I bought the Harley Benton GuitarBass VS Vintage Series which is very much like the Fender VI. It was great but the bottom E flopped like the elastic in very old underpants, had no sustain or punch. I understand the Fender is the same (so the internet says, I've not played one). I used the E off this set and now it sounds great.
I have song using it, search YouTube for daveeff belly of the whale & hopefully you'll find it, bass solo 1:55 in.
