Welcome to the Deep F Power Drop tuning! This is a unique and extremely low tuning designed for heavy, resonant tones, taking your guitar into impressively low registers.

Verbal Analysis

This tuning is characterized by its exceptionally deep F2 notes on the two lowest strings. The lowest F2 is an almost subterranean pitch for a guitar, sitting just a half-step above a standard bass guitar's lowest E string. This creates a massive, resonant foundation for your sound, making it ideal for genres requiring immense weight and intensity.

The unison F2 strings provide an unparalleled thickness and a rich, droning quality that can be incredibly impactful. The tuning then progresses with a series of drops, forming a unique sonic landscape that feels both familiar due to its underlying D Standard influence, yet profoundly altered by the extreme low end. Given the extreme low tuning, especially on the lower strings, a heavier gauge string set is highly recommended to maintain proper tension and intonation, though the original tuner mentioned successfully using a .11-.56 set by playing softly.

Technical Analysis

The open strings for the Deep F Power Drop tuning are F2, F2, C3, F3, A3, D4 (from the lowest to highest string).

• String 6 (Low E equivalent): F2
• String 5 (A equivalent): F2
• String 4 (D equivalent): C3
• String 3 (G equivalent): F3
• String 2 (B equivalent): A3
• String 1 (High E equivalent): D4

Analyzing the intervals between open strings:

• String 6 to String 5 (F2 to F2): Unison. This provides a very thick and foundational root.
• String 5 to String 4 (F2 to C3): Perfect 4th (7 semitones).
• String 4 to String 3 (C3 to F3): Perfect 4th (7 semitones).
• String 3 to String 2 (F3 to A3): Major 3rd (4 semitones).
• String 2 to String 1 (A3 to D4): Perfect 4th (7 semitones).

The open strings F2-F2-C3-F3-A3-D4 collectively contain an F major triad (F, A, C) with an added D note, making it an Fadd6 chord. This offers rich, open voicings. The immediate power and commonality lie in the lower strings:

• Open Power Chords: The two lowest F strings (F2, F2) combined with the C3 on String 4 (F-F-C) create an immensely powerful F5 chord. This structure makes power chords across the lower strings very easy, often requiring just a single finger barre across the desired fret on strings 6, 5, and 4 to form new root-fifth-octave shapes.
• F Major Shapes: The F3 on String 3 and A3 on String 2, along with the F2 and C3, contribute to an F major tonality, making it relatively straightforward to voice F major and related chords.
• D Major/Minor Shapes: The presence of D4 on the highest string, and A3 on the second highest string (A-D perfect fourth), means that D-based chords might also be within reach with careful fingering.

This tuning is exceptionally well-suited for heavy riffs, drone-based music, and any style where a deeply resonant and powerful low end is paramount.

Tuning Notes

• String 6 (Low E equivalent): F2
• String 5 (A equivalent): F2
• String 4 (D equivalent): C3
• String 3 (G equivalent): F3
• String 2 (B equivalent): A3
• String 1 (High E equivalent): D4

How to Tune Your Guitar to Deep F Power Drop

To achieve the Deep F Power Drop tuning, you will be adjusting your strings from standard EADGBe tuning. Please proceed with caution, especially with significant pitch changes. For optimal performance and to prevent string breakage or damage to your guitar, consider a heavier string gauge for the lower strings, particularly if you plan to keep your guitar in this deep tuning.

• String 6 (Low E): Tune up from E2 to F2. This is a movement of 1 semitone up.
• String 5 (A): Tune down from A2 to F2. This is a movement of 4 semitones down. *Caution: Tuning down 4 semitones is a significant drop and may require a heavier gauge string for optimal tension and sound.
• String 4 (D): Tune down from D3 to C3. This is a movement of 2 semitones down.
• String 3 (G): Tune down from G3 to F3. This is a movement of 2 semitones down.
• String 2 (B): Tune down from B3 to A3. This is a movement of 2 semitones down.
• String 1 (High E): Tune down from E4 to D4. This is a movement of 2 semitones down.

For any tuning exceeding a negative 4 or positive 4 semitone adjustment, using a different gauge string is generally advised to maintain proper string tension and intonation. The original description suggests a .11-.56 medium top heavy bottom set can work, but for a permanent setup, consider custom gauges for the lowest strings to ensure stability and tone.
