Thanks for the plate acknowledgment. One issue I did not address is the process 
of exciting the plate to create the reverb then the mechanism to pick up the 
reverberated sounds. Inducing vibration in metal, then picking up the results of 
that induction is reasonably easy. Trying the same thing with wood seems to be 
more of an acoustical mechanical process. Maybe excite the wood with a 
loudspeaker (or one of those wall mount hi-fi speaker - subwoofer units) then 
use a Barcus Berry pick up for the return signal.

Though it may seem ridiculous your idea makes some sense. I've gotten some 
sympathetic tone ringing out of large marimba notes that I've built. I tried 
miking them up and it added a warmth to the sound if not an actual 
reverberation. I wouldn't use a sheet of ply though- the way it is laminated 
prevents it from resonating. If you glued some 1/2 thick cedar lengths together 
on edge ( and better if they are quarter sawn), hung the "plate" from its nodal 
points and plcaed a speaker and a mike close by you might get an interesting 
tone, if not an actual reverb. I've seen Mr. Beith's lovely plate units-this is 
something of a wholly other order!

The strangest thoughts come on the shitter....

We all love the plate reverb right?

What if one was made with a gigantic sheet of wooden ply instead? Like the top 
of a violin? What on earth would that sound like as a reverb?

Thought I'd share.
