Experiences with the Sustainiac Model C Unit?

[SausageofPower]

I'm looking at pulling the trigger on one of these as a new toy. Any experiences people would like to relay? I know plenty have used the electromagnetic unit that comes on guitars like the PC-1, but I haven't seen anyone on here mention the electroacoustic model.

Err, sorry. This might work better in the amps/effects section. My bad.
