GuitarTuna Screenshot - the most downloaded tuning app in the world.


One of the first things that any aspiring bass player learns to do is to properly tune their instrument. Typically a beginner doesn’t yet have the skills needed to tune their instrument by ear, training skills needed to tune accurately, and that’s where a good bass tuner comes in handy.

One of the best bass guitar tuners available today can be found in the GuitarTuna app. Featuring some of the most advanced technology available today, tuning your bass has never been easier – and you can do it right from your smartphone (Android and iOS platforms are supported).

Free Bass Tuner App

If you go online or make a visit to your local music store, you’ll typically find a wide range of tuners that will tune either bass or guitar. Some work great, and others…well, not so much. They all have one thing in common though – you can’t walk out of the store with one (or get one delivered to your home) without placing an order…

You know what that means, right? It means having to part with some of your hard-earned cash! Prices can range from $10 up to over ten times that amount for a tuner with acceptable quality.

Here is where we have a great advantage – you can download our bass guitar tuner app absolutely free! Many other bass tuner apps will charge you as well, but you will always be able to get our online bass tuner without paying a single penny!

How to Use Our Bass Guitar Tuner App

There are no instrument cables needed with our bass tuner, as it conveniently uses the mic and the speakers in your smartphone (we do recommend using a bass amp for maximum accuracy).

The first step is to download our bass tuning app and select bass as your instrument You can choose the ‘standard’ or another tuning depending on your preference and the songs you want to play.

Our bass tuner has two operating modes: Manual and Auto. Manual mode allows you to choose which string you want to tune. Auto mode is even easier – with the Auto mode, all you have to do is play a string, and our app will automatically determine what string you are trying to tune. You’ll see a small indicator right above the picture of the instrument headstock. As you adjust the tension on the string by turning the tuning pegs, the indicator will move on the screen, telling you if the pitch is too high or too low. Once the indicator reaches the middle of the screen, the string is in tune.

Bass Tuning Quality

You may have tried using tuner apps before but have been less than happy with how they worked. In our experience, many of these apps are not very accurate. The tuning indicator can bounce all over the place and be very erratic. That’s incredibly frustrating – it not only takes longer for you to tune up, but you’ll find yourself questioning how correct your tuning actually is.

This is all due to the quality of the signal recognition engine that drives a tuner app. With the bass tuning app found in GuitarTuna, that will never be a concern! That’s because we use the exact same, ‘world’s best’ audio algorithm that powers the well-respected Yousician app. You’ll find that the tuning indicator will be rock solid, and the pitch recognition is extremely accurate.


How to Tune a Bass Guitar

Tuning a bass guitar is a fairly straightforward process, and it is one that you should do every time that you pick up your instrument. There’s nothing more terrible sounding than a bass that is out of tune!

Tuning is a process where you change the tension on the strings in order to have them produce the correct note. Typically you would start by tuning up the lowest (thickest) string. Using our bass tuner app (especially in Auto mode) you will easily be able to tell how far out of tune you are. If your note is flat (the pitch being played is lower than the correct note), then you would add tension to the string by tightening the tuning machine on the headstock. The opposite is true if your note is sharp, where the note is higher than needed. In this case, you would decrease the tension until it’s just right.

Most bass guitars are set up for ‘standard’ tuning. Alternate tunings can be used as your playing skills and understanding of music theory progresses, but ‘standard’ tuning is the most common way to tune.

Looking at your bass strings from low to high, you will be tuning to these notes:

• Fourth (thickest) string: E
• Third string: A
• Second string: D
• First string (thinnest): G

Our bass tuner is just one part of what you’ll get when you download GuitarTuna – you’ll also find an easy-to-use metronome to keep time while you practice as well. With an incredible bass tuner and other additional features, why wait? Download the GuitarTuna app today!
