Hello, I'm predominantly a guitarist, and I'd like to learn some stuff. I'm currently working with a yamaha trbx 305, and I'd like to upgrade the pickups. I'm just not exactly sure what to look for, for this style of bass. I play metal for the most part and am wondering what's a good pickup to upgrade to for the genre. I know it's a loaded question because it's all about opinion, I'm just looking for a starting point. Also it's for studio use only. Thanks for any input!
