There was a time when Fender was known for its exquisite guitars and amps. The amps were designed to further enhance the sound quality of the Fender’s guitars.

Unlike guitars, these do not have strings or necks, but they do are available in a different color, size, and shape similar to the guitars.

It is equally important to choose the right amplifier as it is necessary to pick the right guitar. In this Fender Rumble 40 review, we would discuss if the product is worth your money and attention.

The bass sound that the amplifier produces is worthy of quite some attention. The product brings a lot of excitement for its users. You would find a lot of things about this amplifier that would keep you engaged for longer. It does have an impressive master volume and EQ settings. However, there are few other things too that would catch anyone’s attention.

To start with, you won’t be able to ignore the overdrive circuit. Here is what you can expect from Rumble 40. Unlike guitar amps that have separate clean and overdrive channels, the Rumble 40 won’t provide much of a separate channel. It gets you a circuit, which either you engage or disengage.

Or, you can also make use of a button that is located on the amp’s control panel. The footswitch is another option. However, this is not included with the standard product. You must buy it separately for around $15.

Once you would use the switch, you would know its strength for real. The overdrive is decent. But if you are expecting a proper bass fuzz pedal, you may feel disappointed. Rumble 40 is for those wanting to explore the overdriven bass sound as starters. But that does not mean you do not have more options that could get you even further with your playing experience.

Rumble 40 gets you three different bass settings. Vintage could take you through serious sound results and has been quoted favorite by many musicians who have ever tried this amp. The other two settings are the bright setting and the contour set. While the bright setting is for enhancing the high end of the tone. The latter works for the mids. The Vintage is what would carry your playing to the next level. The settings claim to outdo a tube. This does carry some extra weight though for quality sounding.


Although experienced guitarists won’t mind keeping it aside when choosing the other options, which does not mean, it is really bad. It depends on what you would like to do with this amp. It is not at all a bad amp.

For experienced players who already have an expectation set for hearing the specific sound may find it lacking some taste. But those who are still in the journey to find what they like, would definitely like this bass amp. Rumble 40 could help newcomers understand what they are looking for. It happens a lot of times when we feel creating a sound that’s stuck in our head and it does not make sense until we try it. Using Rumble 40, you can experiment with music and sound and elaborate your experience to further the vision for choosing what is right.

The Controls

There are a few controls that help you manage the sound and tone exactly as you would like it. It is not a surprise that you would find the gain control present with Rumble 40. If you have tried a few similar products, you would know that bass amplifiers usually allow users to manage the amount of overdrive in the preamp stage. This is to ensure that musicians find the ideal gain with ease. Hence, being able to create an expected overdriven sound.

Then come the damping controls and resonance. This is required to fine-tune the output that comes from your amplifier and reaches the speakers. You can find the right settings to get the sharper sound. Or, we may refer it to a more of an intensive sound catching attention when generated through the speakers.

You do have the direct output as well. This is available on the back of the Rumble 40. This could be highly useful when using the recording gear or mixes connected to the bass amplifier for the desired sound.

Apart from the ugly knobs that sit on the top, you would find this design more like a classically styled. The Rumble 40 comes with chrome corner plates. These plates go along with the silver logo of Fender and catch the sight sitting in the front.

Inclusion of Different Jacks

Now that you are getting a headphone jack to get the music right into your ears, you do not even have to worry when practicing in your studio apartment instead of the basement. Your neighbors won’t complain even if you keep playing the entire night.
