TL;DR - Katana Artist, praised for its Waza speaker, sounds better (to me) thru another, cheaper speaker. Details below.
Katana Artist comes with the Waza G12W speaker, which is Boss's take on Celestion Greenback. I can confirm that, at least for my ears, that speaker makes all the difference compared to the regular Katanas (50/100, had them all), so much so that the Artist might as well be a separate amp. Many reviews and forum posts confirm that as well. Artist can get really close to those sweet tube amp sounds.
I have been playing my lowly Monoprice 15W tube amp more lately and (especially after breaking the speaker in) it sounds really good; much better (more clear and natural) than my Katana. Then I started doing the stupid thing we all do - can I dial my Katana Artist in to sound like the Monoprice? I can get really close using the global EQ available with the Katana. However, there's always those shrill highs that if you tone them down to where they are not annoying you lose the high-end sparkle and clarity. I played for hours and days with all the knobs and settings both on the amp and in the Tone Studio and I get close but as soon as I plug in to the Monoprice I can hear how much clearer and more defined everything is. After getting tired of all that I just made my peace with it - "it's the tube amp thing that SS/digital will never get right". Then, just for the heck of it, I connected the Katana to the speaker in Monoprice. Holy crap! That's it! The clarity, the sweet top end; bright but not shrill, the breakup and distortion are so much more natural... So I've been playing my Katana thru the Monoprice speaker.
Now I can get the Katana to sound virtually indistinguishable from the Monoprice.
Now, that whole exercise got me thinking - Waza is really a well regarded speaker and the Celestion Seventy 80 that's in the Monoprice is always shunned as the cheap entry level speaker. I started reading about the Seventy 80 and the consensus seems to be that it's basically as neutral a guitar speaker as they come (and therefore for many "blah"). That got me thinking some more - Katana uses a DSP to generates its sounds so it's all artificial (the breakup characteristics, etc.). That does not mean it has to sound bad but... it has to be reproduced faithfully. For that you would probably want as neutral a speaker as you can get away with in a guitar amp, otherwise the speaker will color the sound with its own characteristics. So Boss stuck a guitar speaker with its own tonal characteristics (basically a Greenback) to faithfully reproduce the DSP generated sounds? I am not a sound engineer or anything close to that; I am just a dude chasing tone, lol. But to me that does not seem like the greatest decision.
Don't get me wrong, I still believe Katana Artist is one of the best amps of that type you can get. I just think they did not pair it with the best speaker. It seems weird because that speaker is touted as the best part of that amp. I am curious what you think about this and if this make any sense to you.
In the meantime I'll keep playing Katana thru my "Monoprice speaker cab" for now and probably start looking for a replacement speaker for the Katana
