Prince was a huge Larry Graham fan and at some point insisted his bassists play 4 string Fenders or Fender like basses. Synth bass and octave pedals are used for songs lower than E. I've basically gone back to playing 4 strings. I do play my 5 but only on jazz gigs and when singers lower song keys a lot. Around here, 5's and 6's seem to be a 'thing'. I started playing 5's out of necessity in smooth jazz and gospel bands. I play mostly old school music these days.
