Boss Katana 100 Gen 3 100W Combo Guitar Amplifier

Additional comment having reviewed this over a year and a half ago in July 2024 - I like this amp even more now than then. Really can't find serious fault in the options. Whatever I've needed it to do, it's done it. Blues, metal, pop, country, it has a very cleverly chosen set of amps, especially now they have the Pushed type in Gen3. You could maybe ask for more presets, but with the ability to save and load a full set of 8 in one go, having multiple sets is surprisingly practical.
I have added two switches and an expression pedal (plugged into the extra socket in the back of the amp) to the GA-FC I bought with it - one for solo boost, the other switch to change the expression from volume to wah in most presets, but a couple the expression pedal does more wacky FX control! Clean, Pushed and Brown are the 3 favourite amp types without doubt. Occasionally use the Crunch one too. The simulated Line Out helps to make live gigs a breeze.

Boss Katana 100 Gen 3 100W Combo Guitar Amplifier

Very pleasing and practical amp for band work. Purchased as an alternative to a 15w valve amp and pedals (suits country, blues & Rock n roll), it delivers a different feel and suits different guitars. Marginally, I prefer it with my two humbucker ESP that has series/parallel switching (parallel sounding similar to single coils) when compared with my Fender Strat or Tele, mainly because the high gain sounds like the Brown amp really sing with a humbucker.
The new 'Pushed' amp choice in the Gen 3 amps is great for blues and soul in particular, creating a sound very responsive to your playing. I had my ESP pickups in parallel (single coil type sound) and loved it!
As well as having 8 patches saved in the amp itself (two banks of 4) if you have the GA-FC you can switch to 'Effects' mode and turn things on and off inside the patch, as well as trigger a programmable 'Solo' mode by holding the lit foot switch in patch mode all with your feet. Seriously practical.

Boss Katana 100 Gen 3 100W Combo Guitar Amplifier

Van Katana 50 MkII naar Gen 3 100: Een serieuze upgrade. Als eigenaar van de Katana 50 MkII vroeg ik me af of de nieuwe Gen 3 100 de moeite waard zou zijn. Het korte antwoord: absoluut. Hoewel de basistechnologie (Tube Logic) vertrouwd voelt, is de sound in deze gen 3 hoorbaar verfijnd en dynamischer geworden. De grootste winst zit voor mij in de functionaliteit en het nieuwe 'Pushed' versterkerkarakter. Dit gedraagt zich perfect als een buizenbak die net begint te oversturen. Daarnaast lost de 100-watt versie direct de beperkingen van mijn oude 50 MkII op: ik heb nu eindelijk een effects loop voor mijn looper-pedaal en kan de uitgebreide GA-FC EX voetschakelaar gebruiken voor live-situaties. Voeg daar de moderne USB-C aansluiting en de extra headroom aan toe, en je hebt een ontzettend complete versterker.

Boss Katana 100 Gen 3 100W Combo Guitar Amplifier

Heerlijke versterker met tal van mogelijkheden. Via de Power Control kan ik wat zachter oefenen, geen boze buren en toch een vette sound. Met een gekoppelde laptop zijn de opties eindeloos, maar via de knoppen op de versterker zelf kun je ook heerlijk experimenteren. Alles oogt en voelt van goede kwaliteit. Zeker een aanrader.

Mooie compacte versterker, met een volle vette sound ! Ik gebruik deze , in combinatie met voet pedaal GA-FC EX .
Waardoor de bediening, een stuk aangenamer wordt.

Boss Katana 100 Gen 3 100W Combo Guitar Amplifier

Fijne versterker voor thuis. Uiteraard zou de 50w versie ook meer dan voldoende zijn maar die mist echter een fx-loop die ik graag gebruik voor een looper.

De katana is super veelzijdig en klinkt gewoon super goed. Zelf gebruik ik de software op de pc weinig, de knoppen op de versterker bieden al meer dan genoeg mogelijkheden.

Ten opzichte van mijn buizenversterker doet deze echt niet onder wat geluidskwaliteit betreft. Het pushed model klinkt echt super goed. Het voordeel van de katana is dat het volume veel zachter kan dan de buizenversterker.

Jammer dat er voor bluetooth een aparte adapter nodig is, maar dat is ook eigenlijk het enige dat mist aan deze versterker.

Boss Katana 100 Gen 3 100W Combo Guitar Amplifier

Gen 3 is blijkbaar een nieuwe versterker t.o.v de MK2's. Dit hoor je in het geluid. Deze klinkt echt als een tube amp. De bluetooth adapter kocht ik erbij en is zeer handig om draadloos de software te verbinden of draadloos backtracks of muziek af te spelen. De hoofdtelefoon is nu stereo. De nieuwe PUSH mode is zeer goed. Dit geeft een cracked clean geluid. De software is ook aangepast, je kan je effecten chain aanpassen door de effecten in de juiste volgorde te slepen. Ik ben zeer tevreden met de Gen3. Ik had ervoor een MK2 100, maar vind deze veel beter op gebied van sound en respons. Verder bezit hij ook alle vroegere features van de MK2 serie.
