i own the L-1505. it's awesome. i don't have any measurements for you, but the neck pickup is pushed a little more towards the neck. no complaints. it also has a single mod instead of series for the neck pickup only...
here's a nice dark grainy pic that doesn't even show the beautiful honey burst.
p.s. an L-1500 or climax with the same mod would be my hands down bar none forget the rest desert island bass.
