![]() Initially, it will be a passive piezo-only configuration, so I don't have to take blending with traditional pickups into account. Still, my main focus is to experiment with various placements and combinations of the piezos on the body and neck of an electric guitar.ītw, I am going to buy some pots for tone and volume control of the piezos. The latter was not a big success, as it picked up a terrible noise from the bow, but I imagine it can be filtered away. I've stuck it to a harmonica, an acoustic, an electric, a ukulele and a saw. I bought a simple acoustic piezo pickup a couple of weeks ago and I am just amazed at what you can do with it. I'll buy a selection of different piezos and give them a try. Thanks for the explanations and good points. I wonder what the resonant freq of a Ghost saddle is. They're cheap as dirt, so it doesn't hurt to get a few and mess with 'em. And I have no idea what one could tweek on a piezo (from a manufacturing standpoint) that would alter the resonant freq in one direction or another (I guess size and mass would be factors). Beyond that, I'm not sure how important frequency matching is, given the freqs that you'll play on a guitar are all over the place. This doesn't mean the piezo will give zero output at other frequencies outside the resonant frequency. In a way, this is sort of like measuring the frequency response of a pickup.there is a frequency at which the pickup's output is a maxiumum, and that is typically taken as the resonant frequency. There are links on the Digitech pages for specific piezo buzzers.įrom looking at some of these data sheets, it appears that the manufacturer defines resonant frequency as the frequency at which the impedence is a minimum. If anyone can give some advice helping me to choose wisely, I'd be grateful.ĭig a little deeper and for some of them, you can get PDFs of the datasheets (basically spec sheets) from the manufacturer. I expect the elements to vary in sound (that's part of the fun), but I'd rater avoid buying something completely useless. I want to order a selection of piezo elements of different size and characteristics. impedance or capacitance) of the piezo elements that should matter more in my choice? If so, what impedance or capacitance values should I go for? But since that is not available - at least not at a low price - would it be a good idea to choose the elements available with the lowest resonant frequency, even though they're still way higher than the frequency of the strings? I assume that the ideal choice would be a direct match in frequency. at Digi-Key), it strikes me that the resonant frequency of the elements is way above the frequency of the strings (the piezos often range between 1 and 5 KHz, and the strings are between 80 and 330 Hz). I intend to use them with traditional guitar amplifiers, perhaps with buffer/preamp. mounting on various places on the body, adding magnets for directly picking up string vibrations, etc. I am about to order some piezo elements for experiments, i.e.
