When I say melodic in this instance I mean clearly less interested in chops, having a voice more in a folk/ambient/free/new music sense. Someone who uses space in a relaxed and thoughtful way, somewhat detached from the usual role of the bassist. The players that come to mind for me are Charlie Haden and Thomas Morgan. Who are some players you dig who have a similar element to their playing? *Feel free to include any electric players. One I found about lately is this guy in Sweden named Gustav Broman, he plays a cool Hofner hollowbody with a real acoustic sound.
