Main Advantages of Tuning Machines and Their Accessories
In my earlier articles I discussed how tuning machines are operated. Here I am going to discuss how tuning machines work. A machine head is a specialized geared device for tuning various stringed musical instruments, primarily by adjusting guitar string tension. Machine heads are usually found on the underside of the instrument, on the headstock, and are used to increase or decrease the strings that are being tuned. There are two types of tuning machine heads: electromagnetic and hydraulic.
Electromagnetic tuning machines use electromagnetic induction to vary the pitch and type of signal produced by the spindle shaft. The advantage of these kinds of tuning machines is that they do not require mechanical parts to perform their operation. However, they generally do not have very nice tunes. The disadvantage is that the more number of tuning pegs that are used, the less control a guitarist can exert over the instrument. Although these tuning machines are often used for classical instruments, they can also be used to tune many other kinds of instruments including jazz, blues, folk, country, classical, pop, even metal. Some examples of popular tuning machines used in jazz bands are the tapered pegs and horseshoe pegs.
Hydraulic tuning machines are the opposite of the electromagnetic tuning machines. Instead of using electromagnetic induction to change the pitch and type of signal produced, hydraulic machines use hydraulic pistons to impart either pitch or type of signal. There are two types of hydraulic machine heads to choose from: drum-type and tapered types. The most common tuning machines that use hydraulics are the tapered pegs and horseshoe pegs. These two types of machine heads have different designs that make them suitable for various purposes.
Treadmills have gears on both the top and bottom, but unlike with the other machines, there are two main categories of tuners: open wound and closed wound. A good example of an open wound tuner is the GTRT (general trip type) which has one wound drum piece and two wound on the top and bottom. A good example of a closed wound tuner is the MTBT (Matched Transfer) which has one wound drum piece and two wound on both sides.
The three types of machine heads that you can choose from are: sealed tuning pegs, sealed gear system, and open wound. In sealed tuning pegs, the top and bottom of the drum are both covered with the same grease so that when the top and bottom are pressed together, the inner groove on both sides will engage with each other and the groove will push the gears into one another. The sealed pegs allow for easier adjustment than the other two gears systems. In the sealed gear system, you only need to replace the top and bottom gears in order to change the tension of the machine. However, the sealed gear system does not allow you to make adjustments to the length of the teeth since it only allows for relatively small adjustments.
The gears in the sealed gear system allow for easy adjustments. Aside from just a few adjustments, the gears in the gear system allow for a larger range of gears that will be able to get the job done in a more efficient manner. Another main advantage of the gear system is that it offers a better and more secure protection against debris and other kinds of harmful particles.
The sealed machine peg is where you place your finger when you place the tuning peg on the neck of the drum. This is the part of the drum that you will strike to change the tension of the drum. The open-wound type of drum gear has no gears to engage or disengage. It works like this because the strings on the guitar have tiny teeth that are wrapped around the rubber or metal gears. If you apply pressure on both sides of the string at the same time, these teeth will engage with each other and produce a whirling sound. It is like a small tornado that will quickly move towards its destination.
When these two types of gears are combined, the result is what you will hear as your musical instrument vibrates in tune. However, with tuning pegs, there is less chance for the strings to slip out of place. The tuning pegs do not have teeth that can be easily removed. Also, with this equipment, the guitar's intonation can be easily adjusted and maintained as well.
