Just realised I never replied to that, @Just Wrong. They are two very different basses: the JMJ's body is a tiiiiny bit bigger, and the neck a bit fatter. It sounds more growly than the 73. The 73 is smoother in every way: the body is smoother (it might even be a bit thinner), the neck is slimmer and the sound is a bit fatter, with less attack. That might also be a bit due to the different strings: the JMJ has the original long scale Fender flats, the 73 has LaBella Mustang flats. I am corrently on tour with both and have played the 73 most of the time. It fits the Northern Soul vibe I need a bit more. And I like the neck better.


OTOH they will only gain value over time.
