I have a set of Ghost saddles in a bass. I once had a Bolin NS bass and foolishly sold it. I NEEDED something else. Live and learn - one day maybe. Anyway, it had a lovely, lovely piezo sound. I have tried to recreate that with this set of Ghosts. I have not managed, I do not know if it is the bass, the saddles or the preamp or a combination of all. They just do not bloom like the Bolin did. Mind you, nothing else has either (MM Bongo with piezo bridge and another custom).
