How to increase guitar amp wattage

For guitarists, achieving the perfect balance of tone and volume is essential to making a powerful musical statement. However, there may come a time when you find that your trusty guitar amplifier lacks the wattage needed to cut through the mix or fill a larger venue. You may wonder, “How can I increase my guitar amp’s wattage?” In this comprehensive guide, we will explore various techniques and options for boosting your amp’s wattage, allowing you to command attention and deliver your music with authority. Whether you’re a seasoned performer or just starting, this article aims to demystify the process of increasing your guitar amp’s wattage and provide you with the knowledge to make informed decisions about amplification.

To understand how to increase your guitar amp’s wattage, it’s essential to explore the underlying principles and methods involved. Join us as we delve into the various strategies and considerations for achieving higher wattage in your amplifier.

Understanding Amp Wattage:

Before delving into how to increase your guitar amp’s wattage, let’s briefly review what wattage means in the context of amplifiers:

  • Wattage is the measure of an amplifier’s power output and is directly related to the volume it can produce. Generally, higher wattage amplifiers can produce louder sound levels.
  • Wattage alone doesn’t determine tone. It influences the headroom, which is the amp’s ability to stay clean at higher volumes. A higher wattage amp typically has more headroom, allowing for cleaner tones at higher volumes.

Now, let’s explore various strategies for increasing your guitar amp’s wattage:

1. Upgrading Speaker(s):

One of the simplest ways to boost the wattage of your amplifier is by upgrading the speaker(s). The speaker’s power handling capacity significantly affects your amp’s overall wattage.

  • Solution: Choose a higher-wattage speaker that matches your amplifier’s impedance rating. Ensure the new speaker’s sensitivity rating is compatible with your amp. Professional installation is recommended for safety and optimal performance.

2. Adding an External Speaker Cabinet:

Another way to increase wattage is by adding an external speaker cabinet to your setup. This effectively combines the wattage of the amplifier and the external cabinet.

  • Solution: Connect your amplifier’s speaker output to the external cabinet’s input using the appropriate cable. Ensure that the cabinet’s impedance matches your amp’s specifications.

3. Using an Attenuator:

An attenuator is a device that sits between your amp’s output and the speaker(s) and allows you to reduce the amp’s output wattage while maintaining the desired volume level.

  • Solution: Install an attenuator in your signal chain. Adjust the attenuator to decrease the amp’s output wattage while achieving the desired volume. This can be especially useful for tube amplifiers that sound best when pushed hard.

4. Switchable Wattage Amps:

Some amplifiers come with switchable wattage options, allowing you to reduce the wattage for lower volume settings.

  • Solution: If your amp has this feature, use it to switch between different wattage settings based on your performance needs.

5. Amp Modding and Rebuilding:

For experienced amp enthusiasts, modding or rebuilding an amplifier can be an option to increase wattage. This involves modifying or replacing components to handle higher wattage levels.

  • Solution: Consult with a qualified amp technician or builder to discuss the feasibility and safety of modding or rebuilding your amplifier for increased wattage.

6. Purchasing a Higher Wattage Amp:

In some cases, the most straightforward solution might be to invest in a higher wattage amplifier that meets your performance requirements.

  • Solution: Research and select an amplifier with the desired wattage and tonal characteristics that suit your playing style and musical genre.


Increasing your guitar amp’s wattage can be a strategic move to meet the demands of various performance settings and musical genres. However, it’s essential to consider the compatibility of any upgrades or modifications with your amplifier and your specific musical goals. Always prioritize safety and consult with experienced professionals when making significant changes to your amplifier setup. Armed with the knowledge gained from this guide, you can confidently explore options to power up your sound and achieve the volume and tone you desire in your musical journey.
