Old tone for me is when you just get together with some mates in and old barn and rip the shit out of some old tunes. Too much stuff is way over thought with too much tinkering with what the guys have been playing.
This is Old school. Four guys jamming in a barn with some beers. One mic each and mixed down onto a PC in one take. Lots of bleeding over. Played too loud Half an hour balancing to two tracks, done. Just like the old days. I just get bored tinkering with tunes for too long and trying to get all the rough edges out. Often they need leaving in. Lets just hear the guys playing. None of us are or want to be Steely Dan...
I've cut it short for brevity. That tune just goes on and on....
