I have one and it is worth the hype. They sell out very fast. I have owned a 101B and also built a clone of one and this module is the real deal.
Also download the pdf manual from the Synergy site to see the dip switches under the the tube metal grill.
The 2 small dip switches are labeled 100B/101B and AIR ON/OFF
The way mine arrived was the Switches in the 100B and AIR On position.
I prefer the AIR switch ON, and the 100B/1010B in the 101B position.
BTW it sounds best with a nice fire breathing EL34 power amp
