It is under the lid off to the side of the neck as it goes through the body.

Sorry, I misunderstood you. What did you use to glue it to the lid?

Hot glue or epoxy works the best, in my opinion. You have to make sure whatever holds it to the lid transmits the vibrations to the disc.

Super glue.  Was that a bad idea?

Pop it off and try hot glue or epoxy. I think you will find it will work a whole lot better.

Piezos feed back if too close to the  amp speaker - there is an acoustic amp with a built in anti-feedback switch, the Marshall ASD-50D 50 watt combo, but sitting several feet from any ordinary amp and keeping the volume and gain down will cut out the feedback - unless if there when you want it!

This feedback isn't quite like if I plugged my acoustic or an ES330 or a Casino into my AC15C1.  I get what you are saying, and even have it on a 15 ft. line with me facing away from the amp and me between the amp and the guitar.

I normally embed a 27 mm piezo in my bridge under a brass or black threaded bolt without much feedback issues. My last build I tried another disc in parallel and was getting a lot of feedback with it mounted on the box near the sound hole so I moved it to the neck and eliminated most of it, the thing is experiment with the placement. Just tape it in so that you can move it arround, then when you do find a sweet spot glue or silicone it in place. Also the amp is key as well, I use Billy Gibbons theory on larger amps with the CBG using a piezo.............no treble, full bass. Good luck and have fun jammin.
