to a true tube amp when you dial back your volume knob on the guitar. You can have full distortion and dial it all the way down to almost completely clean without switching channels. The overdrive on this thing is amazing because it responds so well to volume and tone adjustments on the guitar. My old Line 6 Bogner tube amp had amazing heavy distortion tone but it didn't matter what you did with the guitar. It basically put out the same amount of crunch no matter what with only minor differences even between pickup changes. I'm blown away by this thing with no tubes. It's still not quite as silky as a true tube amp, but it's so close I don't really care for tooling around in the bedroom. If I was laying down tracks in a recording studio I might get silly about the tone again, but even then, the line out on this amp sounds even better than it does through its own power amp, so I might not care even then.

Hi Rob! I think 2 things are at play here. The first thing is compression. If the amp section is designed to be wide open and the overall volume depends on how much signal you give it you may have more compression at lower volume due to padding the pre-amp's output down to mimic less wattage. At the higher setting less of this type of compression takes place and more harmonics can be heard as a result. The other thing is damping. If you have more power to move the speaker, you also have more power to stop the speaker from moving. Basically you have more control of transients and thus more low level detail is audible and you have more bandwidth in terms of frequencies. The result is that the amp might sort of sound like a class A amp at 50watts and a class A/B amp at 100watts even tho from the standpoint of the actual electronics it's either one or the other, more than likely class A/B. Since Marshall amps are class A/B it makes sense that it would sound more "Marshallesque" in the 100watt setting.

[leightnite]

I believe your right Rob! To me it sounds better, there's a big midshift it sounds like, the regular mode feels inherently more scooped!

[trex]

I have done the same thing on my 100 watt katana, it is why I bought the amp. When I first played it in the guitar store, it sounded incredible for a solid-state amp. When I got home, I couldn’t figure out why I didn’t sound the same until I turned on the 100W mode and upped the master. Suddenly, it sounded far better than my other, real tube amp. You definitely are not crazy.

Hi Rob!
Been doing this ever since I got my Katana Artist. The Master on full gives it a more tube like feel and sound. And I got the tip from the first Video Andertons did at Namm, when the MKII Katana came out. I think it was Pete and Lee who made the demo and they were told by Boss to crank the Master.
Cheers

On my Katana Artist, I like to add a Boss Compression Sustainer pedal between the guitar and the amp. I use my guitar volume knob to control the level of articulation and definition of the sound. With the amp cranked and volume knob set to 10 on the guitar, you'll get the result of a guitar where you hear every note in its clarity of attack like when you hit the keys on the piano with no effects or sustain to it, just like in this video demonstration. When I roll the volume knob on the guitar down to 1.5 to 2 on the knob, you'll get this amazing breathing, sustain coming out of the amp. It sounds like its pushing the "valves" harder and is opening it up further with sustain. When you barely have the guitar volume knob set on between .5 to 1 you get a clean sound with just the right added slight dirty distortion with again the feeling of the amp breathing with using the added compression sustainer pedal. The other benefit, is ease of use for the player. Makes the guitar more responsive and sensitive to the touch for the guitar player. For me, I get more interaction out of my guitar by doing this method and come up with some amazing results.

man, that sounds pretty convincing, even through desktop speakers with my laptop. I'm thinking that amp is going to be my next one, and I already have a Marshall JCM 2000 DSL-100 with a 4/12 cab. Most definitely a very nice sound you're getting there.
