Steppin_Lazor on KIT-11606 - Bleep Drum Kit

I have the Dam Drum 2.0. and dig it! :)

Unfortunately, it has massive hum when I hold it and a lesser yet noticeable hum when I don't. I'd love to be able to use it as shown in the video http://stonesthrow.com/news/2013/01/dam-drum but can't.

Is my DD2 defective? Any ideas? Does the Bleep Drum have the same issue?

Also, does the DD2 have the Noise30XX mode? If not, is it possible to add it?
