blimey, so much choice!! I have finally fixed up the neck and re glued it so i will test it out tomorrow once the glue is fully cured. I like the idea of wood slabs to keep the tone bright, but wouldn't it still get lots of feedback? so far the foam idea is my favorite.

St Ginger,

 

If you don't sandwich it and glue it between two thin slabs of wood, and sit it right under your bridge (method 1), then you could lay down a bed of hot glue, insert the piexzo, and dump some more hot glue on top of that (method 2), or do the same thing, except no glue, with clear or white bathtub silicone (method 3). There are also the double stick tape method, the foam wrap method, and the rhythm method. >:-E

there's a big discussion going on on one of my other pictures about my problems with the action of the neck. but once that is fixed i will give it a test and find the sweet spot :D

I'm planning to glue a small bit of sleeping roll foam or something to the underside of the top, then glue the piezo to the foam. would that help with the feed back and unwanted noise?

should i cover the TOP of the piezo with hot glue as well, seal it onto the top?

go with your first idea--- hot glue it to the lid right under the bridge---use a nice thick bed of glue and you will minimize feedback---I have built nearly 30 piezo guitars, and they all sound great!

close to the  bridge  is  usually a good rule of thumb  . i  dont really  like  piezos  ,  but  a light  foam    wrap  worked for me  best on   one build .  lukey i  had  good  tape .

hot glue seems to be popular .

Put the piezo in your first most likely spot, right under the bridge, with some double stick tape. Clamp your top down with some edge clamps. Add bridge / saddle and strings. Rinse, repeat until you find your sweet spot. Then you can glue it down, once you are ready to put the top on for keeps.

the problem is that it needs to be attached to the underside of the top, but in order to have the strings on the top needs gluing down. the sound holes aren't big enough to get in there and work on it with the top on, so i need to do it before i seal her up. 

any idea how i could find a good spot, or a general rule of thumb for placement, without testing it? i'm not really bothered about the quality too much, its going to be primarily acoustic. and what wouldd you say about attaching the piezo; layer of foam, piezo, hard glue in a sandwhich?

i wouldnt  glue that  piezo down before  you  find a sweet spot  , and  test it for feedback   etc  with the strings on  .. you  may want to   cover it in  hot glue ,  tool  dip,   or   foam .  they can  get  pretty sensitive .

most  like to at least  put a layer  of foam between the  wood and the piezo .

this   avoids   sqealtch ,, feedback  and  unwanted noise .

me too  :D  never used them really, i didn't realise how simple and easy they are.

I like piezos.
