In my mind there was quite a bit of good disco...the problem was the culture associated with it. Superficial, coked up people who had to do something to bide their time coked up dancing to repetitious music. Blondie's Atomic is in my mind the best disco song, period. It has a little bit for everyone including a tasty bass solo done on a Fender Precision.
ABBA's backing band was a bunch of killer musicians though I think the producer compressed the bass too much on many of the songs, limiting the bass' effectiveness but that's what happens in pop records. I actually have a problem with tons of recordings and not enough bass coming through the mixes. You can't win them all.
I do have to think though that Jamerson DID have a ripping sound on those old records. That fat midrange coupled with the thuddy old flatwound strings, priceless tone. It was in his fingertips, just like everyone else. Now maybe if he had a graphite neck to play with...
