I'm looking for a bass to complement the two basses that I'm using right now - a Sadowsky MS5 and an Ibanez GWB1 Fretless. They are both active, and I'm looking for a basic alternative. I want a 4-string jazz bass. I'm looking for a classic jazz bass sound. The marcus miller is active, but I'm thinking of a couple of mods: changing the stock pickups and preamp, and adding a passive tone control. I was thinking about putting some Lindy Fralin pickups and an Aguilar OBP-1 and stacking the bass and treble pots. Then I though ot putting a passive tone on the fourth pot. What do you think of the preamp and pickup choices? Do you think this bass could deliver me a basic passive jazz tone, and when needed I could get a hifi-kind of tone with the preamp? I would also like a bright slap tone. So, do you think this bass would give me what I want?
