Of course, the frequency ranges are not set in stone and you should always use your ears and taste to find the best EQ settings for your guitar sound. However, here are some tips and suggestions to help you apply EQ techniques for different genres and styles of rock music. For metal or hard rock, you may want to boost the low-end and high-end ranges for a powerful sound, while cutting some midrange to avoid muddiness. Additionally, use a parametric EQ to notch out some narrow bands of frequencies that cause feedback or resonance problems. For blues or classic rock, you may want to boost the midrange range for a warm tone, while cutting some low-end and high-end ranges to avoid boominess and harshness. A graphic EQ can also be used to shape your tone with gentle curves and slopes. For pop or indie rock, you may want to cut the low-end and midrange ranges for a clear tone, while boosting some high-end range to add sparkle and airiness. A parametric EQ can be used to fine-tune your tone with subtle adjustments, as well as high-pass and low-pass filters to remove any unwanted frequencies. With an understanding of types of EQs, common frequency ranges, and tips for different genres and styles, you can improve your EQ skills and craft your own signature sound.
