My 12 year old son has expressed an interest in the bass, so I am doing some research to try and figure out what to get (I play acoustic guitar, so I'm fairly clueless about bass). I have seen a lot of positive posts regarding the Essex line at RondoMusic.com, and will probably go that route. The main decision seems to be whether to go with a P bass or J bass. Other than personal preference, are there any compelling reasons to go one way or another? Thanks.
