11/11/2023 0 Comments Piezo igniter wireWhen wired up in this way and plugged into an amp, the total volume output by the piezo will be controlled by the potentiometer. Tin your wires and don’t let the pot get too hot! Be careful when soldering to a pot though as it is possible to burn them out with too much heat. As mentioned above, pretty much any smaller-gauge copper wire can be used for this purpose, and shielded wire is not required. The other (black) is wired to the third contact of the pot and then on to the jack. Also, for piezo volume control, a resistance rating of either 250KOms or 500KOhms is recommended, with 500KOhms being the one most builders go with.Īs you can see from the diagram, one of the piezo leads (red) is wired to the first contact of the pot, and then continues off of the second contact and on to the jack. We recommend always using audio taper pots for volume controls, as they will give you a smoother rate of increase and decrease. There are two main types of potentiometers available on the market, identified by the type of their “taper” – audio taper, and linear taper. Really a pot is just a variable resistor that increases or decreases the total resistance as you turn it, which in turn allows more or less current through the circuit. This setup builds upon the concepts of the last diagram but adds one little twist – a volume potentiometer (pot) that allows you to control the output volume of the signal, in the same way that a volume knob on your stereo does.

One more thing – DON’T WASTE YOUR MONEY AT RADIO SHACK. Pretty much any kind of small-gauge copper wire will do – piezos do not require any special shielded wire or anything like that. The only other thing to note is that most piezos come with pretty short wire leads (in the range of 2 inches) that you will have to extend to reach your jack. With a straight piezo-to-jack it isn’t critical, but as wiring jobs get more complex it makes troubleshooting a LOT easier if you are consistent throughout! HOWEVER – it is a very good habit to always connect the ground (black wire) to the ground pole. The simple answer is that no, it doesn’t – you will get the same sound regardless of how you connect it. Or in other words, does it matter which pole on the jack you wire the red or black wire to. One question that gets asked a lot is whether the polarity of what piezo wire you connect to which pole on the jack matters. Many builders stick with this basic setup and never feel the need to get any fancier – and there is nothing wrong with that! This setup will give you a very straightforward sound, which is very dependent on where the piezo is placed and how it is mounted in the box – see our articles on piezo basics for more info on that. This is the setup that many first-time CBG builders use when looking to be able to plug their build into an amp. This diagram shows about the most basic wiring setup you can get: a single piezo transducer wired directly to a mono (two pole) jack. This can save you a lot of time, and time is money, so check it out! The Neutrik-brand jacks we sell in our web store are selected specifically because they have a nice 9.5mm shaft length perfect for getting through a cigar box side with a minimum of gouging and thinning. One more thing before we can get started – it can make things a LOT easier if you use a jack with a nice long threaded shank that will reach through the side of a cigar box. We will present three different diagrams here: a simple piezo to jack setup a piezo to jack with a volume pot added in piezos wired in series and parallel to a jack and a dual piezo setup that includes a 3-way switch for switching between the two piezos. You can get good results and have a lot of fun with something as simple as a piezo, a length of wire and a jack. Granted, you can get extremely complicated with it, but the point is you don’t HAVE to. It is important to remember that adding electronics to your CBG doesn’t have to be some kind of black magic. The basic concepts presented here can be built upon and experimented with in your own building adventures, with great results. In this article we will present several basic wiring diagrams created by Ted Crocker, and discuss each of them in some detail to help you understand what is going on.ĭon’t forget that you can get most of the parts shown in this article, including piezos, jacks, volume potentiometers and potentiometer knobs, right in our C. Putting electronic components into a cigar box guitar, and getting everything properly wired and connected, can be a daunting task for the first-timer – but it doesn’t have to be.
