I had many problems with feedback from piezos and piezo rod pickups when i was experimenting with them but use humbuckers now. The problem is that the feedback "field" is most sensitive when the pickup is  close to the amp, and increases dramatically as the volume goes up, making piezos only really practical for home playing, unless you don't mind standing 10-15 feet away!

I bought a new Amp last year, a Marshall ASD50D Acoustic amp fitted with an anti- feedback control that really works well if you want to play at high volumes close to the amp...and sounds great with Flatpup 4 humbuckers too (-:

Joe,

 

that would work, but, I prefer some "cushiony" material like silicone caulk.  The pickup side of the piezo (the shiny disc) needs to be attached directly to the top or the bridge.  The use the silicone to fill in behind the ceramic  side of the piezo.  Most of the feedback is caused by the ambient sound being picked up by the back of the piezo. 

 

While the neck does vibrate and will produce sound, the top or the bridge is the best source of sound.

 

hope this helps,
