........I guess the point of this post is... does anyone have any info on jerry's signal once it left the speaker?
It's my understanding that there was nothing at all done to Jerry's tone after it left the speaker. It was simply mic'd, typically with a Sennheiser 421, sent to a Crest/Gamble console with high quality mic preamps - and if there was any EQ, knowing Healy's general philosophy, he may have shaved off some low bass with the console's hi-pass filters. But I really doubt that Healy did any kind of treble reduction or EQ'ing to Jerry's channel. If so, it would have been very slight. Healy is VERY anti-EQ, anti-phase distortion.
Regarding signal (treble) loss thru long cable runs, that's generally an issue in guitar setups with high impedances. Balanced low-z runs like we use with PA systems don't suffer this loss as the cable capacitance has a VERY small effect on low impedances. The Dead's sound systems were very flat response and balanced and low-distortion. I don't see how there would have been any shaving off of highs from Jerry's mic channel. I think that a lot of what we hear in that warmth and smoothness in Jerry's tone had to do with him being so super loud, pushing the speakers and the amp. The natural result of that is a warming over, a taming of the crisp brightness, a fuller midrange.
