The 9SU L/S is the Fender Jazz Bass ( J Bass ) replacement pickup set with a long for the bridge and a short for the neck. The set is highly respected by musicians and luthiers alike for its deepest tone out of the J Bass pickup family. They feature a single coil design.

The original series� bass pickups with passive designs. They are cast in epoxy to remove unwanted feedback and microphonics.

The lengths of the neck and bridge pickups in the original J-basses are not equal. The neck pickup is 3-5/8" long which is slightly shorter than the bridge pickup which is 3-3/4" long. Some modern designs, however, use two long bridge-length pickups. In this configuration it is important to use the LN� (long neck) pickup that is specifically designed to work in this position (do not use a bridge pickup in the neck position). Some (very few) use two short neck length pickups. Please check the physical size of the pickups you want to replace to make sure the replacements fit properly.
