It’s worth listening to the audio examples. It sounds exactly like you’d imagine — washing machines getting tapped, thumped and slammed. I sampled the water sloshing in my washer years ago for a track; this is precisely the sort of thing you should be doing for yourself, not buying a sample set.
Though I wish this guy well. Everything sounds very well recorded and he spent extra time with Kontakt programming to make them cool. But really, isn’t it a REQUIREMENT that you sample junk around your house for yourself?
In that unwritten book of rules for electronic musicians, that is!
