Great lows and mids. Old school sound. I've tried the Dimarzios Ultra Jazz but they are too modern sounding. If you like HiFI bass sound these are not for you, but if you like dark sound, with a lot of pressece these are the best you can get, better than SDs quarter pounders. Output is high, and hum not present. I have all my "fender like" basses with Dimarzios.
