Definitely my favourite era of music, so much 'space' in the music and prominent, full bass tones aplenty....
My personal faves HAVE to be Peter Cetera (Gibson EB3L & Fender P) on the first 11 'Chicago' albums...... and Tiran Porter (Gibson EB3L, Fender P & Gibson Thunderbird) during the original Tommy Johnston-era 'Doobie Brothers' . Both played with taste, melody, rhythm and finesse..... and their bass parts were clearly audible!
Also love Joe Puerta (Ambrosia), Leon Wilkeson (Skynyrd), Kenny Gradney (Little Feat), Dave Hope (Kansas) etc...
