Hey folks, first post, and I really could use some help. I've been trying to install EMG J-X pickups in my jazz bass and I've hit a real rough patch. One of the solderless pickup wires is missing. From the factory. I don't know what to do. Can I solder wires in place of the ones that are missing? If anyone has experience installing EMGs in the JBass, I could really use some help. Maybe a quick walkthrough. Thanks guys.
