I have a piezo transducer from an old smoke alarm, and I want to stick it in my strat to use it as a contact mic. I'm thinking about gluing it to the block the strings go trough under the bridge, but I'm not sure exactly how to do it. I want it to pick up as much vibrations from the strings as possible. so. What kind of glue do I use? What's the best spot to place it? Anything else I should be aware off? The wiring in the guitar is a fairly standard Brian May wiring with master volume and tone. I'm thinking about using a SPDT-switch and connect the hot wire from the standard wiring to one side, the piezo to the other side and the center to the jack output. Would it be possible to use a on/on/on switch to have both piezo and pickups in parallell? Or would that cause any problems? And what would happen if I put the SPDT switch before the volume and tone? That way I could use the volume and tone controls on the piezo as well, but my intuition tells me that's not a good idea. Both pots are 250k Audio taper, and there's a .47 cap in there. This is the way it looks now: inabsentiadei.blogg.no/1266496539_gitarmodifiseringslog.htmlI'm using the ground side of the cap as ground bus. I'm thinking about putting the SPDT between the tone and the kill-switch. so. Any suggestions? I'm also going to add a 4pdt switch to add series/parralell functionalty as discussed in this thread: guitarnuts2.proboards.com/index.cgi?action=display&board=wiring&thread=4801&page=1But to do that I need to get my hands on a 4pdt switch, and I'm broke. Also, sorry about the kinda messy post.

Allmektig- Welcome Back! Just about everything you need to know about installing a piezo in a Strat can be found here, in JohnH's post on that subject: guitarnuts2.proboards.com/index.cgi?board=schem&action=display&thread=3718He suggests better results if a preamp/buffer circuit is used when mixing piezo and magnetic pups. Also, look at how he added mass (in the form of coins) to the piezo when mounting it to the "tremolo" block.

Thanks a bundle!
I'll read that thread, but I'm not sure about putting in a onboard preamp, since that would require routing of the guitar body.
I have the parts for the buffer circuit thoug, but I was thinking about putting it in an effect pedal, but I guess that means I cant mix the signals.
Anyways. I'll read that thread, and think about it.

Woha... That thread made my brain turn into mud...
But I can just remove the springs from the vibrato cavity, and stick in a piece of wood to block it?
The construction in that thread is a bit more complicated than what I had in mind... Actually, it's a LOT more complicated.
I'm also thinking about getting more of these piezo elements and make an acoustic pickup for my nieces western guitar.

Id suggest to wire up your piezo to a piece of shielded cord, run it into a stomp box as a buffer (eg any Boss pedal turned off), and just try the sound as you place it in various spots. Thats all I did, then followed my nose, and my ears, to end up with what I did.
