While acoustic guitars are typically played through dedicated acoustic amplifiers or PA systems, there may be instances where you want to plug your acoustic guitar into an electric guitar amplifier for added versatility and tonal experimentation. However, it’s essential to understand the differences between acoustic and electric amplification to ensure optimal sound quality and avoid potential damage. In this article, we will provide a step-by-step guide on how to plug an acoustic guitar into an electric guitar amplifier, highlighting the necessary considerations and potential benefits.
Step 1: Choose the Right Amplifier: Before plugging your acoustic guitar into an electric guitar amplifier, it’s crucial to select an appropriate amplifier. Electric guitar amplifiers are designed to enhance and shape the sound of electric guitars, often with features like distortion, overdrive, and equalization tailored for electric guitar frequencies. Look for an amplifier with a clean, neutral channel or an acoustic-specific mode that can accommodate the natural tonal characteristics of your acoustic guitar without altering its sound excessively.
Step 2: Preparing the Connections: To connect your acoustic guitar to the electric guitar amplifier, you will need an instrument cable with a 1/4-inch TS (tip-sleeve) jack on both ends. Start by ensuring the amplifier is turned off and the volume controls are set to minimum.
Step 3: Connecting the Guitar: Locate the output jack on your acoustic guitar, typically located on the lower bout or the side of the instrument. Insert one end of the instrument cable into the output jack firmly, ensuring a secure connection. It’s important to note that some acoustic guitars may have a dedicated “preamp out” or “line out” jack, which is preferable for connecting to an electric guitar amplifier. This output provides a balanced, line-level signal and may offer better results.
Step 4: Connecting to the Amplifier: Find the input jack on the electric guitar amplifier. It is usually located on the front panel, labeled as “input” or “instrument.” Insert the other end of the instrument cable into the amplifier’s input jack. Make sure the connection is secure but avoid overtightening to prevent any damage to the input jack.
Step 5: Adjusting the Amplifier Settings: Before turning on the amplifier, ensure all volume and tone controls on the amplifier are set to their minimum levels. This precautionary step prevents any sudden loud sound or potential damage to your acoustic guitar or amplifier when you power them on.
Step 6: Powering On and Testing: Now, turn on the amplifier and gradually increase the volume levels to your desired listening level. Take note of the amplifier’s EQ settings and make any necessary adjustments to achieve a balanced and pleasing tone. Experiment with the amplifier’s controls, such as reverb or effects, to further shape the sound to your preference. It’s important to listen carefully and make sure the amplified sound reproduces the natural characteristics of your acoustic guitar accurately.
Step 7: Feedback Prevention: Acoustic guitars are prone to feedback when amplified at high volumes. To minimize feedback issues, try the following techniques:
- Stand farther away from the amplifier.
- Avoid pointing the guitar directly towards the amplifier’s speaker.
- Use a feedback suppressor or a soundhole cover designed to reduce feedback.
While plugging an acoustic guitar into an electric guitar amplifier may not provide the same tonal qualities as a dedicated acoustic amplifier or PA system, it can offer added versatility and creative options for acoustic guitarists. By following the steps outlined in this guide and considering the specific characteristics of your acoustic guitar and electric guitar amplifier, you can enjoy the amplified sound of your acoustic guitar through an electric guitar amplifier while preserving the natural qualities of your instrument. Remember to exercise caution, set appropriate volume levels, and adjust the amplifier’s EQ settings to achieve the desired tone and avoid any potential damage to your gear.
