At first I was having some real trouble getting sound out of it. Then I read the manual -- you can't plunk it on a tabletop and get any sound out of it because having the volume loop in proximity to anything grounded basically turns the sound off.
I found this out after finally having a look in the manual. I also found this out at 10 AM this morning, with the gain on the input jacked all the way, with my monitors turned up. So Sean got the rude awakening of a very loud theremin howl. He came bounding up the stairs and said "DAD! HEADPHONES! SERIOUSLY!"
