Okay, all metal. I didn't know. There's still no need for earthing. Reading your OP again, I'm pretty sure the problem is circuit noise. Maybe the PSU is unregulated. Check with the maker, anyway. Is there a gain or level control?
Thanks to all for your input. I've kind of sorted out the issue. I turned the input level on the RC300 up a lot which allowed me to turn down the amp. This helped a lot. I still can't turn the gain up too much on the amp. Maybe to 3 out of ten, but that's okay by me cause I play a pretty clean tone. I plugged headphones in to the RC 300 and they were clear and clean.
