Option paralysis + a "digital something" made me say Sayonara to the Katana
Chief_Greco, 14.02.2019
So i bought into the Katana hype after watching far more YouTube videos than id like to admit to. I have a Marshall avt 100 practice amp that I've grown very bored of and thought i'd get away replacing a +500 euro amp with limited features, with a 300 euro amp that DOES ABSOLUTELY EVERYTHING!!! . I know, i know.. Bad logic.

I bought the 1x100 combo even though a big part of me KNOWS FOR A FACT that you always get what you pay for in ALL areas of life. Its a rule of life everyone should follow, until death.. The sooner you learn it, the better. The Boss Katana once again, set this fact into stone for me.

So what can you expect out of a 300 Euro Swiss army ss/digital modeling amp? You get a lot of decent tones and effects, but its certain to me that everything falls quite short..

I tried most of the Katana's overdrive, tone booster, fuzz pedals, distortions, amp sims EQ's via boss's tone studio, and to me, they all sounded digital at their core. Especially with anything distorted.. There's just something missing from the sound. And i didn't detect what i heard in person, through ANY YouTube video.

For clean playing, or slightly dirty, i found this amp to play much better. The tone boosters are pretty cool and the tones you get can be quite nice. But there's always that split second within your jam, when you'll stop and say "this sounds kind of off". And that's where my biggest issue with this amp was...

I ended up spending hours tweaking tones in the boss editor, searching through "sneaky amps" and tone settings i found off Katana tone sharing forums, saving my 8 presets and replacing effects with ones i liked. The funny thing was i thought i was done, so i unplugged my USB cable (which Boss doesn't supply) from the amp, turned it off and went to bed.

Problem was, I'd wake up the next day, run to my amp (without even brushing my teeth) only to hear the tones i preset the previous night, didn't sound nearly as good today.... Back to the old drawing board i said to myself!! (Boss tone studio).. Out comes the USB again.. With my sweet Fender Stratocaster with fat 50's pickups on my lap and in one hand, and my Hewlett Packard mouse in the other hand... Strumming and click, click, clicking away for hours.... Set my tones again, and saved them.. This time i did it right, i thought.. Gonna be rocking non stop tomorrow with these sweet tones. Go to bed..

Wake up the next day, chug a coffee and run to my amp. What?!?! This sounds nothing like i thought it did last night? Why?? How?? Whats going on!! Let me play guitar you crazy bipolar amp!!

This went on for nearly 3 solid weeks my friends, until i decided to return the amp before i lost any more hair due to the stress it was giving me.

*** Very important facts about the amp that no one will tell you is that every channel has a drastically different volume. (Clean, Crunch, Lead and Brown) So you cant switch between channels on a preset without adjusting the volume. The clean channel is by far the lowest in volume and i very much doubt that its even 100 watt on the clean channel.

Its not a 300 euro amp, because without the Boss pedal (sold separately) , its not very fun. You simply need the foot switch. Period. So Its a 400 euro amp really.

Another very big one, is that this amp sound very bad at bedroom levels. All the digital qualities jump out much more when its very low. Reverb fades out almost into a digital scramble. Admittedly the amp sounds much better at higher volumes. But I found the 0.5 mode not useful at all for low volumes. Its basically useless and can get very loud even at 0.5.

To sum it up...

All in all, this amp is great for beginners. It will give them all sorts of sounds and effects to play around with. It will teach them what effects they like and so on. But if you've been playing for more than 10 years (25 years in my case) and know better gear, don't be cheap like i was. You will be let down. Get a good pure SS like the peavey bandit, Orange cr or a Fender champion 2x12. Buy the pedals you like and enjoy real tone. Even go tube if you have the cash for it.

Probably the biggest factor of disappointment was the whole "digital feel" of this amp. Using my mouse in conjunction with my amp and guitar is something i want nothing to do with ever again and even made it feel and sound MORE digital. These things really matter on an emotional/creative level. You think they wont, but they will. This isn't the way the greats made true rock music, and i believe if they had to use a mouse and a computer to adjust their tones, we would have FAR LESS cool music to look back upon today.. I truly believe this to be a fact. This part of the amp truly robbed me of any inspiration. And that was the last draw for me. The katana didn't cut it for me, and I had to send it back.

Always remember... You always get what you pay for.. And more isn't always better..

Rock on, fellas.

Absolutely fantastic !
TeoD, 06.07.2017
I bought this as I got tired of using my Line 6 Spider IV 15 because of the limited tonal possibilites and the somewhat inferior quality of the tone put out.
Out of the box, I could get any tone I want. From an overdriven SRV sound to high gain metal to crystal clear cleans, this amp does it all ! The effects it comes with are really useful (especially that amazing reverb) and configuring them on the panel is very easy. The true wow-factor comes out when you connect it to a computer and start changing absolutely everything. You can tweak it to no limit. You can change the effects you have on each channel (including the panel) and you can also change their parameters (just like on a high end pedal). You can tweak the start time of the reverb of your choice, you can configure a compressor... it's like having an amp and 58 pedals, all in one ! Not to mention that I've never had to accomplish an easier task than that of updating the firmware on this amp. It literally takes under a minute and anyone could do this. Haven't had this much fun with an amp in a long time. Even though it's solid state, it can produce a lot of tasty tones (and very varied, at that!)
I would recommend this amp to anyone who's looking for a decent priced amp with TONS of features and a great sound for any musical genre. Versatility like this is a huge bonus in any circumstance !
