Best Guitar Tuners Buying Guide

best guitar tuner buying guide

As much as some guitarists have a perfect pitch, having the best guitar tuners is necessary. You’ll need it to confirm that every string sounds at it should work during a performance, during practice.

Many people have a problem choosing guitar tuners today. Why? Because there’s a whole lot of guitar tuners to choose. They come at different sizes, shapes, designs, and prices. And all of them promise one thing, accuracy.

If you are looking for a guitar tuner, this buying guide is for you. By the end of the article, you should know how these tuners work, and how to choose the best one for your needs.

How do these devices work?

The first thing to know is how a guitar tuner works. Primarily, all guitar tuners are set to tune specific instruments. Every tuner comes with a display screen and a meter that shows the string you are tuning, and how close you are to the right tone.

Besides that, tuners can either be electronic or use forklifts. Electronic tuners detect the tone of the string in two ways. They can either use a microphone; detect vibration, or use a mix of both. Forklifts use vibrations to detect whether a string is in tune or not.

Types of tuners:

As mentioned earlier, tuners come in a variety of sizes and shapes. When you start shopping, you’ll come across a variety of options. The most common ones include:

–         Chromatic and non-chromatic tuners

Chromatic tuners normally allow the guitarists to tune the guitar to 12 pitches. They are ideal for any instrument that has six or more strings on them. Non-chromatic, on the other hand, will only allow you to tune the guitar to up to six pitches. Hence, it’s appropriate for instruments with six strings or less.

–         Headstock tuners

These tuners are common for acoustic tuners, but they can also tune electronic guitars. When tuning, the player has to attach it on the guitar’s headstock.

–         Pedal tuners

Pedal tuners operate like any other pedal. You attach it to a pedalboard and operate it via a battery or a power adapter. You can switch these tuners on and off using your feet during a performance.

–         Tabletop tuners

They can be huge tuners, which you can place on top of your table. Most of them have a small microphone installed to detect the string’s frequencies.

–         Rack and pre-amp tuners

These might not be so familiar for beginners. You’ll find these two types of tuners in studios, especially the rack tuners. Pre-amp ones come as an additional feature in a guitar amplifier.

–         Phone apps

A new breed of players prefers using smartphone apps to tune their guitars. These types of tuners depend on smartphone microphones to tune the strings. Still, they can be inaccurate, especially in noisy environments and because the phone’s microphone is not built to tune guitars.

Choosing the best tuners

Before you say that buying the best guitar tuner is not worth it, it’s good to remind you that not having one can be disastrous. It’s worth the investment, and if you find one that suits your needs, you’ll never have problems with tone during performances.

When choosing, here are some of the things to consider.

  1. Price

It’s not a priority; nonetheless, you should keep in mind that these devices come at different prices. And it’s upon you to decide how much money you want to use on your guitar tuner.

However, do not think that lower-priced tuners are not worth it. Some can be a huge bargain, especially if they offer accurate tuning. Therefore, the best way around this is to check out different reviews to see what other users say about the tuners.

  1. The instrument you are tuning

All stringed instruments need to be tuned before you start playing. Manufacturers build tuners with specific instruments in mind. Therefore, if your guitar has more than six strings, consider going for a tuner that can tune such instruments.

Besides that, it’s also advisable that if you are a guitarist that uses a different tuning other than the standard tuning, going for one that can adapt to that is vital. If you are also using a capo, you should also consider a tuner that can adapt to this.

  1. Features that it comes with

Primarily, what we mean here is that the tuner should be easy to use. You shouldn’t have problems using it. The display should be easy to see, especially in a dark lit room.

If possible, you should check whether the tuner comes with extra features such as a metronome, which students can find useful.

Remember that tuners come in different sizes and shapes. So if you want a pedal tuner, it should fit into your rig perfectly. And if you want a guitar tuner that you can carry everywhere you go, consider the size.

  1. Accuracy of tuning

This might be the most crucial aspect of all. If the tuner is not accurate in tuning, your instrument will sound awful. We found out that most tuning should have a margin of error between +/-1 to +/-3 cents, which is the tuning accuracy unit. Tuners with lower margins of error are the best.

Most apps have a problem with tuning inaccurately. Therefore, you scrutinize their tuning mechanisms before you pay for any subscriptions or before you use any.

Buying the best guitar tuners isn’t an easy task. On the other hand, if you take your time to understand how each works, you’ll make a sound decision when making the purchase. It’s also advisable to ask for recommendations from friends and experts. Read as many reviews as possible so that you can know what suits your needs. At the end of the day, it draws down to your needs.

Final Remarks

As you can see, all these best guitar tuners come in different shapes, sizes, and designs. We want to urge you to focus on the purpose of the device rather than how it looks. The guitar tuner you choose should tune the string instrument you are using or even more than one string instrument. It should also come with different tuning settings to suit different musical needs, for playing jazz or classical music.

In our opinion, the BOSS TU-3 Tuner is the best buy option. The guitar pedal comes with modern enhancements, which make it easy to tune any guitar. We also liked it since it can fit into any pedalboard, doesn’t consume much space, and has a true bypass/buffer switch to suit different tuning needs. Furthermore, it comes at an affordable price. Any guitarist would do anything to have this pedal in their rig.
