Alright, who's going to be the guinea pig? An interesting departure from the 3-4 individual sensors; not unlike the former B-Band SBT. Totally passive, minimally invasive, and I think James includes a stereo jack as he did in previous iterations. There's a "ring" solder point on the input jack pcb to add a second souce be it a magnetic pu or mic (power would be supplied via external preamp).
