Fender Rumble Bass Amplifier 

The Fender 15 v3 is a well-designed construction with excellent features.

Although its speaker cabinet is slightly larger than previous versions, it is surprisingly lighter with a compact spare design.

The wide cabinet offers greater capabilities in moving the sound in and out, thus keeping the sound more accurate.

But this does not indicate that the machine will be on the bulky side.

In fact, it is among music devices with the most lightweight components thanks to the optimization in construction.

Moreover, the sound quality is pretty satisfying with a clear, deep final result. If you are taking the 4-string bass practice, you would have no difficulties with the low end.

The device also adds a vintage, oldskool vibe into the design, which is a plus for art lovers.  However, you might want to put some limits on the bass frequencies when it comes to practicing at the 5-string.

The Fender Rumble Bass Amplifier is ideal for a newbie to start basic practice and want to go further in this music industry.

The internal compressor is well built, which allows the bass player to max out their tone and performance on the stage.

Fishman Acoustic Combo Amp

Most acoustic amps are famous for their portability, enabling you to carry them from place to place without too much effort.

And the Fishman Acoustic Combo Amp belongs to that group.

With a rechargeable battery, compact construction, and lightweight, the Fishman just fit perfectly into any critical standards for a portable amp.

As a result, you can hold it in one hand to move around.

However, acoustic amps usually do not perform pretty well in terms of volume. But it is not the case when it comes to the Fishman.

The Fishman volume is astounding with a combo of a 60-watt combo amp, 6.5-inch woofer, and a tweeter.

However, the device can attract dust, so that you probably want to keep it in the cleanest spot in your home.

If you want a portable bass amp for a campfire or a drive-in trip to enjoy the tunes, you would really like this one.

The device also fits for street performances.

The only thing that the device hasn't gone the way through is the range of effects.

It might not reach the most critical player's expectations.

Things To Consider When Buying A Bass Amp

Combo Amp Or Singular Head And Cabinet 

The combo amp and singular head cabinet set to bear a lot of resemblances to each other. The head consists of a preamp, a signal processor, and the main amp.

When it comes to the combo amp, it would have two distinctive pieces included in the common box.

As the combos' equipment is slightly simpler than those of the separate set, they cost a bit cheaper than when you purchase it separately.

The combos are also much more convenient to move around from place to place. You may have to expect the lack of a few inputs and outputs.

Nevertheless, the results remain the same.

Speaker Cabinet 

For the bass frequencies to be delivered smoothly without a crack, the speaker cabinet capacity should be large and have enough space for the sound to move in and out in harmony.

A standard guitar speaker cannot do that. It has limits in the construction that made it impossible to deliver bass signals in such a huge amount of movement.

For that reason, you always see the bass cabinet being carefully sealed or ported. When the bass reaches its lowest frequencies, the speaker must hold some air inside the box.

The air then can be pushed back to produce a high-quality bass tone and keep the box under control. The port tube size and length enables the speaker to keep itself stable and powerful.

Speaker Size 

Most people assume that bigger is better in terms of the bass volume, but it is not the case.

While some people would rather have a combination of small speakers in one cabinet, others prefer to have one or two significant speakers in the box.

The results for these two types of speakers are not the same.

The one with small speakers combined usually produces lighter and tighter sound, whereas one with a significantly larger one can be a little mushy.

Number Of Speakers

The speaker cabinets come with all shapes and sizes on the market.

However, the most common product usually narrows down to a specific size at 1 x 18″, 1 x 15″, 4 x 10″, and the 8 x 10".

For larger performance stages, the bass can be a combination between 1 x 15″ and  4 x 10″. Sometimes you can use a crossover to transfer lower frequencies to the 15" for optimal results.

When connected to the 4 x 10", the final sound quality would be pretty clear and punchy.

Amplifier Power 

A 100-watt amp is considered as standard equipment for decent practice.

But if your practice demands more of the low frequencies, you might need an amp with a volume from 200 to 400-watt power range because it costs a lot of power for moving the robust speaker backward and forward.

Number Of Channels 

With two channels available, you can create EQ and effect settings according to your preferences and needs.

Additionally, you are free to use both two features any time you want.

If you want to turn on the internal overdrive mode, having these two EQ and effect chain features could be a real strength to take control of the whole game.

EQ comes with various forms. It can be in the 3-knob form, or delicate parameter design, or maybe in graphic display.

The bass amps are usually heavier than a standard guitar amp.

So you should go for products with wheels or sturdy handles if you want to move it from shows to shows.

Make a wiser choice once, then be granted with great convenience forever!


As the bass volume and tone are quite large, it is critical for the bass cabinet to have a solid, sturdy design to prevent any potential damages.

The construction is usually sturdy with thick wood material. That explains why the bass amp is always heavier than a regular amp.

For further protection, the manufacturers also add metal or steel in the production process to build a complete, robust model.


The last factor but has never been out of the top concern is price.

Although we know that a dirt cheap one bass amp is no kidding a real temptation, it is best for you to buy one with the best value for money.

It will go through intensive rehearsal and explosive performance.


Can You Use A Regular Amp For Bass?

Yes, it is possible to use it in that way. However, a regular guitar amp bass is never optimized for handling bass input.

For that reason, it can lead to damage to the guitar amp when you turn on the bass mode at high volume. So take this into careful consideration before deciding to use your amp in this way.

Do I Need A Bass Amp?

If you wish to go further and dig deeper into learning bass lessons or have a greater sense in bass tone, you should go for a decent bass amp rather than the guitar amp.

Even a cheap bass amp can produce greater results than a luxurious guitar amp.

How Can I Practice Bass Without An Amp?

Practicing bass without an amp can be a real challenge, but it is not impossible.

You can still practice by using a headphone amplifier or utilizing software on your laptop.

Multi-effect processor is also another ideal option. Just decide which way is the most suitable for you.

What Does Gain Do On A Bass Amp?

The gain settings would determine the level of intensity you are going for in the preamp section.

Creating a fixed gain control will limit distortion in the tone no matter how loud you are playing for the final results.


The best mini bass amp list has laid out for you some most potential candidates on the market.

You have the best battery powered bass amp, or the best portable bass amp suggested on the list above.
