Did you ever scan that article? If you did I would love to get one!
Here are some postst that I found on other forums (not structured):
The pickup suggested by the article is made by Shadow (general transducer at http://www.shadow-pickups.com/transducers.html). They paired this with a preamp a la
(http://www.shadow-pickups.com/pre_elec.html).
You could use whatever you want though. This is just a standard transducer running through a preamp designed to be fitted in an acoustic guitar. Better equipment is available.
The hardware they enumerate on their parts page, so you could take the list to a hardware store and have them get you the nuts & bolts. The fiberglass clevis yokes are harder to find though; your average Home Depot doesn't have them. I was thinking to look maybe in marine supply or plumbing supply.
As for tuning, guess we'll have to go to a local studio and record their setup.
thanks for the info acrossen. you may be in luck. Odyssey pro sound has a driver made by martinsound....

They also have some other accesories there to thast may be of some use although i will say the prices are bit steep for my tastes.
As far as pickups go. I guess i realize that there are many manufacture's making items that will do i am mainly just wondering which one will work great.
Especially since i have no real means of testing them first.
What I do recommend is for the plate outlined in Bob's article is to use Stainless Steel of the following specifications:
Type 304 with a #2B finish - Cold rolled on polished rolls, annealed, pickled, and skin passed on polished rolls.
The dimensions should be 36 inches by 72 inches 26 gauge thickness.
