Hi! Looking to use my Yammy RBX374 as a project bass. I'm looking for pickups to replace the original humbuckers, and probably go passive. I've searchd for hours, and the only thing I've found is that the Yamaha RBX774 pickups are split-coil under a soapbar cover, but finding those is impossible, and I don't know how they'd sound in passive mode. Thanks in advance!
