Some gear is reformed some is refurbished. :-) But a recording can be a crap shoot sometime.
Janis Joplin has always been a favorite, but finding a great recording including some 15ips RtR 2nd masters, sucked. It was better than what I had but it was just rougher than a cob.. They didn't dub anything they just recorded it. Good, bad, or wasted, it got recorded.. One recording I heard 5 zippo lighters slam shut through the recording..
I call it "John Wayne" recording. "We whipped out another one,...... Pilgrim!"
