Hi, I have a wilkins p bass with alder body&rosewood board equipped with hipshot A-style bridge and SD SPB-1 pickup. I changed the round string to EB flatwound string. The bass and the strings both are awesome. Now I want to change the pickup. SPB-1 sounds okay but I hope to get a more live , dynamic and clear sound without loss of the meaty, warm and fat characters. I have some choices: 1. Lindy Fralin vintage p 2. Nordstrand np4v, np4 or power blades. 3. Aero p type 1 or 2. 4. Delano PC4 AL or PC4 HE Please give me some suggestion! Thank you! By the way, I'm very interested in Delano Pickups if there any one who have used Delano pickups. How their pickups compared to Bartolini & Nordy's?
