Little Sparrow is a humbucker floating pickup for archtop, hollow body guitars.
The idea is based on the structure of the legendary Johnny Smith, one coil has a bar magnet in it and the other has bar of steel . The magnetism travels from the bottom of the bar magnet along the steel bottom plate to the bar of steel of the second coil.
It is low output pickup with DC resistance 6.4 K and a lot of acoustic behavior.
The pickup has a classic clean vintage jazz tone with acoustic quality.
