I have one of your Volca PSU's.

While I do think it's great I also get a huge amount of line noise which I understand is common when using a multi PSU... Unfortuantaly this makes the volcas almost unrecordable.. especially the FM and Bass... Is there something we can do about this?? I have refrained from leaving any negative public comments or reviews in the hope we can sort this

This can be caused by a number of factors, please have a read of blog post about the issue. Ground loop isolators will also fix the issue, but checking your full set up should help identify the cause. Do let us know how you get on and talk soon.
