DI’d Acoustic Guitar
35Hz – 100Hz: Cutting in this region can help reduce rumble.
100Hz – 200Hz: This range is primarily responsible for the
boominess of your acoustic guitar. Cutting or boosting here can help
with low end projection.
400Hz – 500Hz: Boosting in this range can bring out warmth. Cutting
in this range can help remove mud in your sound.
500Hz – 4kHz: This broad slice of the sonic spectrum is where most
of your acoustic signal lives. Boosting here will make your guitar
sound more aggressive, while cutting will help mellow it out.
4kHz – 8kHz: The brightness of your acoustic lives in this region. If
your instrument sounds like you’re hearing it through a wall, boost
in this range. Cutting in this range will remove harshness.
5kHz and Above: Boosting in this range will bring out air in your
sound, and cutting will reduce noise. Beware of feedback though!
