FAT is pre-gain.
I'm not particularly interested, myself, and it seems it can be done with a simple EQ in the Kemper, or by lowering definition.
SAT also doesn't really strike me as exciting, seeing as BE on 7 is perfect and HBE on 7 is overboard. We're hardly short on gain.
It may be nice to do some selected profiles with gain reduced but SAT kicked in to compensate, but that's really... particular.
I found no mention of the CAT option, i'm guessing meambobbo meant C45 - if so, i concur. Would love it both on and off.
I'm with meambobbo - B7M6T6P5 was best, but mids on 7 will be alright, i can EQ later. Gain on 7 for the BE, master on 3.5, 57 on-axis sounds lovely.
Haven't tried the last phases yet so i can only say that theoretically, i'd love a little push to the top end and a profile with the C45 switch on.
Obviously, if you see two options sound overly similar, just ditch them. I don't think many would mind, and the difference of one point on the EQ scale is often not as drastic when recording.
I'll probably get to say this a couple more times before this is done, but a huge thanks. You're doing an awesome job, and this is already making some waves in the community - I think we'll be seeing more communal projects around soon.
