What's wrong with my BG1?

[amfortas2006]

The last time I brought my BG1 out I heard some strange soft distortion all the time, so I did a small test showing the distortion.
I also tried changing cables and settings and it didn't help.
Do you guys know what could be wrong with it?

I used Schoeps>BG1>minir82

I also recorded the same test trough the internal Sonosax preamps, and they don't show these artefacts... (next post)



Thanks
