I'm looking for a resource for parts for the Zenith bass. Shadow makes the pickups and electronics, but so far I can't get a response from them. I contacted Gibson, who responded, but said they didn't sell parts for the bass because I bought it used and it was over 5 years old. Sheesh. They told me to contact the pickup manufacturer. Round and round it goes... I have seen both Nanomags and Nanoflexs on the Shadow site, but I can't find any information as to whether they would work on the Zenith with its preamp and or the physical size, which they do not even publish that. Any input on this would be appreciated.
