Can You Use A Guitar Amp As A Speaker – Guide 2023

Using an old guitar amp as a speaker occasionally comes up, but is it possible? Do they include the right ingredients to create this piece? An amp speaker differs from your regular speakers, so let’s find out.

A guitar amplifier is just a speaker with a circuit to control the power of a speaker. This blog will examine the different speaker cabinet brands, their pros and cons, and how to connect them to your guitar amp.

Amplifiers have been in use for a long time, and from the start, the aim has been to provide the best possible sound quality to the listener. This blog discusses how you can use a guitar amp as a speaker to get the best proper experience.

Can You Use A Guitar Amp As A Speaker?

Yes, it is possible to use a guitar amp as a speaker for playing music or other audio.

A guitar amp is designed to amplify the sound of a guitar, but it can also be used to strengthen other audio sources such as a computer, phone, or music player. To use a guitar amp as a speaker, you must connect the audio source to the amp using an appropriate cable, such as a 3.5mm audio cable or an RCA cable.

However, there are a few things to keep in mind:

  • Not all guitar amps are suitable for use as speakers. Some guitar amps are specifically designed for guitar use only and may not have the appropriate input or output connections for connecting other audio devices.
  • The tone and EQ of the guitar amp may not be suitable for playing music or other audio, as it may add unwanted distortion, hum or noise.
  • Some guitar amps are designed for high volume, which may not be suitable for indoor or small rooms; you may want to consider an alternative speaker for general use.

In summary, it is possible to use a guitar amp as a speaker, but it may not be the best option for all situations, and you may want to consider the above factors before using it.

You can use a guitar amp as a speaker by connecting a smart device, such as a phone, tablet, or laptop, to your amplifier through a 3.5mm jack auxiliary (AUX) connection.

Connecting an Amp and Smart Device:

  1. To turn your guitar amplifier off, switch it off at the socket. Then, switch it off on the amp itself.
  2. Locate the AUX input on your guitar amplifier.
  3. Plug an AUX cable into your amplifier and connect it to your device using the 3.5mm jack. This will allow you to play audio from your device through your amplifier.
  4. Double-check that all volume and distortion settings on your amp are turned completely off before beginning your soundcheck. This will help prevent unwanted feedback or distortions that could ruin your performance.
  5. Turn the amp on and slowly turn up the volume.
  6. It’s essential to avoid turning the volume up too high on your speaker, as this can cause the speaker to blow.


Choosing a suitable amplifier is essential to avoid a muddy tone when playing the guitar. Amplifiers designed to amplify mid-range frequencies often produce poorer audio quality when playing songs with high treble or bass. For the best sound quality, look for an amplifier that specifically caters to your playing frequencies.

To improve the quality of your audio when using an amplifier, you can adjust the EQ settings to compensate. However, you should avoid turning the bass up too high (more than halfway) as this can damage the amp and will likely make little difference in improving the audio quality.

It would help to avoid turning the volume up too high, as this can damage the speaker and reduce the audio quality.

The best way to get excellent audio quality from your guitar amp is to use a pedal effects board as an intermediary connection. This will give you more control over the bass, mids, and treble frequencies, improving sound.

Follow the steps as directed and turn off all devices before connecting them. Begin by clicking your pedal board to your smart device via an AUX connection, then click your effects board to your amp using a standard 1/4-inch link. Afterwards, please turn on the amp and start with a low volume before gradually increasing it, but no more than halfway. By doing this, you’ll avoid any potential damage to your equipment.

Utilizing the Amp as a Speaker for a Microphone:

When using a guitar amp as a speaker for a microphone, the quality is usually lower than when using it for music. However, you can get decent results if you follow these steps.

  • Turn the amplifier and microphone off.
  • Set your amp’s volume and distortion settings to zero before you start playing.
  • Depending on your equipment, you will need a 1/4-inch connection or an AUX lead to connect your microphone to your amplifier.
  • Make sure the amp and microphone are turned on.
  • Gradually increase the volume and check the audio quality.
  • Never turn the volume up more than halfway to avoid damaging the speaker.


Guitar amplifiers are created to amplify the centre-range commonnesses created by a guitar. The human voice, however, favours high-range (treble) frequencies, which an amplifier struggles with. Elevated-range commonnesses allow the sound to sound crispy and sharp. As a result, the style is usually muddy and muted when using a microphone through an amp.

If you’re finding that your electric guitar’s tone isn’t as sharp as you’d like, one way to change that is by adjusting the EQ on your amplifier. Try turning the bass and mids down and increasing the treble slightly (no more than halfway) to help add definition to the tone.

I recently encountered an issue with my guitar amp while using it for karaoke – there was an excessively high level of feedback. I reduced the input by making a few adjustments and wanted to share what I did in case anyone else experiences the same issue.

Avoid Using Adapters:

Adapters can create issues when people try to use a guitar amplifier as a speaker. The two main problems are:

  1. They can increase the risk of the speaker blowing
  2. It increases the number of connection points, reducing audio quality and increasing feedback. It can also lead to issues such as cross-talk and ground loops.

If you’re using an iPhone, you will need a 3.5mm adapter lighting to use an AUX connection. This is usually not an issue.

However, adapters like 1/4 inch (guitar jacks) to 3.5mm are not recommended, as guitar jacks are only designed to be used with a guitar. This could potentially damage the amplifier permanently.

Will it Blow the Amplifier?

You’re unlikely to blow your guitar amplifier by using it as a speaker unless you’re playing high volumes of bass-heavy music. When using an amp to play music or for vocals, start at a deficient volume and gradually increase it. Avoid pushing the book past halfway on the amp.

As I mentioned, you can use your guitar amplifier as a speaker at parties without issues. However, it would help if you were always cautious when using it this way. While it’s unlikely to damage the speaker when used responsibly, it’s still possible. So always avoid overloading the amp for long periods or using high volumes. Remember that this isn’t what the amp is designed for.


You can use a guitar amp as a speaker, but you have to be cautious about the amperage of the amp. Using an amp to power a speaker will damage the speaker. The speaker could be damaged because of the voltage, the current, or a combination of the two. The best option is to use a separate amp to power a speaker.

Can I use my guitar amp as a regular speaker for playing music?

Yes, you can use a guitar amp as a speaker for playing music, but there are some important considerations to keep in mind.

Will using a guitar amp as a speaker damage it?

It’s possible to damage your guitar amp if you push it too hard with loud music for extended periods. Guitar amps are designed for instruments, and prolonged use with a full-range audio signal may harm the speakers or other components.

How can I safely use a guitar amp as a speaker for music playback?

To safely use a guitar amp as a speaker, keep the volume at a reasonable level. Avoid excessive bass, treble, or gain settings, as they strain the speakers. Additionally, please don’t use it as a replacement for a dedicated, full-range speaker system.

Can I directly connect my phone or audio device to a guitar amp?

Most guitar amps lack auxiliary inputs for phones or audio devices. You might need an adapter, such as a 1/4-inch to 3.5mm converter, or use the amp’s effects loop if available.

Are there any specific types of guitar amps better suited for music playback?

If you plan to use your guitar amp primarily as a speaker for music, consider amps with cleaner tones and good speaker quality. Some modelling amps or acoustic guitar amps can work well for this purpose.
