The original pre EB basses shipped with GHS strings (flats till early 78) - if you really want to get to Bernard Edwards authentic - however you have to play exactly like him as well!!
I remember seeing an interview with John Taylor, who ended up with Bernard's bass.
He recounted with great sadness, an accidental act of art-vandalism, when his roadie - thinking he was doing John a favour - cut off Bernard's strings, and put a fresh set on.
The thing is, if you go and watch Bernard's final show, on the night he died, in Tokyo (it's on YouTube, in full), he's playing his Stingray through a Trace Elliot Series 6 stack of 4x10 & 1x18, and clearly has a nice fresh set of strings on the bass.
Not surprisingly, he still sounds exactly like classic Bernard Edwards (so it's not really the end of the world that John's roadie killed the strings, or vital to Bernard's sound, to have old, dead, flatwound strings).
The video clearly shows both of his amp settings : his rig has a slight, broad mid scoop - and the head feeding the duplicate stack behind Nile Rodgers (so, no doubt not affecting the recoded audio) has the low end rolled of, and a high mid bump).
