I just got a Katana 100 and I've only played with it for half an hour but I can't get anything near a Fender Tube amp tone like I can with my Mustang GT 100. There is just no bottom end, it sounds flat. I have tried scooping the eq. I haven't, as yet, gone into the tone app to play with the more extensive eq in there. Why, you might well ask, am I trying to get a Fender tone when I already have a GT100? Well, I've just landed a regular gig where the amps are provided. One is an AC30 and the other a Katana 100. I will only be taking a guitar (Telecaster) and a Helix HX, which has no amp modelling. Does anyone have any experience of tweeking the Katana EQ to get something closer to a Fender Amp tone.
