I've built my very first CBG and installed a simple , single piezo w/o volume control . Mounted it right under the bridge as well . The connection between the jack and amp cord is good but I get no sound at all . Having max volume on the amp does no good . Anyone have any ideas ?

Step 1, plug into another instrument to make sure its not your cable or amp.
workd fine with my elec/acous guit
Thanks john . Glued the piezo to the underside of the top . Due to the soft cedar wood construction I reinforced the top of the CBG where the bridge is mounted . Maybe its too thick to pick up the vibration of the strings ? I bought the piezofrom CBGitty already soldered .
No such thing as too thick... the piezo will pickup any vibration. Where is it located? can you take a pic of the piezo as mounted?
Is there anybody around here who could explain Todd how he gets a piezo on a cbg with a hardtail bridge working? Something I would never try out as I'm rather on the acoustic side...
It's not about the bridge type, though a lower-mass bridge MIGHT transmit more vibrations to the top... If it's glued right under the bottom side of the bridge, it should work ok...
When my piezos don't work , I find its the jack or the solder joint to the quartz element of the piezo. I bought a huge bag of jacks from China cheap, and the sleeve of the jack is crmped into place. If the crimp is loose or not tight enough the sleeve will spin and it can cause a short.If I had bought a prewired piezo and it did not work or stopped working, I would take a multimeter to it to test the components.I would look for a short caused by the jack, or an open in the wire.On my builds when the jack is not the issue, I find the solder joint to the piezo has "popped off" from a weak solder joint.I but piezo's in bulk, but each batch is a little different even though I order the same part.Some are easier than others to make a good connection to the quartz piezo element. The bottom line is use a meter to test, and if you don't have a meter find a buddy who does. Sorry for the wordy answer.,.,
You need to check the piezo for a broke wire/lead or a broken crystal(ceramic material on top). Could be wires are crossed, cold solder joint or just a defective piezo.
wires crossed won't make a difference. other things you mentioned are all possibles.
Depends where they're crossed, like at the jack or the pots.
