![]() I’ll get into some more detail later - properties of different types, problems, installation, etc. ![]() That’s the basics of how piezo pickups work and the important bit about how you say it. That’s nice long vowel sounds all ‘round. However, Merriam-Webster recommends the following (and most people seem to have settled there): While both primary electric guitar pickups are magnetic, meaning. I’ve heard (and used) a number of different pronunciations over the years. Acoustic guitar pickups, however, are a completely different beast, as most use a piezo pickup. IMG The big question: How to pronounce ‘piezo’ The vibrations from the guitar top are transferred to the piezo element and turned into lovely electricity A thin piezoelectric element is glued to a thin metal (usually brass or similar) disc. The construction of these is pretty simple. Instead of getting those vibrations transferred through the saddle material, this pickup is fixed or adhered to the guitar soundboard/top. The principal is mostly the same as with other pickups - turn vibrations into electricity. We know about undersaddle transducers (pickups) so let’s take a whistle-stop tour of the other application of piezo technology that’s relevant to the musician: soundboard transducers. A preamp drops the impedance from the piezos millions of ohms to a more reasonable thousands of ohms. Which brings me to… Piezo soundboard transducers Piezo pickups have an impedance ranging in the millions of ohms, meaning that a long wire coming out of a non-preamped piezo can turn microphonic and create harsh noise when the wire is moved. Finally, in the miked acoustic guitar spectrum, there’s a bit more energy in the. Also, the piezo pickup’s high frequencies are more pronounced because piezo pickups tend to have a natural brightness. Likewise, a piezo pickup also converts vibrating string energy into electricity (the only difference is how that string energy gets transduced). The acoustic guitar piezo pickup not only misses the bump’s peak, but the frequency response extends much lower, giving a boomy sound. So, for instance, a magnetic pickup in an electric guitar converts vibrating string energy into electricity. You might have seen undersaddle pickups called Undersaddle Transducers (abbreviated to UST).Ī transducer is any device that converts one form of energy into another. Again, more details in the future but, for now, I’ll point you at an article where I discuss one of the most important aspects - string break angle. The hugely important thing to remember about piezo undersaddle pickups is that they won’t function well without effective transfer of those string vibrations. A piezo pick up works differently and can be placed on the head-stock of any stringed instrument including violins and cellos, and will transfer the. There’s a separate piezo element for each string (although the signals from each all run ‘together’ - there’s only one signal path to the amp). The copper strip is the ‘positive’ conductor and the housing channel forms the negative conductor. Like I say, it’s pretty simplified but it does the trick.
