Using a Shure SM57 to mic your guitar amplifier is a popular choice among musicians and sound engineers. Its durability and clear sound make it an ideal microphone for capturing the tone of your guitar amp. This quick guide will walk you through the essential steps to set up your SM57 effectively.

Preparation Before Miking

Ensure your guitar amp is set to a desired volume level. Position the amp in a suitable space with minimal background noise. Gather your SM57 microphone, a microphone cable, and a microphone stand. If available, have a mixer or audio interface ready for connecting the microphone.

Positioning the Microphone

Place the SM57 close to the speaker grille of your guitar amp. For a balanced sound, position the microphone about 1-3 inches from the cone. Experiment with angles—aiming directly at the center for a brighter tone or toward the edge for a warmer sound. Use a stand to keep the microphone steady.

Optimal Placement Tips

  • Position the microphone at the center of the speaker cone for a brighter tone.
  • Move toward the edge of the cone for a warmer, mellow sound.
  • Adjust the distance to control the amount of direct sound and room ambiance.
  • Try angling the microphone slightly to reduce unwanted reflections.

Connecting and Testing

Connect the SM57 to your audio interface or mixer using a quality XLR cable. Turn on your amplifier and set it to a moderate volume. Gradually increase the gain on your audio interface or mixer while tapping the microphone to check for signal.

Final Adjustments

Listen to the sound through your monitoring system. Make small adjustments to the microphone position and gain levels to achieve the desired tone. Avoid clipping or distortion by not setting the gain too high.

Additional Tips for Best Results

  • Use a pop filter or windscreen if necessary to reduce unwanted noise.
  • Record a short test to compare different mic positions.
  • Consider using a small amount of EQ to shape the tone if needed.
  • Ensure your cables are secure and free from damage to prevent noise issues.

With these steps, your Shure SM57 will be set up to capture your guitar amp's tone effectively. Experiment with positioning and settings to find the sound that best suits your style.
