Every time I plug my bass into my soundcard for recording , I get this static noise in the background. Sometimes its very loud and sometimes its not. I have tried to use a DI box, but that didnt help at all. The noise is first noticeable when my fret hand is not in contact with the bass. This happens no matter what kind of bass I use. I have tried 3 different bass guitars. This does not happened when im recording guitars or vocals. I also get the same noise when I plug my bass in the amp. Anyone who can help me out?
