I got a Fender MIM jazz bass with the exposed pickup leads and after trying flats, rounds, tapewounds and half rounds i've found the sound (especially the neck pickup) to be hollow and just not as a hot as the bridge pickup (mind you i even have taken the bass for a setup with a luthier and still the sound does not convince me). Im looking for a thumpy yet a little growly fretless bass sound that can be cut through the mix. Ive been pondering the following pickup replacement options: Dimarzio Model J:Thumpy and vintage. Its my first choice. Aluma J pickups (lace): I heard wonders about this particular set of pups. From a recomendation of a colleage who says the output is high and the sound is even all across the strings. Any more opinions??
