We currently offer Precision and jazz bass pickups (4 and 5 string) the only covers you can get for bass pickups are black white and cream as they are plastic, not metal like the humbucker covers.
Our bass pickups have a very warm, open tone. Based on the wind Fender used in the 60’s before they moved to smaller wire gauges and their sound went very thin and brittle. Ive found that you can get an enormous range of tones from them just depending on the way you play, whether it be finger style, with a pick or slap.
We have sold a lot to French jazz players who adore them, as do I.
