Question: what is the difference between a jazz bass and a regular bass?
Answer: The Precision Bass [or “P Bass” as it is known] has split coil pickups that give it its classic, solid bass sound. ... The Jazz Bass [known as a “J Bass”] has 2 single coil pickups which results in a very clean tone that has a bit more midrange than the Precision. Tonally think Jazz, Blues, Reggae and Funk Bass lines.
