Jason Lollar Overwound Precision Bass Pickup.
This was in an Original Senn custom p bass I had built and dates to 2012. The pickup is in awesome shape and Jeff Senn aged out the pickup covers so that they have the look and feel of a vintage instrument. www.jeffsennguitars.com
$75 plus shipping from Nashville, TN.
From the Lollar site:
Our standard split P, with a 10% overwind to add more “push” and fat. You’ll hear more of the fundamental with less overtones. Smooth and round, it’s great for adding a “bigger” sound to the low end.
