To kind of put them all in one place. What are the different spacings on pickups on the Jazz bass from the 60s-70s-present? What kind of different tones do these accomplish? What is the current Fender spacing in relation to the other? Is it un-changed from the 70s? Most of what I hear about is the difference from the 60s and 70s. Not to mention all of the RIs which capitilize on the certain era of build. It is an interesting topic for me and why its important.
