Now, even though we have recommended the best small tube amps, it is still helpful to know the basics. Here are some of the most common FAQs about small tube amps:

What exactly is a small tube amp?

As mentioned earlier, there are different kinds of amps. As the name suggests, a small tube amp is an amplifier that uses small vacuum tubes to create power that amplifies the sound of a signal.

For a small tube amp, the tubes are normally small and they will generate heat as they play. They will normally need a cooling system that explains why most of them are open-backed. Most of them will have to warm up to produce the sound that you are looking for.

Can small tube amps work for all genres?

Some small tube amps can work for all genres while they are those that are limited to some genres. For example, if you want an amp for jazz, you will need one that can give you a crisp sound. From the ones we have reviewed, the California Tone Research SET5 would work best for jazz as it has clear tones and just the right wattage.

Is there a small tube amp for bass?

It is hard to get a small tube amp for a bass guitar. Small tube amps have been made in such a way that when they reach a certain level, they break. That makes them suitable for any average electric guitar. A bass guitar, however, needs more wattage, with a minimum of at least 500W. Generally, a small tube amp will have a maximum of 100W. If you use a 100W amp with a bass guitar, it will not give you the desired sound and may damage the amp.

Do small tube amps only have two tubes?

Even though most small tube amps have two tubes, some have one tube or even more. Most average ones will have one preamp tube and one power tube. More tubes simply means that they will need more watts, and will be more costly by comparison.

How small can a tube amp be?

The truth is that a small tube amp can get as low in wattage as you can imagine. You can actually get a small tube amp with only 1W. It is a small palm-sized amp, but still has many great features that you can enjoy if you are not looking for much.

Conclusion

Before looking for the best small tube amp, you first have to define your needs. Once you know what you want, it will be easier to get it. It is also important to consider the features that come with the amp. Some amps have more than others, but what matters is which ones you’ll actually use.

The kind of sound you are looking for and how you plan to use the amp should be major considerations, as not all amps work in all situations. As much as price is an important consideration, you should consider it in comparison to the set features and the wattage you’re getting. Generally, more features cost more money, but this is only beneficial if you’re going to need them.

Lastly, you can gauge the experiences of others through user reviews. Be sure to check out other user reviews of these amps before you make your final decision!
