There are a lot more different guitar types than the usual acoustic and electric models that come to most people’s minds. The guitar has evolved in such a way that many different variations have been made. Some of these types of guitars are very interesting and they vary based on their design, sound produced, and playing techniques. There are certainly a number of different types of guitars out there.
1. Acoustic Guitar
This is the most common type, the one we picture in our head when someone mentions the word guitar. It is present in almost every genre of popular music and even though there are some variations regarding shape, all of them are characterized by steel strings and the same group of tonewoods that are used.
All acoustic guitars work in the same way. Once one of the strings is plucked, the string vibration goes through the bridge to the top, side, and back wood of the body, and then resonates through the air inside the body, making the sound.
Acoustic guitars are usually made from tonewoods like spruce, mahogany, ebony, etc. Of course, each material uniquely impacts the sound but, generally, acoustic guitars are characterized by bright and precise tone, especially in higher frequencies.
There are different types of acoustic guitars, regarding body shape. Some of the most common are dreadnought, double-O, grand auditorium, etc.
2. Classical Guitar
Throughout history, numerous string instruments looked similar, but a classical guitar is the first one that came with a shape that is typical for today’s guitars. It dates from the 19th century and features a few important differences compared to acoustic guitars.
The first thing you’ll notice is the string material. While acoustic guitars are steel string guitars, a modern classical guitar features nylon strings (natural materials were used in the past). As a result, the tone is notably different. While acoustic guitars sound bright and sharp, classical guitars sound soft and mellow.
Another big difference is in the fretboard design. Classical guitars feature wider fretboards, which work better for techniques like fingerpicking. On the other hand, an acoustic guitar is more about strumming and playing with a pick. When it comes to tonewoods, tops are usually made from mahogany, spruce, cedar, maple, etc. The back and sides are usually made from rosewood, mahogany, maple, Hawaiian koa, etc.
3. Electric Guitar
The first electric guitars appeared in the first half of the 20th century and compared to acoustic and classical guitars, they can’t produce a sound that’s loud enough to be played without an amplifier. Originally, electric guitars were designed for jazz players and the reason is quite obvious. In a big band full of brass instruments, it’s impossible to be loud enough with an acoustic guitar, especially when you play a single-note solo. So, amplification was the solution.
The way electric guitar works is different compared to acoustic guitars. The body is made from a solid piece of wood, so there is no resonator box. Instead, string vibrations are picked up by pickups, which turn the sound into an electrical signal, which is reproduced as sound by loudspeakers.
Electric guitars are also characterized by thin and comfortable necks, which allow unparalleled playability, especially for single-note soloing. As you may presume, there are numerous types of electric guitars out there.
4. Electro-Acoustic Guitar
Commonly known as acoustic-electric guitars, this guitar type is somewhere halfway between acoustic and electric guitars. The overall design is pretty much the same as on acoustic guitars. However, they also feature pickups, which allows them to be much louder.
The general idea of an electro-acoustic guitar is to sound like an acoustic guitar but louder. Without an amp, these guitars sound the same as acoustic guitars. On the other hand, the amplified sound can be altered in many ways, with effects like reverb, delay, chorus, etc. However, distortion doesn’t sound very good, because of too much feedback that comes from its highly-resonating body.
5. Twelve-String Guitar
A twelve-string guitar is a guitar that features twelve strings instead of six. The tuning is the same as in a 6-string guitar, with two strings for each note. That provides a far more powerful tone.
Also, lower strings are usually tuned in octaves. So, there is a combination of thicker and thinner strings for each note. The thickness difference causes different vibrations, which produces a natural chorus effect, which is probably the most authentic thing about a twelve-string guitar.
