If you were putting together a list of the greatest synth bass parts of all time, the one from Stevie Wonder’s Boogie On Reggae Woman - taken from 1974 album Fulfillingness' First Finale - would have to be on there.
Played by Stevie on a Moog synth, not only is it a great sound, but it’s also full of slides, bends and a ridiculous amount of groove.
