Ken:
FWIW the bass player in my band was playing a Fender Jazz. About 4 months ago I stumbled upon a 5 string Epic with a superb flame walnut top for a song on craigslist (the extra string being a B below the E). I grabbed it and let him have it to spec. At that point he had only tried a 5 string briefly and felt completely confused by it. He took the Epic home for a week and came back to rehearsal in love. He quickly got used to, and loves, the low B. And I love hearing the sound of his bass (through an SF-2 and an old Traynor).
