Although I've been a 4-string devotee' (snob) for years, I've been thinkin' of slappin' together a Warmoth-type fretless 5-string. K.I.S.S. rule: one passive pup. Two that come to mind are the RioGrande Powerbucker or a Bart P-type (for 5's). There's a Leo Quan Bada** bridge for fives, or maybe a Gotoh 206-type (for through-body stringing). I read about the development of Fender's Roscoe Beck (passive). I recall there was tweakin' on the pups because of some weirdness in the upper registers. Any thoughts ?
