Session bassist Ronnie Baker was a major contributor to the ‘Philly Sound’ of the '60s and '70s.
Using the classic soul setup of a Fender Precision Bass loaded with heavy gauge flatwound strings, Ronnie laid down some of the baddest soul and disco basslines of all time on treasures like Bad Luck by Harold Melvin and The Blue Notes and Jerry Butler’s 1968 album The Ice Man Cometh. Look up Jerry's Hey, Western Union Man. It’s a doozy. Oh, and in case you didn't know, Ronnie also cut the greatest disco bass line of them all...
Band: Philadelphia session ace
