DiMarzio Model P bass pickup, DP122

From the manufacturer:

Breathe new life into any bass by replacing its stock pickup with a DiMarzio Model P®. This hum-cancelling two-piece pickup brings big, punchy sound to Fender® Precision Bass®-style basses. The DiMarzio Model P® accurately reproduces the sound of your bass with added gain and solid tone. DiMarzio Model P® pickups cut through the band without sacrificing bottom-end power. Gutsy mid-range provides growl when the bass is pushed hard. Combine the DiMarzio Model P® with a bridge position DiMarzio Model J™ or Ultra Jazz™ to achieve any tone from a tight mid range punch to a warm bottom-end with bright, clear attack.

Heavy sound with midrange emphasis. Aggressive sound designed to cut through dense tracks and loud situations.
