My takeaway is that a piezo saddle or bridge makes much more sense than I realized. One surprising thing is that placing at the saddle doesn’t sacrifice the deep tone I wanted the way a bridge magnetic pickup does, since the piezo is not reacting to the strings like a magnetic pickup does. I had to experiment for an hour to figure that out, now I have to work out a way to mount it that way. I guess it’s the different vibrations between the different surfaces that greatly increases the vibration in the piezo and the effect is a really nice almost upright sound. The housing has four posts that form the clamp and what works for me is to place two posts against the bridge/saddle and two on the body. Mine is permanently glued into a metal housing that is meant to clamp onto the bridge of an upright. They can be used as pickups for various musical instruments, such as acoustic guitars, violins, cellos, double-bass (aka upright bass), ukuleles and mandolins (etc.), and also as accelerometers. It will sound weak and tinny but you shift it a half inch over and it sounds worlds better. Introduction Piezo transducers are common in a range of different areas. The variation in sound between one location and another is dramatic. What I have learned is that the placement of the piezo is crucial. The mudbucker pickup doesn’t capture that sound well so I got a piezo and a buffer/preamp designed for an upright. I have an old Japanese eb-2 clone and with tapewound strings it comes closer to an upright sound than I’d have predicted. If you are planning on installing a piezo bass bridge, you probably have questions about the electronics, some of which may specifically be around grounding. But of course they used a proprietary “dovetail” wooden bridge along with specialized construction.Ĭould you get a sound like this on your fretless electric bass? You can – even on a plain solid-body – but it is suggested that in addition to the piezo bass bridge you use tapewound strings (although stainless steel flatwounds could be used), and learning basic upright playing techniques also helps out quite a bit. When attempting to get that sound out of an electric bass, yes it can be done, but it takes the right hardware to do it.īelow you will see a video of the Veillette Paris model bass, which does have a convincing upright bass sound. When you want that low, boomy-in-a-good-way sound, you need a big acoustic bass to do it with. The best way to answer that is to say first that nothing sounds like a real upright bass. ARTEC bass piezo pickup PP 437, bass 4, maximal 57mm, -Specifications: ARTEC Piezo Pickups are made by Piezoelectric material piezo ceramic that has shown. Is the piezo pickup the “secret” to the upright bass sound? Those pickups can be quite expensive if you buy them at. We also mentioned that we carry piezo bass bridges. Here Id like to share my version of a piezo-pickup for a double bass (and most other instruments). a 25V part is perfectly fine.ĥ) This particular preamp (an FET source follower) can handle quite a big signal without distorting, so it shouldn't be bothered by the fact that your pickup is "hot".In a recent article we featured an Ibanez fretted/fretless hybrid where the fretless part of the bass has a piezo pickup. Doesn't matter if it's considerably more than 9V, i.e. It needs to be rated for well over 9 volts.

The original value of 4.7uF is a bit stingy, and a 47uF cap is still very cheap. (But be kind to your amp and speakers - plug in everything, keep the amp off, power up the preamp, wait a few seconds, then turn on the amp.)Ĥ) I increased the preamps power supply filter cap to 47uF.

This will reduce thumps and bangs if you plug your preamp into the input of an amplifier that's already turned on.

If you still have enough signal level with the added cap, you don't need to build a preamp at all!ģ) If adding a 4.7 nF cap kills signal too much, and you do build the preamp, it's important to add an additional resistor from output to ground (R4 in the schematic attached to this post). Lacking this, I can't tell you exactly how much the output will be reduced by adding the 100pF cap.Ģ) Since your pickup is already "hot", try connecting a 4.7 nF (same as 4700 pF) capacitor between pickup output and ground it will reduce the output signal, but it will also make the pickup compatible with a 1-megohm amplifier input impedance. Id do a search here on talkbass since this has been asked by a ton of people (including myself). Unfortunately, the manufacturer of your Copperhead does not seem to provide the one specification we need: the actual capacitance of the pickup. Thats not the type of piezo you want for a bass. Here's a cleaned up circuit, stripped of the stuff you don't need.ġ) If you add a 100pF cap across the input, it will reduce the output voltage from your piezo pickup.
