Hey I was wondering if I could get some pickup advice, seeing how I know nothing about them. I just re-discovered my fender highway-1 jazz bass and have come to find that I really like the feel of the neck but the stock pickups leave something to be desired. I'm looking for a pretty "bassy" sound but still be able to cut through and be heard (much like chris white of the zombies or many mars volta tracks or james jamerson's funk machine), I'm basically looking for that classic rock sound. I play through an ampeg svt classic head and a 610 cab so I don't think it should be that hard. Are there any pickups that you guys can suggest that will really bring about a noticeable difference in the sound of this bass? Thanks a lot!
