There we go - I like em thick and full, too, "even" in Jazz - check out Drew Gress on Marc Copland's CD "Haunted Hearts (and other ballads)" if you stop by the iTunes store the next time, one of the most pleasing bass sounds I know on any recording. He seems to be playing a pretty big bass too, I was always wondering what it might be, it's just got everything, the deepest lows and crunchy bite (he's a main ingredient of that sound recipe for sure):
