I own a used warwick corvette standard 5 string bass. It was equipped with two mec jazz style pickups. Unfortunately, both pickups started sounding really nasty and aren't fitting my needs. I am in a position to by two new pickups. I need some help and some expertise in what sound i am looking for. I am in need of some closed-coil jazz style pickups with a huge slap tone available in them. possibly seymour duncan or duncan design.I need to find them for cheap. If anyone has any input as to what I should purchase I would be most grateful. Thank you. Please respond!
