This is a single-pickup (half size) cartridge loaded with a Gretsch-style Filter'Tron pickup. It can be used in either the neck or the bridge position so it's like getting two pickups in one! The Filter'Tron is a humbucker with warmth, however it has the brightness and clarity of a single coil making for a truly unique tonal palette. It is great for jazz, blues and with a little bit of overdrive you'll have a signature rockabilly sound. Artists like Chet Atkins, George Harrison, Brian Setzer and even Malcolm Young have been devoted users.
If you are looking for another pickup to pair this one with, consider the PAF humbucker, they sound great together!
