Acoustic Guitar Amp Buyers Guide
Amps are an integral part of a guitarist’s playing routine and choosing the best for you requires some thorough researching. As for the question about needing an amp for your acoustic, it really comes down to your own playing style. A lot of people wonder "why bother?" with an amp when playing an acoustic guitar since these instruments are all about the natural sound. Some acoustic guitars require a bit of a volume boost and this is where the acoustic guitar amp works its magic.
Types of Amplifiers
Essentially, there have historically been two types of amps but there is a third new kind as well.
Solid State Amp
A solid state amp utilizes transistors for its preamp and power sections. It has a cleaner sound and is usually considered the most reliable type of amp. They aren't exactly digital amps, however, they do utilize new technology, transistors in this case, for amplification. The quality has improved in a bit way since they first came on the guitar scene.
The tube amp produces warmer and more organic sound. These involve tubes which amplify the sound signal and need to be replaced from time to time. If you want a warm sound with a vintage vibe then tube amps are your best bet. This is the oldest kind of amp and guitarists have been using them for decades. They tend to be expensive.
Modeling amps are the newest type of amp and are also known as digital amps. These use processors to amplify guitar tones. They aren't entirely digital; they still need a solid state preamp. With quality processors and advanced software, modeling amps have the potential to become the go-to amp of the future. However, many guitarists prefer the other two amps and only use digitals amps for practicing. Regardless of its popularity, the big advantage of modeling amps is that they have so many effects. That said, it's easy to distinguish the sound of a modeling amp from that of a solid state or tube amp.
For beginners, solid state is probably the best as it is the most reliable type of amp. However, it really is up to your own taste as to what type of amp produces the sound you're looking for.
Features of Acoustic Guitar Amp
This is often found on amps designed for acoustic guitars as the signal on these guitars comes either from a microphone or transducer pickup. Because of this, there is room for feedback which needs to be reduced with some kind of feedback control.
This is the feature you should be most concerned about. The line or microphone input feature could possibly have XLR input and a phantom power option. Having an XLR input can be a great thing; it's basically a PA system in its own right, so you don't need to hook up a PA system when playing on stage. If you think this is something you could benefit from, look for this feature.
Now there are many effects that come built-in with acoustic guitar amps, but you need to identify which effects you need. It might be better for you to have these effects right in the amp rather than getting standalone pedals. Effects include things like compressor and loop. The latter can be great for solo guitarists to create different rhythms and play solos over them. For the acoustic guitar sound, the reverb is probably the most important effect you'll want to consider. Reverb basically creates a robust sound that can brighten your acoustic guitar playing. Again, all of this comes down to your own playing style and the kind of sound you're after.
Power depends on your surroundings and audience. If you're just planning on practicing at home, 20 to 30 watts of power is more than enough. The power of your amp should increase as the size of your playing venue increases. If you're playing a coffee house, you'll need at least 50 watts. Bigger venues may require you to have as high as 100 watts, especially if you're playing with other musicians. The more the power in the amp, the louder the sound will be, so figure out where you'll most likely be playing and choose accordingly.
You also have stereo amps as an option. Decide how you want to use your amp and the effects you'll be using most often. For instance, a mono wouldn't work best for ping-pong delay. However, if you just want the pure, simple and warm acoustic sound, you can go for the mono option.
A combo can be very useful for those looking for an all-in-one option. Combo boxes come with amps and speakers integrated into one. The obvious benefit is that you have everything you need in one place. However, the quality of a combo can vary. Some sounds may be great but others might be lacking. The real question is how much power you need to pack into these things. Remember there are only so many speakers you can fit into a box. Even though a combo is a standalone unit, some come with outlets for adding secondary speakers to increase power. So long as it retains the quality of your acoustic guitar, you can have as much power as you like.
Quality should be an important factor when buying an amp. It can have a real impact on the amp’s performance. The difficult thing is that quality isn't easily defined. One thing to look for is design and materials. If the materials are high-quality then the amp is likely to be high-quality as well, and produce top-level sound. To figure this out, you'll have to get into the details of the different amps you're considering. To take your sound to the next level, have a look at some of the top guitar cables money can buy.
Go for an amp that can stand the wear and tear of frequent, heavy use. If it can, you know you've got some great quality gear on your hands. As a general principle, expensive products from well-known brands are generally better quality compared with cheap options.
Prices vary depending on brands and the features the amps have. Usually, solid state amps are the cheapest, but even their price ranges can vary greatly. Expect to pay at least $100 for a quality amp for your acoustic guitar. If you go further up the scale, you can find some truly outstanding tube-based amps from the more high-end brands. These can set you back as much as $500 or more.
Unless your budget is really low, finding a decent quality amp with a number of effects shouldn't be too difficult. The combo options are an economical solution as they have speakers included as well.
Another important factor is to identify your own needs and playing style. If you're planning on buying something that doesn't jive with your playing style but is in your budget range, there isn't much of a point in buying it. Only buy amps that are suitable for your style and the types of venues you play.
Embedded Effects - Having built-in effects can be extremely useful for live performance. However, if your amp of choice doesn't have this option, don't sweat it: You can always supplement with guitar pedals in the future if need be.
What is an Acoustic Guitar Amp?
A guitar amplifier is an electronic amplifier which picks up a weak signal from the bass, electric, or acoustic guitar and strengthens it. The output signals are produced by external speakers or loudspeakers housed in a wooden cabinet in the amplifier.
Types of Guitar Amplifiers
A standalone is a guitar amplifier which only contains a power amplifier or preamp for boosting the signals. One needs to connect an external loudspeaker to hear the output.
A combo is an amplifier which contains both speakers and a power amplifier packed into one metal or wooden cabinet.
Combo guitar products can include a single 8" speaker for casual use or up to four 10’’ speakers for nightclubs or heavy usage.
Apart from boosting the weak guitar signals, a guitar amp is capable of doing much more. Guitar amplifiers can also modify the tone of the instrument. They're equipped with controls to emphasize or deemphasize frequencies, add electronic effects, manage distortion, and edit reverb same just like the bass and treble knobs on your home hi-fi system.
The electric guitar uses an electromagnetic pickup to pick up signals while an acoustic guitar uses a piezoelectric pickup. The signals are then transferred via a patch wire that plugs into a ¼’’ jack of the amp.
As its name suggests, an acoustic guitar amp is intended for amplifying the signals of an acoustic guitar. They are mostly used in folk and bluegrass. Acoustic guitar amps and keyboard amps share many similarities with one another. They have a flat frequency response and are specially designed so that power amplifier and speakers don't conflict with each other.
Acoustic amps are known for providing clean sound, additional headroom, and less distortion. All this is achieved by powerful products (rated up to 800 watts RMS). Most of these use Class AB circuits for providing heavy sound while some used Class D circuits to cut off that heavy sound. They're also called switching amplifiers.The amp box also includes a simple mixer control to blend signals from instruments and microphone into one. Most of them offer a range of digital effects like reverb, compression etc.
On the whole, an acoustic guitar amp includes some digital effects to pre-edit and boost the signals of an acoustic guitar.
How Important is an Acoustic Guitar Amp?
Acoustic guitars produce sound from their hollow bodies. The output is decent if you're practicing alone but you'll get drowned out trying to rock the stage with a standalone acoustic guitar.
Acoustic guitars are meant for quiet, solo performances as they don't produce a gigantic sound. If you want a crowd to hear your acoustic guitar skills you'll definitely need an acoustic guitar amp.
What purpose does an acoustic guitar amp serve? Basically, an acoustic guitar amp boosts the acoustic guitar's signals (sensed by a built-in piezoelectric pickup) so that they can be outputted by a loudspeaker.
When you connect your acoustic guitar to the amp, the signals from your guitar are routed by a patch record wire (in some cases wirelessly) to the acoustic guitar amp. In the box, the weak signals are boosted to strong signals. They are then routed to external speakers or built-in speakers to produce the output.
If you're looking for a more studio sound, take a look at the recommended studio monitors or a home set up right here.
If you are among those who prefer to play solo don't worry about buying an acoustic guitar amplifier. On the other hand, if you're an acoustic guitar pro with upcoming stage shows then you should consider adding an acoustic guitar amplifier to your gear.
How do You Set up an Acoustic Guitar Amp?
Although acoustic guitar amplifiers use a plug-and-play mechanism, we’ll guide you on how to properly set up your first amplifier.
- Most have detachable power cables. First, plug the female side of the cable into the amp, then plug in the male side to the power outlet.
- The majority are loaded with speakers (known as combos). If you have a standalone amp, set up a cabinet for speakers and amp. Now connect your speakers to the amplifier.
- Now it's time to connect. Run an audio cable from your guitar’s output jack to the amplifier’s input jack. (Note: always plug the cable into the amplifier while it’s turned off.) Some have more than one input jack, connect the audio cable to both inputs one by one to check the best output.
- Turn on the amplifer's power button.
- After turning on the amplifier, it’s time to set the volume. You’ll usually find two volume controls, Drive and Master or Pre and Post. The first control adjusts the signal before it has been amplified, while the second one adjusts the signal after it has been amplified. We’ll concentrate on the second one “Master” or “Post”. Turn up the volume to the desired level.
- If you want a distorted effect you can adjust the “Drive” or “Pre” control.
- Now adjust the EQ of your guitar’s tone. On every amp, you’ll find the bass, treble, and mid controls. For outputting a natural tone, set all knobs to a twelve-o'clock position (directly in the middle). Similarly, if you want to produce higher frequencies set the controls to high and vice versa.
- If your product includes a channel button, use it to switch between clean and distortion channels.
- Now set the gain level. The gain knob is featured to increase distortion and volume. Not all amplifiers are loaded with gain control. Mostly rock and blues musicians prefer increasing gain.
- Additional controls like reverb, delay, chorus exist to get even more out of your instrument. The most common feature available in all amps is reverb. Reverb stimulates different sounding effects like hall, room, auditorium, etc.
Setting up an amplifier is easy!
When to Consider an Acoustic Guitar Amp?
An acoustic guitar amp is mostly needed by folks who perform in front of a crowd. For an instance, if you've trained yourself on an acoustic guitar and want to perform on stage at a gig, the best thing to do would be to buy an acoustic guitar amp to boost your acoustic sound rather than trying to swap to an electric guitar.
A solo musician who records or play his instruments at home, you won’t find an acoustic guitar amp appealing.
Can I use an Electric Amp for an Acoustic Guitar?
Saving cash huh? Well, it’s perfectly alright! It’s a good idea to pair your acoustic guitar with an electric amp if you have one laying around. It won’t damage your guitar or amp.
Mostly, people who can’t afford to buy an additional acoustic guitar amp use their electric amps as an alternative. An electric amplifier picks up the signals from an acoustic guitar.
So why make separate amps? Basically, an acoustic guitar is known for outputting a cleaner sound whereas an electric guitar produces a distorted sound. Similarly, an electric amplifier is crafted to boost the distorted signals while the acoustic amplifier is designed to boost the clean signals.
You can use an electric amp for an acoustic guitar if you know how to properly adjust the controls for the desired output.

Some Guitar Amp Myths
“Bigger is Better.”Bigger is not always better. Check your playing venue. Most guitarists don't need more than 50 watts.
“Brand Name.” Even popular brands make useless products. They can also make some awful mistakes resulting in an inferior product. Don’t get carried away by a cheap branded amp that promises a lot.
“Comparing pedal with built-in effects.”Built-in effects are good but they can’t match the superior quality of separate pedals. They are specially made to only output effects. Any company which states built-in effects are superior to pedals is simply trying to sell you their product.
