Hi there! I've got a Fernandes Gravity-6 string bass, and I think it's a wonderful bass. The thing is, I just don't like its pickups. They are noisy, low output and don't sound the way I want them to... I therefore ask if someone could recommend a replacement? I'd like the bass to be as flexible/versatile as possible - I do a lot of slapping, but also regular finger playing stuff. Thanks in advance!
