Hi guys - I've got a Samick J-Bass that I love, but the sound just isn't it for me...I'm more of a P-Bass low end thump sound kind of guy than the more refined J sound (or that's what it sounds like to my ears...) Any recommendations on pickup upgrades that could give me the sound I'm after, or a step in the right direction? Was looking at EMGs, but most of them are active, hoping to go passive...any help is appreciated! Thanks!
