Yes.Obviously pc is much better suited for live,giving FRFR a more natural (ampintheroom)-feel but this is not what I meant.
For me everything helps which gives me instant tools to "free a good profile" from "the dirt"..no matter if it is some fizz or artifacts or whatever.Ofcourse you can do a lot "with tweaking" specially while mixing but again..this is not what I meant.The better the basic sound is the less you have to tweak it afterwards,and on the other side it becomes much easier to make it sound "even better" while doing the rough mix..some features on the kpa can help a lot to give you a "natural tube rig" sound from the very beginning without to get instantly into a more complex "tweaking mode".first of all I like as much "good,natural" basic sounds as I can get,no matter if it is about drums,guitars or voacls..the "tweaking" comes much later and includes the "whole big picture" as you surely will agree with me.
I guess most of us would not push the record button recording a great sounding marshall while they hear phase issues or fizz caused by wrong mic position etc..
