It was my first time laying down with the Zon. We would record fine but on playback there would be an occasional 10-15 second burst of "static". I had a fully charged battery and even plugged in the power adaptor but that made it worse, creating a bit of a "whine". It really only bothered twice, mysteriously appearing and going away. We were able to get the work done but my confidence is shaken in using it again. My God, this bass is great but I have no experience with the Lighwave system. Perhaps the shielding isn't up to snuff? It's a Sonus 5 fretless maybe five or six years old. Maybe there are updates to the Lightwave pickups? I don't know where to start...
