    I am trying to build my own music instrument pickup and I need some help! I first am looking at piezo sensors but had some questions... Do I have to make sure that the piezo sensor picks up the entire frequency range of my instrument? I can't seem to find any sensor that has a large enough range.. do you guys have any suggestions on what to buy...? I want it to be great quality so I don't just want to slap on a ceramic disk piezo and be done... Thanks!

    I'm no expert but I have built a cigar bax guitar utilizing a piezo element. From my expierience it picks up any and all vibrations including the handling of the instument. If you want seperation of frequencies using a piezo element then that will have to be done through a circuitboard.

    A piezo transducer has many higher frequency peaks (resonances) and nulls and makes a very poor sound or vibration sensor. It has poor low frequency response.
