Boss KTN-ART 3Guitar Amplifier with speakers

Fantastic solid state combo amp. I’d buy this again no doubt. If you’re not going tube, get this. It’s that good.

This will be my one and only amp in my life. I have been playing guitar for 60 years and have many amps and MANY pedals. I can now setup on stage easily. I also bought the pedal control for my BOSS. I recently purchased the BOSS bass amp as well. I am now set for life. Great work BOSS.

I believe this is the only amp I will ever need. Excellent tones, amplification, cabinet, and human interface design. Exceptional quality. I believe the Wazacraft 12" speaker is adding do much to the sound.

Très bon produit mais la tonalité générale a été complètement refaite et diffère de la génération précédente (Gen 2). Les sons "Clean" ont à mon goût perdus de leur coffre et de l'attaque chaude que la version MkII avait. C'est une opinion bien subjective. Je joue uniquement en clean et mon avis n'est que pour cette palette.

Apparently I managed to snag one of the few new Katana Gen 3 Artist 100 combos early shipped to Boss retailers - most shops including the large chains are still showing them on pre-order. Have owned/used a Katana MkII 50w for past 2 years for home noodling as an amateur player - have LOVED that amp, amazing # of features and price just made it feel like a steal - and the Boss Tone Studio has also been awesome to build a tone library for all types of music. So why upgrade to 100w, Gen 3 & Artist model? 1). Effects Loop - I wanted to add background tracks/loops to help make playing solo more interesting, and the 50W versions don't have EFX loop like the 100W models, so I don't really need a 100W output, but now I can use the Boss RC-5; 2). New Gen 3 Bluetooth adapter works great and allows me to do 2 things wirelessly with ease - (a) play music directly thru my Katana clean (not thru effects loop) to play along with (or just listen as a speaker), and (b) can use the mobile BTS app to adjust settings. Have only messed briefly with this, but so far the desktop and mobile Boss Tone Studio apps are working fine for me on Macbook Pro and Iphone SE without issues, and I was able to easily transfer my MKII tone patches over to Gen 3. Note the BT adapter is separate and about $60 but easy plug-in. 3). Gen 3 effects add a few more hundred variations to the 1000+ the Katana already offers, lol 4). I bought the Artist model because I watched a lot of A/B comparisons on YouTube and honestly while I like both the standard MKII and Gen 3 tones, figured for +$200, that's the cost gap for the premium Waza speaker alone and I liked the low/high output of Waza, you get some other features and the "experts" basically say while the std. Katanas sound really close to tube amps to most except expert ears, the Gen 3 and Artist tone updates put this amp in realm of popular premium tube amps that cost way more (and someone of my level would never justify paying for). For an amateur player like me who also enjoys building custom guitars, this Katana Gen 3 Artist is way above "all the amp I'll ever need" (even if I gigged someday). The ability to not only create infinite tone patches, but use the Boss Tone Studio and download/share hundreds of free and fee tones, basically allows you to use ONE amp and create or replicate just about any amp/tone you want, which is amazing. Like most other pundits, I think the Boss Katana amp line is one of those rare products that is just a home run in every respect, with tremendous value in $300-600 price range - and they've just improved on it with Gen 3. So far in first few hours using this amp, the only quirk I've found is that when I switch tone patches in Librarian, there's a noticeable 5-8 second lag before the new tone selection goes live thru speaker that I don't encounter with my MKII. Not an issue, just something it does and maybe a future firmware update might address. Great job Boss/Roland - and seller Pitbull for shipping promptly!
