Boss Katana sneaky amps and the original amps

So, I got kinda curious about all those ‘sneaky amps’ that is “hidden” within the Boss Katana guitar amplifier. And for that sake, those five amp styles available from the physical knob – what are they based on? Did some searching and didn’t really find a compiled list so I created one. And once that was done, well why not publish it here – hopefully there are other Katana owners that would be interested in this. Anyways here it is:

GT-100 Name – Katana LED
FULL RANGE (Original BOSS amp) – Acoustic
JC-120 (Roland JC-120) – Clean
TWEED (Fender Bassman) – Crunch
5150 (Peavey 5150 Lead) – DRIVE Lead
SLDN (Soldano SLO-100) – Brown

Another option is Gumtowns Katana FxFloorBoard editor that gives direct access to 29 amps. It also has a bunch of other nice features – follow the link to read all about it. There’s been some compability problems with the new Katana firmware updates but it works as it is for both Mac and Windows.
