I'm sorry, I certainly didn't want to argue.
No problem, it did not come as if you wanted at all
I've seen no facts regarding any of this stuff. Just some reviews written by people's opinions.
Well, charts and measures do are fact. You can't measure a guitar combo in a manner which gives you valuable info about what to expect, but you can measure a device designed to be linear or accurate under any respect. It's just a matter of finding what to measure, and to build standard procedures so to be able to make coherent comparisons.
Anyway, I want to help too! As for me, answering a guy who writes "I didn't like the X device", and who probably didn't even know how to operate it, does is helping him. I don't criticize opinions, but if I have the impression that those opinions are bad-formed for any reason I always try to correct them. Not too much tho, since at the end of the day what matters is that people are happy with their gear. Unless some comes up again with the notorious "the Kemper sounds digital to me" or "the CLR sound boomy to me" statements. The presence of that "to me", which is often just a way to cover their a**e, doesn't make a shareable opinion out of the sentence.
In this case, helping them means to show that it's user error and not the device's fault, IMO
Peace and regards
Peace to you, buddy
