The DiMarzio Relentless P Bass Middle Pickup in Gloss Black Metal is a powerful passive bass pickup conceived by the brand and Billy Sheehan with a smooth, optimally spaced construction that sound mean, heavy, yet dead-silent with virtually no electromagnetic interference. With a compound radius cover that matches your fingerboard arch, and rounded edges to avoid intrusion when playing, these are the types of pickups you'll never have to work your fingers around. Producing punchy mids, snappy highs, and precise lows, the Relentless pickup is perfect for all styles and genres.
