Best Guitar Tuner — Buyer’s Guide

These are some of the best guitar tuners that you can find with a good mix of features and price.

Given the variety of products on the market, it is understandably easy to get lost. To make sure that you will buy the right product, you will have to consider the following points:

Price. Look through the offerings and land on the amount of money you can spend. It should be somewhere in the middle of what you’re comfortable with paying and what vendors charge for quality products.

Tuner type. There are two major types of guitar tuners — pedals and clip-ons. Pedals and mounted on the pedalboard with the rest of your effects setup, while clip-ons are usually installed on the headstock or the deck of the guitar.

Features. Make sure that the tuner you choose has everything you need. You may find the additional features such as a metronome useful, or just stick to the barebones tuning. Take a look at the build of the device to see if it is sturdy enough, if there’s any power supply in the box, or if there’s a true bypass feature.

Do not get carried away with stuff you don’t want or need — you may end up overspending. Just focus on the essentials.

Where should I place a guitar tuner in the sound chain?

To properly tune your guitar, the tuner must use a clean, unprocessed sound. Therefore, it is better to place the tuner at the beginning of the sound chain. Keep in mind that not all guitar tuners are true bypasses. Therefore, after tuning the guitar, such tuners should be removed from the chain.

How to tune the bass guitar properly with the tuner?

The bass guitar has an E-A-D-G fret pattern. In order to correctly build the frets on the bass guitar, it is enough to switch the tuner to the “chromatic” mode and use the bridge pins to achieve the desired sound.

Is it possible to use a standard tuner to tune the ukulele?

Yes. Ukuleles use the G-C-E-A or D-G-B-E fret pattern. Such patterns are supported by most tuners. More than this, you can tune the ukulele using just a mobile app.

Is it possible to use the tuner as a mute pedal?

It depends on the presence or absence of a true bypass option. Some pedals without the true bypass mode without the power supply kill the sound. But there is no such inbuilt possibility in most guitar tuners.

What are the main differences between the KLIQ TinyTune and the Pro version of this tuner?

The Pro version differs from the standard one by the presence of additional options. First of all, the manufacturer pays attention to more precise tuning using the KLIQ TinyTune Pro. Also, the more expensive version has a better display, which makes it comfortable to use the device in any light. True bypass is also a feature of the Pro version. As for the tuning of the guitar itself, the frequency range in which you can tune is larger in case of the Pro version. The most useful option of the Pro version is the presence of the device memory, which will allow you to save the settings after the power is turned off.

All tuners go without the power adapter. What power adapter is needed?

Almost all tuners require a 9V power adapter. They can be found at any music store or ordered from Amazon. We recommend using power adapters from “Digipartspower”, “Belker” or “Zozo”.

Is an octave or a note displayed on the tuner display during tuning?

While tuning the guitar, the display shows the note that is currently being played by the guitar string. In order to tune your guitar correctly, you need to know the correct pitch of each string and tune each string to the correct note.

How does a tuner connected to the sound chain affect the sound?

A tuner in the sound chain should not have any effect on the sound. Sometimes cheap tuners cause audio interference.

Is it possible to use my headphones with 1/4″ jack to tune the guitar or do I only need to use an amplifier?

Yes. It is possible to connect and get the sound from the tuner output but it will go in mono. To make it stereo you’ll need a special cable.

Is there a preset frequency or it could be adjusted?

In most tuners you can adjust the frequencies. But the operating mods are preset.
