A luthier told me that Bartolini will custom make a "jazz" pickup that is in the same shell as their standard soapbars. Here is the quote... "Bartolini can make a great sounding Jazz pickup that work well with a low B and are very low noise. They can custom make this type of pickup in the same shell as the ones on your bass. However, they may take a year to get." Has anyone heard of these? If so, what do you think of them?
