Acoustic guitars produce beautiful, natural tones, but sometimes their volume isn’t enough for live performances, busking, or recording. Amplifying an acoustic guitar allows you to project its sound more effectively without losing the warmth and richness of the instrument.
Whether you’re performing on stage, playing in a band, or simply wanting to boost your sound, this guide will help you explore the best ways to amplify your acoustic guitar.
Why Amplify an Acoustic Guitar?
Amplifying your acoustic guitar provides several benefits
- Increased Volume – Ensures your guitar is heard in live performances.
- Better Sound Projection – Ideal for playing with other instruments.
- More Control Over Tone – Adjust EQ settings for a customized sound.
- Enhance Effects – Add reverb, delay, or chorus for richer tones.
- Easier Recording – Get a clear and consistent sound for recordings.
If you want your guitar to sound great in different environments, amplifying it correctly is key.
Methods to Amplify an Acoustic Guitar
There are multiple ways to amplify an acoustic guitar, each with its own advantages and ideal use cases.
1. Using an Acoustic Guitar Amplifier
An acoustic guitar amp is designed to amplify your sound while maintaining the natural tone of your instrument.
How to Use an Acoustic Amp
- Plug your guitar into the amp using a 1/4-inch instrument cable.
- Adjust the volume and EQ settings (bass, mids, treble) to get the desired tone.
- Position the amp correctly—elevate it or angle it towards your audience for better sound dispersion.
- If feedback occurs, reduce the gain or reposition the amp.
Best Acoustic Guitar Amplifiers
- Fender Acoustasonic 40 – Great for small gigs and practice.
- Fishman Loudbox Mini – Lightweight and powerful.
- Boss Acoustic Singer Live – High-quality sound with built-in effects.
If you’re a performer or play gigs often, an acoustic amp is one of the best ways to amplify your guitar.
2. Using a PA System
For larger performances, a PA system (Public Address system) is a great option. It provides a clear, balanced, and loud sound across a venue.
How to Connect an Acoustic Guitar to a PA System
- Use a DI Box (Direct Input Box) – Converts the guitar’s signal to a balanced output for better clarity.
- Plug into a Mixer – The PA system’s mixer lets you adjust sound levels and EQ.
- Set Up Microphones if Needed – Some players prefer combining pickup signals with a microphone for a more natural sound.
This method is perfect for band performances, live shows, and professional events where powerful sound projection is needed.
3. Using a Microphone
Miking your guitar is one of the most natural ways to amplify its sound while preserving its tone.
Best Microphones for Amplifying Acoustic Guitar
- Shure SM57 – Dynamic mic, great for live performance.
- AKG C414 – High-end condenser mic for professional recording.
- Audio-Technica AT2020 – Affordable and great for home studios.
How to Properly Mic an Acoustic Guitar
- Use a Condenser Microphone – Captures detailed sound.
- Position the Mic Correctly – Place it 6-12 inches away from the soundhole and slightly angled toward the fretboard.
- Avoid Feedback – If using live, keep the mic away from monitors to prevent unwanted noise.
This method works well for recording studios and acoustic performances where a natural tone is preferred.
4. Using an Acoustic Guitar Pickup
If your acoustic guitar doesn’t have built-in electronics, you can install a pickup to amplify it.
Types of Acoustic Guitar Pickups
- Piezo Pickups – Mounted under the bridge, producing a bright sound.
- Magnetic Soundhole Pickups – Easy to install and deliver a warm tone.
- Microphone Pickups – Capture a natural sound, but may be prone to feedback.
How to Install and Use a Pickup
- Choose the pickup type that suits your playing style.
- Attach the pickup to your guitar (soundhole or bridge).
- Plug into an amplifier or PA system.
- Adjust volume and EQ settings for the best tone.
Pickups provide a more portable and convenient amplification method compared to microphones.
5. Using Effects Pedals
Adding effects pedals to your setup can improve the amplified tone of your acoustic guitar.
Best Pedals for Acoustic Guitar
- Reverb Pedal – Adds depth and ambiance.
- EQ Pedal – Helps control your tone for clarity.
- Compressor Pedal – Balances sound dynamics.
- Looper Pedal – Lets you layer sounds for solo performances.
To use pedals, connect your guitar to the pedals first, then route the signal to an amp or PA system.
Common Problems When Amplifying an Acoustic Guitar and How to Fix Them
1. Feedback Issues
Problem: Loud, high-pitched squealing when plugged in.
Solution:
- Lower gain and volume.
- Use a feedback suppressor or soundhole cover.
- Change the amp position.
2. Thin or Harsh Tone
Problem: The amplified sound lacks warmth.
Solution:
- Adjust EQ settings—reduce treble and boost mids.
- Use a microphone pickup for a more natural tone.
3. No Sound When Plugged In
Problem: Guitar doesn’t produce sound through the amp.
Solution:
- Check if the guitar’s battery (if active pickup) needs replacing.
- Ensure the cable is fully plugged in.
- Try a different cable or amplifier to rule out equipment issues.
