This turned up on the TV a couple of days ago:

One's already on its way here. As the video progresses and we get to the real 303 meat...and, oh my god...they DID IT!

See, the problem with replicating the TB-303 is two fold:

1) The filter doesn't have enough "grit". And...

2) The "glide" isn't easy to do...because Roland probably did that function "wrong" in the first place. But I was amazed when this did that "not really linear" portamento that's key to the 303 sound...and that's something that NO ONE has gotten right throughout the history of 303 clones!

...until now. And they even added a little bit of craziness by putting a headphone-out jack right next to the aux input. Minimoog feedback trick, anyone?

Just to make sure of this, though, I'll be putting this on a scope when it gets here so that I can look at the glide activity and a few other things. But when the demo switched for a bit to that wonderfully-hollow squarewave sound...wow. Just...wow.

Looks like Uli's got some competition over in China!
