The Physics of the Guitar Fretboard

For modern guitarists and producers, matching your EQ to the physical notes of the instrument is a game-changer. Standard guitar tuning (E-A-D-G-B-E) covers a wide frequency range, from the deep 82 Hz of the low E string to the piercing clarity of the 24th fret on the high E string.

Essential Frequencies for Mixing

• 82 Hz (Low E): The fundamental root of the guitar. Be careful not to let this clash with your kick drum or bass synth.
• 196 Hz (Open G): Often where the "body" of the acoustic guitar resonates. A light dip here can reduce muddiness.
• 1.3 kHz (12th Fret High E): This area provides the definition for solos and lead lines.

The Octave Rule

Remember that the 12th fret is exactly half the length of the open string, which means the frequency is exactly double the open note. This doubling is how an octave is physically defined in music.
