de Jazzmaster bevat volgens mij zogenaamde "soapbar" pickups. Van de Jazzmaster Wiki:

"The Jazzmaster had unique wide, white "soapbar" pickups that were unlike any other single coil. Jazzmaster pickups are often confused with Gibson's P90 pickups although their construction is similar but not identical".

Of er klakkeloos p90's inpassen durf ik niet zeggen.
