There are many differences and characteristics that every guitar is distinguished from another. Some features are highly visible, others are smaller and require more attention. If you do a serious investment, which is to buy the best guitar for beginners, it is important to base your decision to purchase on understanding.
If you are going to connect your guitar to a sound system or PA then you should think about the electronics that allows you to amplify your guitar. Sometimes it is in terms of the most cost effective to purchase a guitar, in which the electronics is already built. But some people want a specific type of element for their guitar and other than those installed by the luthier. So they will buy a guitar without any electronics then purchase a separate element, which then install it on their own, or they let the guitar shop to do it for them. There are a few different types of elements.
Electromagnetic sound hole elements
This is the most simple type guitar element and it fits, as the name implies, in the sound hole of your guitar. People want to use them much, because they tend to get fairly inexpensive, easy to install and there is no permanent installation or adjustment that your guitar needs.
The guitar element receives the movement of the strings by a magnetic field, which then is converted into sound, which can be amplified out of the guitar. Of all these elements, it is the most resistant to feedback (howling), which makes them very suitable if you work hard in live performances.
Some have the drawback that these elements are not quite capable of every nuance of the sound pick. There are some people who think that the elements look ugly because they were made in the sound hole, and usually runs a wire over the top of your guitar; unless you drill a hole in the back and connect it through the wire.
Microphone element gives you the most accurate representation of the original sound of your guitar; more than any other element. They capture the sound of the instrument directly and convert it into an electrical signal that can be amplified. The downside is that the feedback can be a huge problem if you’re on stage or in a setting with high ambient noise.
One way to reduce feedback, the microphone is attached in the guitar, closer to the sound source (the strings) but ultimately isolate from you so the microphone catches a smaller range of the sound source.
Dual source (Dual Source and Blender) element
Some mixing electronic systems (blend) like an internal microphone with an under-saddle element. Such a “blender” system allows you to control how much signal from the microphone goes to the output and the number of under-saddle element. Guitar Players who use this system often put the internal microphone just high enough to let the nuances of the guitar belong in the overall sound, and use the other element to ensure the majority of the sound. This allows you to avoid the possibility feedback and still use the internal microphone.
These systems can be quite expensive but many people will ensure that they are completely worth it if you seriously want to get the best sound from your best acoustic guitar. A few popular options for blender elements are the Fishman Ellipse Matrix Blend and the Fishman Rare Earth Blend Soundhole Pickup. However, a lot of people opt for a separate built-in or external microphone and for stronger element.
