I just ordered a Brice 6 string fretless, and I was wondering what some good pickups would be to drop in it. I want a really warm, fat sound, but still able to bring out highs if i need it. I was thinking barts, but their website doesnt advertise 6 string pickups(or i am bad at finding them). Any opinions? edit : i have barts in my roscoe, but thats fretted, would the tone differ much with a fretless?
