The majority of car stereos in North American cars come equipped with a tuner pedal. However, it is possible for car owners to install their own tuners. This process is often referred to as "DIY Tuner." When installing your own tuner you have several options. Some car stereo systems come with a stock tuner, which means that you do not need to purchase any additional hardware. Most systems will also allow you to choose from many different pre-installed tuners.
While each unit differs in function, they all operate on the same general idea. All car tuners are used to send a different channel into your head unit so that you can hear your music without having to play it through your speakers. Some tuners will have two channels, called a mono input and a mono output. While each channel will serve a specific purpose, in most cases the two channels will be used to achieve what we call a bypass mode.
There are basically two ways to use your guitar tuner pedal: in the "on" position or in the "off" position. In order to play your music through your head unit in the "on" position, you should turn the pedalboard counterclockwise. To change the pitch of your music you must move the pedalboard up or down. There is generally a control knob on the top of the pedalboard which allows you to change this operation.
Before getting started it is important to understand how your electric guitar tuner pedal works. You start by turning the actual pedalboard arm in clockwise (tune one). This causes the actual tuning mechanism to open, thus allowing the strings to strike the fret board. You then use your fingers to do the same action in anti-clockwise fashion, thus closing the tuning mechanism.
You may think that the process is similar to tuning your drums, but there are a few key differences. For starters, an acoustic guitar player will not be able to adjust the pitch of his/her strings using his/her pedalboard. The reason is that the acoustic guitars tend to have open strings. Tuning your guitars using your tuners requires the presence of another instrument. This other instrument is known as a tuner (also known as a head or a foot pedal). A tuner usually sits between the electric guitar player's thumb and fingers and is used to compress the sound of the strings.
A chromatic tuner pedal is the simplest and cheapest way to change the pitch of your tune. It uses six different tuning modes, which can be accessed by pressing different keys on the pedal. These 6 modes enable you to change the pitch B flat to A flat, C to D flat to E flat, F to G, H to A and J to K (or any note that's half way between a natural tone and a sharp one). The difference between these six modes is the length of each mode. While a mode with a shorter duration will produce a pitch a half-tone higher than natural tones, a mode with a longer duration will produce a pitch half-way between a natural and sharp tone. So if you want to play songs with a certain tempo you should use a long-tone tuner pedal.
Another very popular tuner pedal is the Boss TU-3. The Boss TU-3 is also called the "tune-shaker" because it enables you to listen to a song without even playing it. To use this popular tuner pedal all you need do is turn it on and place your fingers over the fret you want to tune to, while you hold the other fingers flat against the fret you are not supposed to touch. If you do this properly the notes will be clearly audible.
In addition to the above pedals, you might also want to look into the following: Korg PitchBlack chromatic tuner pedal, Yamaha CS-series analog tuner pedal, Fender Stratocaster vintage model tuner pedal and other models that are similar to them. If you want a really cool looking pedal try a Boss RC-series tuner pedal. These models are actually made in the same factory as the famous Fender Toastmaster. It is called the Boss Time delay/time distortion pedal.
