I just put this in my classic vibe 60s precision bass. There was nothing wrong with the stock p bass pickup that came with it, I just wanted to try something that fits with the style and era the bass is going for. I love how it sounds; a very full warm tone like you would expect from a vintage fender. What are your opinions on this pickup if you have ever heard or used it? What other p bass pickups do you prefer for doing mods?
