Read further for more information about low watt tube amps, as well as reviews of the best options on the market.

What is a Tube Amp?

A tube amplifier is an electric amplifier that uses vacuum tubes to increase the power of the signal. You call these vacuum tubes valves, and they are made from glass. Before you can use a tube amplifier, you must allow the glass tubes to warm for about 10 to 20 minutes. Only then can you plug your musical instrument into it and play it through the amplifier. 

All amplifiers were built like this before solid-state electronics came into use in the early 1970s. A vacuum tube is a voltage amplifier, and a transistor that is now used in electronics is the current amplifier.

How Does a Tube Amp Work?

Instead of using transistors, the tube amplifier uses vacuum tubes, or valves, to amplify the signal. Inside the tube, some electronic phenomenon takes place through heating of the plate that causes the electrons to be set loose. 

The anode is then charged with a positive voltage, and electrons can then flow from the cathode to the anode. What is basically happening is these actions inside the vacuum tube cause the signal to be amplified to give you your louder sound. 

The tube is then, in other words, the amplification device inside your amplifier to give you an output sound that easily exceeds what was put in.

What Makes a Great Low Watt Tube Amp?

What makes a great low watt tube amp is the final sound that comes out of it, and this may need some explanation. 

Sound and Volume

Whenever you play your instrument through the amplifier, what you get out on the other side of the output is a louder sound than what your instrument put in at the input side.

At a certain stage, when your amplifier is at its maximum volume, the output starts getting to be too much for your amplifying device to handle and the sound coming out at the output side becomes distorted. 

Now, because of the imperfection of the vacuum tube, the distorted sound coming out of the amplifier sounds musically better for certain styles of music like metal, blues and R&B. 

Nice Sound

While the solid-state amplification just makes the sound ugly when it comes out of the amplifier, the good thing about a tube amplifier is that when you max your amplifier the sound coming out sounds nicely distorted. 

Volume Distortion Output

With a low watt tube amplifier, your maximum volume is not too loud and that means the distortion comes earlier than with a higher watt tube amplifier. This makes it a good volume distortion output without being too loud and therefore disturbing the surrounding neighborhood. So the low, volumes maximum out distortion is the main feature for making a great low watt tube amp.

Advantages and Disadvantages of Low Watt Tube Amps

All products have both pros and cons to them. Let’s take a look at some of the upsides and downsides of purchasing and using a low watt tube amp.



Low watt tube amplifiers are great for practicing and recording. The lower wattage tube amps can achieve excellent overdrive and much better distortion at lower volumes. 


The main consideration of using a tube amp is to reproduce the rich tones of classic music styles, and the distortion of the sound comes easier and much richer than with digital electronic amps. 

Control of Tone

Tube amps clean up pleasantly and also give guitar players much more control over the overall tone. Low watt tube amps are all about recreating the timeless sounds of the original music it stems from.



Tube amplifiers need to warm up before you can use them. When you overdrive the tube amplifier, the vacuum tube will heat up and may blow, and to get a replacement may prove to be quite a hassle. 

Parts Shortages

Not all tube amp manufacturers use the same specifications when manufacturing their amplifier, and this may leave you with a shortage of available parts and vacuum tubes. Tube amplifiers are also substantially more expensive than their solid-state counterparts. 


Tube amplifiers are not as durable as solid-state amplifiers because of their complicated amplification method. Tube amps are, because of the nature of there amplification devices, much heavier than solid-state amps.


Reproducing the sounds of classical blues and rock at home and for small gigs is what low watt tube amps are all about. Considering the price and unavailability of the vacuum tubes, you might consider not buying a tube amp. 

However, if listening to your all-time favorite classic blues or rock music, the nostalgia will convince you to invest in one of the aforementioned low watt tube amps, even if it is only to play at home.
