best place to mount a piezo pick up?

Posted by Dave Breault on January 26, 2010 at 11:16am

Assume the neck of the guitar is glued to the under side of the lid, assume a neck through body construction, should the piezo be mounted to the under side of the lid or the bottom of the box?  Also should it be place towards the head or bridge?

 

Thanks for any insights offered.

    Time to start fretting, are they square, did I get them in the right place, will the glue hold, I can fret like this all day. Since this picture I've trimmed, sanded and test strung the guitar. Everythng seems ok, I did pop two off but that was no big deal to fix. I've named the guitar "Eater of Strings" I've broken 4 on it so far.

    Davd, Don't worry.... because it is so far from the "pivot" point where the neck enters the body, I doubt that this will be a problem at all... the best, Sam

    The new and improved location. I only hope I have enough meat left in the neck so as not to compremise the integrity, there can be a lot of stress right there I think.

    The smooth side facing the strings.... under the top than means directly against the underside of the top... if you put a piezo inside the bridge, the smooth side is direct against the bridge plate with the ceramic side in the void or outwards against the box opening.... then the ceramic side is encased in "cushioning" material....

    hope this helps,

    Sam, which side up should the peizo be, ie smooth side towards the strings or ceramic side, or dose it matter?

    Dave,

    That's a good plan... The idea of the silicone (or other cushioning material) encapsuling the back of the piezo is that this cuts down on feedback which is a problem with the back (ceramic) side of the piezo is left exposed....

    Oh, I know what I could do, what if after I get the piezo out of its pocket, couldn't I just continue drilling through the neck and stop when I reach the sound board, that'll be right below the bridge. Glue the element in there and then back fill the cavity with silicone, or would the silicone be necessary?

    Dave,

    Yes, since the piezo work by picking up the vibrations and since the top is the part of your CBG that vibrates the most in response to the strings (except maybe for the bridge), then direct contact with the top should yield the strongest volume response.

    We wanna see and hear the result....

    OK, so if I dig this one out and some how slide it between the sound board and neck I should get better results? It will be a trick but I have the tools and the technology, I can make it better, faster, stronger.
