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

Fortunately for all beginners and more experienced bassists, one of the best bass guitar tuners 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 (available for Android and iOS).

Free online bass tuner app

If you go online or visit your local music store, you’ll typically find a wide range of tuners that will tune either bass or guitar. Some work great, but you might run into some issues with others. All bass tuners have one thing in common, though – you can’t walk out of the store with one (or get one delivered to your home) without investing some of your hard-earned money. Prices for tuners that are compatible with a bass guitar can range from $10 to over ten times that amount, if you want a tuner with acceptable quality.

Here’s where we have a great advantage – you can download our bass guitar tuner app absolutely free. Like all physical tuner devices, some other online bass tuners will charge you as well. Luckily, you’ll 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 cables needed with our bass tuner to get your instrument tuned, as the app 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’ E A D G tuning or one of the alternative tunings 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 and you can switch between different strings manually. Auto mode is even easier – with the Auto mode, all you have to do is play an open 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 moves 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 some other online tuner apps before but have been less than happy with how they worked. In our experience, many other apps aren’t always accurate and the app’s tuning indicator can be unpredictable. That makes getting all four strings of the bass in tune difficult and frustrating. Fortunately you won’t have this problem with our tuner app, because getting your bass in tune is both fast and simple. With GuitarTuna, you don’t have to question whether the instrument is in tune or not.

Thanks to the high-quality signal recognition engine that drives the bass tuning app found in GuitarTuna, getting your instrument in tune doesn’t have to be a struggle. That’s because we use the exact same ‘world’s best’ audio algorithm that powers the Yousician app. You’ll find that the tuning indicator will be rock solid and the pitch recognition extremely accurate.


How to Tune a Bass Guitar

Tuning a bass guitar is a fairly straightforward process, and it’s one that you should do every time you pick up your instrument. Nothing makes playing the bass less fun than using an instrument that’s out of tune.

Tuning is a process where you change the tension of the strings in order to have them produce the correct note. Typically you start the tuning process by tuning up the lowest (thickest) string. Using our bass tuner app (especially in Auto mode) you can tell easily how far from the correct tune you are. If your note is flat (the pitch being played is lower than the correct note), then you have to add tension to the string by tightening the tuning machine on the instrument’s headstock. The opposite is true if your note is sharp, where the note is higher than needed. In this case, you 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. However, ‘standard’ tuning is the most common way to tune and one you’ll hear being used in most songs.

Tuning your bass to E A D G

When looking at a 4-string bass from low to high, you’ll be tuning to these notes:

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

Our online 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 as you practice. With an incredible bass tuner and other additional features, why wait? Download the GuitarTuna app today and get your instrument in tune.
