Can a Speaker Be Used as a Guitar Amp?

So, can a speaker be used as a guitar amp? It’s common practice to utilize a guitar amplifier as an external speaker for singing or playing music; I’ve used mine at gatherings for several years. However, to be safe and achieve the finest audio quality possible, you should bear a few things in mind.

It is possible to utilize guitar amplifiers as speakers. However, the audio quality will probably be less than regular speakers, and too much volume should be avoided as it might damage the speakers.

Also, avoid playing music with many basses to get the finest quality and keep your amplifier safe. Let’s dig deeper to know how you can use a speaker as a guitar amp.

How to Use Your Guitar Amp to Play Music

Playing music via your guitar amp is the most typical application of using it as a speaker. Any guitar amp may be used to play music. However, some are simpler to operate than others.

  1. The amp and the outlet on your guitar amplifier should be turned off.
  2. Find your guitar amplifier’s AUX input.
  3. Use the 3.5mm connection on your device to attach an AUX cable to your amplifier.
  4. Ensure your amplifier’s volume and distortion controls are all set to 0.
  5. Start the amplifier, then gradually raise the volume.
  6. Do not increase the volume over halfway to prevent the speaker from blowing.

You can play music or anything else you want via your guitar amp if it has a 3.5mm (1/8′′) aux input, a feature found on many contemporary amps. Some amplifiers have a 6.3mm Aux input jack. Use the adaptor described later to play music through these inputs.

You may connect your smartphone, computer, tablet, or audio source with a 3.5mm output to an Aux input.

How to Make a Guitar Amp a Music Speaker

By attaching a smart device, such as a phone, tablet, laptop, etc., to your amplifier using a 3.5mm connector, commonly known as an Auxiliary (AUX) connection, you may utilize a guitar amplifier as a speaker.

The sound quality coming from a guitar amplifier

It’s critical to comprehend guitar amp limits before utilizing your guitar amp as a speaker. This is because a guitar amp’s frequency range is quite constrained. Therefore, you can determine what a speaker system can handle by looking at its frequency range.

A bass guitar amplifier, for instance, may create very low frequencies, but they perform poorly at higher frequencies. Although a guitar amp may play low and high frequencies, they mostly concentrate on mid-range frequencies appropriate for guitars.

This implies that music played via a guitar amp would probably sound muddy and low-quality compared to a speaker system (or headphones) with a wide frequency range.

Expect little results even if you utilize the guitar amp’s EQ to attempt to make up for the issue. Some guitar amplifiers come with a full frequency range for playing back music.

What happens if your guitar amplifier lacks an Aux input?

Although many contemporary guitar amplifiers lack Aux input jacks, others do. This can make using your guitar amp as a speaker a little more difficult, but not impossible.

You might try the following options:

Use the Instrument In jack.

In this method, you disconnect your guitar and connect your music source via the guitar input jack.

You will need a 3.5mm to 6.3mm (1/8″ to 1/4″) converter to connect a regular 3.5mm cable to the guitar input port. This adaptor style is also useful if you wish to use headphones to play electric guitar.

Since guitar input jacks weren’t intended to accept anything other than a guitar, you must use this approach with extreme caution. I accept no responsibility for the misuse of this technology, which makes it very simple to destroy a guitar amp.

If you decide to try this method, be sure your amp is set to a clean channel, and the level is extremely low when you first start playing.

Please don’t push the volume; instead, gradually increase it. Guitar amps weren’t made to handle extremely loud inputs from guitar jacks.

The drawback of this strategy is that you can’t simultaneously play guitar and music.

Use a multi-effects pedal.

Many feature an Aux input jack that lets you attach whatever audio source you choose.

This method allows your multi-effects unit to simultaneously handle both the guitar signal and the music signal while still producing high-quality results.

Depending on the multi-effects pedal, this input may be marked as a CD/MP3 input with a 3.5mm connection or an AUX Input with a 6.3mm jack. Both will function properly, and all you need to connect your audio source is the proper adaptor.

A-Line 6 HD500X is seen in the image above with a 6.3mm AUX input and a 3.5mm CD/MP3 input.

As with any other technique, start by setting your music player at a low volume and increasing it gradually rather than plugging it in unintentionally at full volume and running the risk of breaking your equipment.

Use a guitar amp with a full-range speaker.

Some guitar amps include speakers that can play music along with your Instrument that are integrated into the cabinet. For example, a standard guitar speaker is included in the Line 6 AMPLIFi (link to my review), along with four full-range speakers for music playback and some guitar effects.

Sometimes, a guitar amplifier doubles as a Bluetooth speaker and a standard guitar amplifier. You may connect to it with your smartphone or any other Bluetooth-enabled device to play music via it. Then, you may listen to music through the speaker when you play the guitar.

Using a Guitar Amp with a Microphone for Vocals

You might be curious whether you can simultaneously utilize your guitar amp as a speaker for your voice if you play the guitar and sing.

Mic on Guitar Amplifier

Acoustic guitar amplifiers can accept a microphone directly, not electric guitar amplifiers. Therefore, a multi-effect pedal or appropriate preamp is required before connecting a microphone to an electric guitar amp.

Conclusion

This primary aspect is that performing music over a standard guitar amp is feasible; you shouldn’t anticipate excellent results. Get a speaker system made to handle everything you want to put at it if you want the best results because guitar amp speakers weren’t made to handle the frequency range of regular music or other instruments.
