It is not as sensitive as a magnetic pickup, but it has a very wide frequency response with no large standing waves. What is a Piezo Pickup?Ī piezo pickup is a type of electric guitar pickup that produces a volume and tone characteristic different from those of magnetic pickups. You can install a piezo pickup on an electric guitar using these steps: Remove the strings from the guitar, unscrew the bridge and remove the old pick up, attach the new pick up to the bridge by drilling holes into each side of it and insert screws to secure it tightly against the bridge and screw back on the bridge and replace the strings. Piezo pick-ups are not as sensitive as magnetic pickups and will not work as well with acoustic guitars. Pick up must be installed to soundboard for best sound. Finally, screw back on the bridge and replace the strings. Then you will attach the new pick-up to the bridge by drilling holes into each side of it and insert screws to secure it tightly against the bridge. You’ll also need to remove the strings from your guitar, unscrew the bridge and remove the old pick up. First, you’ll need some basic tools like a screwdriver and some screws. It may take some time to make sure the piezo pickup is properly attached to the bridge, but it’s simple. Installing a piezo pickup on an electric guitar is not hard.

Then unscrew the bridge and remove the old pick up. The first step is to remove the strings from the guitar. In this article, we’ll take a look at the steps to install a pick-up on an electric guitar. The question on how to install piezo pickup on electric guitar is answered here. ![]() If you use a lower input resistance amplifier, you'll need to pad the output of the transducer with a capacitor to flatten the low frequency response which will cause a loss in amplitude response.A piezo pickup is a type of electric guitar pickup that produces a volume and tone characteristic different from those of magnetic pickups. Plus, making a step down transformer with a 100:1 impedance ratio (10:1 voltage ratio) will attenuate the signal which will degrade the signal to noise ratio (not good).Ĭonclusion: Stick with the preamp approach and use a preamp with an input impedance above 6.4 M \$\Omega\$. The magnetizing inductance calls for a primary inductance over 20k Henrys (magnetizing inductive reactance needs to be a few times higher than the transducer impedance). Using a transformer at this high impedance is not practical. Assuming you want a low-cut frequency of 50 Hz, Rin would need to be 6.4 Megohms \$ (1/(2 \pi\ f\ C) = 1/(2\pi\ 50Hz\ 500pF)) \$. ![]() ![]() Higher Rin will make the high-pass cutoff frequency lower and will also lower the input noise. The amplifier input impedance will determine the low frequency response of the system and also equivalent input thermal noise. Simulate this circuit – Schematic created using CircuitLab I couldn't find electrical data on piezo guitar pickups, but one source said the simple capacitance of typical guitar piezo pickup is around 500pF to 800pF. Near resonance (one source said around 4.6 kHz), the impedance is complex and the amplitude response will peak. At low frequency, a piezo transducer can be modeled as a capacitor and a voltage source as shown in the schematic.
