That's a nice bass but I think I prefer the one Turid from Katzenjammer is playing here:
But that's one plugged in as far as I can tell! Sacrilege!

I think this bickering from purists, is something in the vein of the "True Scotsman" argumentation fallacy. Change out the word scotsman to acoustic in there. That people wants to hammer down their stance as valid by applying some sort of preferential right of interpretation what "Scotsman/acoustic" is.
No true Scotsman - Wikipedia
Change out the word "scotsman" to any religious belief
s you have there. "Not any true christian does this", "no true muslim does like this" and off you go. Or acoustic, bluegrasser, hair metalists, whatever.
"
No true Scotsman is a kind of informal fallacy in which one attempts to protect a universal generalization from counterexamples by changing the definition in an ad hoc fashion to exclude the counterexample. Rather than denying the counterexample or rejecting the original claim, this fallacy
modifies the subject of the assertion to exclude the specific case or others like it by rhetoric, without reference to any specific objective rule ("no
true Scotsman would do such a thing"; i.e.,
those who perform that action are not part of our group and thus criticism of that action is not criticism of the group)."
"Imagine Hamish McDonald, a Scotsman, sitting down with his
Glasgow Morning Herald and seeing an article about how the "
Brighton Sex Maniac Strikes Again". Hamish is shocked and declares that "No Scotsman would do such a thing." The next day he sits down to read his
Glasgow Morning Herald again; and, this time, finds an article about an
Aberdeen man whose brutal actions make the Brighton sex maniac seem almost gentlemanly. This fact shows that Hamish was wrong in his opinion, but is he going to admit this? Not likely. This time he says: "No
true Scotsman would do such a thing."
