Fret markers are typically located at specific intervals, such as the 3rd, 5th, 7th, 9th, 12th, 15th, 17th, 19th, 21st, & 24th frets, making it easier to find the fretboard without needing to count frets
The side markers are usually just dots, as are some of the fretboard markers. However there are also triangle designs, “sharktooth” designs, and over aesthetic inlays such as vines, bats, band logos, birds, and so on.
Fretboard
The fretboard, also known as the fingerboard, is a flat or slightly curved, usually wooden surface located on the front side of the guitar neck. It’s the playing surface that holds the frets & where the strings are pressed down to create different pitches.
The purpose of the fretboard is to provide a smooth and durable platform for the player’s fingers to navigate the neck and press the strings against the frets to produce specific notes and chords.
It is usually made from materials like rosewood or maple and is often adorned with fret markers or inlays as previously mentioned.
Pickups
Guitar pickups are essential to electric guitar anatomy and are devices located beneath the strings that convert string vibrations into electrical signals using magnets.
They come in two main types: single coils and humbucker pickups.
Single coil pickups have a bright and clear tone, providing a classic sound often associated with genres like blues and country.
Humbucker pickups offer a thicker and fuller tone with reduced noise, making them popular in genres like rock and metal.
The purpose of guitar pickups is to capture the electric guitar sound & transmit it to an amplifier, allowing for amplification and shaping of the instrument’s tone.
There’s also different positions for these such as the neck pickup, middle pickup, and finally the bridge pickup.
Pickguard
The pickguard is a protective plate, often made of plastic or other protective materials, that is placed on the body of the guitar, below the strings and around the pickups.
Its purpose is to safeguard the guitar’s body from scratches, dents, or other damage that may occur during playing, particularly from the strumming or picking motion.
