Question: are jazzmaster pickups single coil?
Answer: The Jazzmaster had unique wide, white 'soapbar' pickups that were unlike any other single coil. ... Whereas the polepieces of the Jazzmaster pickups are magnets, the P-90 has its magnets placed underneath the coil. The JM coil is wound flat and wide, even more so than that of the P-90.
