If you’re an experienced musician who’s developed an interest in the blues but can’t quite get the sound right, the right amp could make all the difference. The best blues amps feature preamp and power tubes that create a vintage, complex sound that’s necessary to capture the essential qualities of the genre.
When choosing the products for this review, we looked at some of the most critical factors involved in capturing the true sound of the blues. We chose combo amps, which means they’re housed with a speaker, so you don’t need to worry about buying anything extra. We included amps with wattage as low as 15 and as high as 50, so there’s something here to play an open mic night at the local coffee shop or perform at a larger venue with an ensemble. Inputs and outputs are also important because they determine what other equipment and accessories you can use with the amp. Finally, we looked at dimensions to help you determine how portable each amp is.
We spent hours and hours researching these products by reading expert opinions, manufacturer specs, and comments and reviews from the musicians who use these amps every day. The first thing you’ll come to is a table where you can quickly see how our picks compare to one another. Next are in-depth reviews of each amp, followed by a detailed Buying Guide, so you’re as prepared as possible to find the best blues amp for you.

Our next pick is the VOX AC15C1X Guitar Combo Amplifier. Vox first released the AC15 in the late 1950s and it soon became legendary. It was used a lot until the 1960s when stacks came into fashion and interest started to fade. In 2013, Vox brought it back.
What makes this amp so special? It has two channels, one for normal play and one for a power boost. They share a master volume control and a feature called Tone Cut, which modifies tones between the amp to the speaker instead of during preamp. Each channel has independent volume control in addition to the master volume. Boost mode also has its own bass and treble controls. All of this gives you a lot of control over tone.
Other features include a built-in tremolo effect with adjustable rate and depth as well as spring reverb to create more traditional sounding notes.
This amp is portable but at just shy of 50 pounds, it’s a little cumbersome to lug around. It’s equipped with an output jack for an external speaker and can easily be used to play in smaller clubs or bars.

Things to Consider
The goal of finding the right blues amp is to enhance all the things about the blues that make the genre special. Here are some things to consider while you shop.
What makes a blues amp special?
A good blues amp is one that supports the unique qualities of the music. This genre originated in the Deep South way back in the 1870s and sprung from African American spirituals, chants, and rhymes, among other things. Blues is characterized by patterns, most notably call-and-response and repetitive rhythms and bass lines.
So, what does this have to do with an amp? Well, one of the things that all of these amps have in common is they use preamp and power tubes to create a unique sound. It has an almost vintage quality that distorts and clips while building deep layers and adding nuance. These qualities serve the genre well by delivering not only dynamic tones but also the clarity needed to follow the repetitive bass lines, rhythms, and patterns that make the blues what it is.
Features to consider while choosing a blues amp
There are a few specific things to look for when trying to find the best practice amp for blues or one suitable for a performance. Let’s take a look at these qualities in detail.
Type and Configuration
All of the amps we included in our guide are combo amps. That means that a single housing holds both the amp and the speaker. The alternative is a stack which is made up of an amp in its own housing with separate speakers.
Combo amps are very portable and lend themselves to the blues quite well. The compact size produces a sound that’s a little rawer and not as overproduced which lends itself to the nature of this type of music.
Power and speakers
The number of watts varies in these speakers, from the 15-watt VOX AC15C1X Guitar Combo Amplifier to the 50-watt Boss KTN-50 12-Inch Katana Combo Guitar Amplifier. People often think that power simply means volume but that’s not exactly true. Watts are an indication of how the amp responds at high volumes. So, a 15 and a 50-watt amp might be capable of playing the same decibel level (or volume). At a certain point, the 15-watt amp loses clarity and quality while the 50-watt amp still sounds great. So, power is more of a measure of how much volume the amp can handle rather than a measure of volume.
All of these amps have one speaker, which makes sense when considering how they’re constructed. Placing two speakers in what is essentially a pretty confined space wouldn’t benefit the sound at all. Plus, because these amps all use tubes, there isn’t much room to spare.
Inputs and outputs
Inputs and outputs expand the use of the amp. Input jacks let you add foot pedals, headphones, recorders, or other accessories that can take the amp and your sound even further.
Since these amps are designed with a bit of a vintage feel, it’s not surprising that they each feature an analog interface, simple knob controls, and easy-to-read dial settings. While you can use modern recording devices by taking advantage of the inputs and outputs, the amps themselves look pretty old school.
Weight and Dimensions
If you’re planning to take this amp with you to gigs or move it from one room of your home to another, it’s important to consider weight and dimensions. Choose something that easily fits in your space that you can lift on your own.
Warranties are always important, especially when it comes to products like these. Anything with a lot of electronic, internal pieces needs a decent warranty, especially if you’re going to put it in the back of your van and drive from one gig to another. Luckily, these amps all have pretty decent coverage. The Monoprice 611815 Guitar Combo Tube Amplifier and the Fender Blues Junior Lacquered Tweed Amplifier each have a one-year replacement warranty. Most of the others have a one-year limited warranty.
No, they’re two different things. A preamp processes signals from your guitar to the amp. The amp then processes the signal from the preamp and sends it to the speakers. Interestingly, an amp can be used as a preamp in certain setups but not the other way around.
The damping factor is a little difficult to explain. Basically, it shows you how much control the amp has over the speaker. Technically, it’s the output impedance of the amplifier divided by the input impedance of the speaker. Damping factor is a really important thing to consider if you’re purchasing an amp separate from a speaker because you need to know how the two match up. Tube amps like the ones in our list have low damping factors which is one reason that they sound so unique.
Yes, you can. In fact, changing the speaker is an easy way to upgrade the sound of a combo amp. It’s important to choose replacement speakers that are the same impedance as the ones you’re replacing to maintain the damping factor. Your new speakers should also have the same power and matching mounts if possible.
Our top pick for best blues guitar amp is the Fender Blues Deluxe Reissue Guitar Combo Amp. The vintage-style tube design provides the rich tones that Fender is known for. It features a three-band equalizer, spring reverb, and effects loop among other things. Plus, the retro styling just looks really cool.
Next, we recommend the Marshall DSL20C Guitar Combo Amplifier. This amp features an all-tube circuit, 12-inch speaker, and semi-open back. You can adjust highs, mids, and lows for two different channels as well as reverb and Tone Shift. This is a great investment for a beginner and even experienced players will love it.
Finally, we recommend the Monoprice 611815 Guitar Combo Tube Amplifier for best small tube amp for blues. The stylish design features a leather handle, faux-leather exterior, and chrome corners. It uses three preamp tubes and two power tubes and features an equalizer that adjusts highs, mids, and lows as well as an FX loop to change up your sound even more.
