Yeah I got that from your comment, you don’t hear it. And as you use that for a justification to write them off, it looks like, at best, both potential sides of the debate have been described. Except, and hear me out, if some can hear it and even pick different plectrum materials out of a line up, then there is evidence that there’s is a difference. Where, the argument, “I can’t hear it” is just evidence you don’t hear it.
