Electric guitar amps can sometimes sound harsh when they’re miked up. Here are some tips for controlling the high end when miking an amp:
- Try different mic positions – centered on the speaker, near the edge, in the middle. Different frequencies may be emphasized by different areas on the speaker cone.
- Angle the mic – turning the mic slightly off-axis will change its frequency response and change the sound.
- Pull back – a bit of distance can allow the sound of the amp/speaker to “develop” a bit. After all, we never listen to an amp with our ear pressed tight to the cone (thank heavens!).
- Fix it at the source – don’t forget to try different guitars, different amps, different speakers, different amp settings, etc. Get it sounding right acoustically, then place the mic in a way to best capture that sound.
