I've had my Katana 50 MK1 for a couple of months now. I just use the panel for all of my setting. I can get some pretty good tones from it, but I'm still confused about Gain vs Boost vs the high gain amp models. If I use the Lead or Brown models, I pretty much have to turn gain to zero to prevent chords from sounding like a wall of fuzz. Forget adding OD or the Blues Driver to either of these models. I have to use the Clean channel to use the boost drivers. Do I use clean plus a driver, crunch plus gain, or brown with 0 gain? Just confused.
