We should be comfortable tolerating and considering a range of views on these topics without unduly personalizing the discussion. I don't profess to know everything nor do I insist anyone do or think as I do. And since this is a Dead gear forum, all of us, to a more or less extent, are "chasing the dragon." I do, though, sometimes present an alternative viewpoint here on how to approach covering the Dead.
My take is often this. If we truly want to respect Jerry and his heritage, let's be inspired as much by his overall approach to music as by the physical things he used to make it. Just as we love and cover Jerry's music, Jerry loved and covered other artists' music. There are so many great examples.* In doing so, when, if ever, do you recall Jerry striving to slavishly copy the gear and tones of those who inspired him? In Jerry's own words, "There are more good guitar players alive today than have ever existed. I welcome it. It’s been a long time getting here, the legitimizing of the electric guitar. Everybody has something to say. I really feel that you can’t avoid finding your own voice if you keep playing. You have a voice, whether you recognize it or not."** Did Jerry strive to ape Chuck Berry's tone or cadence when he covered Chuck? What do you think he'd advise you were he still with us and you told him you were hell-bent on copying him exactly? Might it be, "You have a voice, whether you recognize it or not."
This is a valid viewpoint, too.
So my personal approach - what I apply for myself in my own "amateur" musical pursuits and sometimes share for consideration with others without trying to dictate anything to anyone - is simple. Learn about how Jerry got his tone, and then be comfortable enough in your own skin to apply as much or as little of it as your preferences and budgets allow. Never be afraid, unwilling, or intimidated by "what Jerry did," "what most people think," "what professionals advise," etc. to do the unexpected or to differ.
