Components
Electric guitar bodies use some of the same woods found in acoustic guitars, such as mahogany; maple; rosewood and ebony.
But electric guitars often use other woods, such as alder, ash, poplar, or basswood. Contrary to what you might believe, the type of wood used in an electric guitar dramatically affects the sound (as well as weight) of an electric guitar.
In general, maple, ash, and alder have a bright sound, whereas mahogany has a lower, rounder tone. Since electric guitars do not require the soundboard that acoustic guitars require, spruce is seldom found on electric guitars
.A guitar bridge provides an anchor point for the guitar strings, and it should provide the correct string "break angle" so the strings can vibrate freely without buzzing.
If the bridge is set too low then strumming the strings could result in the strings hitting the frets while the guitar is being played.
A few electric guitars have a bridge that is similar to those found on acoustic guitars. However, many electric guitars separate the bridge and tailpiece (the string anchor) into 2 pieces for a clearer sounding instrument. Also, many electric guitars have an adjustable bridge piece for each string, to enhance adjustability. A poorly installed, or poorly adjusted bridge will have poor intonation.
.This is the input jack and the standard size is 1/4" jack.
Some jacks have a release mechanism so that cord will not become accidently unplugged while playing. An inexpensive guitar will have an inexpensive input jack that may fail and need replacement. . . . .The nut lives at the top of the guitar neck.
It provides a separate channel (slot) for each guitar string, and provides the string "break angle" so the strings can vibrate without buzzing, and without the hitting the frets while the guitar is being played.
Traditionally, guitar nuts were made of bone, usually the horn of an animal. But a guitar nut made of bone requires genuine skill to carve accurately. A poorly crafted nut could pinch the strings and thereby affect tuning, or conversely cause them to rattle and buzz while playing. Most modern guitars have a nut made of plastic or metal to improve the consistency of the guitar nut.
. .Pickups consist of a magnet with a coil of wire wrapped around it.
When you plug your electric guitar into an amplifier, it applies a small voltage to the pickup wire. This creates a magnetic field around the guitar's pickups.
Strumming the guitar strings (which are made of nickel and stainless steel) interrupts the magnetic field the pickups create, and this is the signal that gets amplified by your guitar amplifier.
. .Potentiometers (pots) are variable resistors.
In electric guitars, they are used as volume and tone controls. An inexpensive guitar might have inexpensive pots that may become scratchy sounding, or fail completely at some point
. . .Tuners are used to anchor and tune the guitar strings.
Nowadays some tuners are locking tuners, where you can lock down the tuner to ensure minimal slippage of the strings while playing.
Having to tune up frequently because of poor quality tuners is a nuisance to be avoided!
A more expensive guitar will have better quality tuners.
