So I've come to a bit of a rough patch in my growth as a player and I've decided to spend a lot more time listening and a lot less time intellectualizing the music. To that end, I've been listening to the Miles Davis Prestige Sessions (Workin', Relaxin', etc.) with Paul Chambers. I figured many of you have been listening to recordings from the 50's longer than I and I was wondering if there were any good EQ tricks to make the basslines a little more audible when listening.
