Verbal Analysis:

The "Double E Drop D" tuning for a 7-string guitar offers a unique blend, as its description aptly puts it, for when you can't decide between E standard and Drop D. It essentially provides the best of both worlds with a powerful low E drone and the versatility of Drop D. The lowest string (7th) is tuned to E2, creating a rich, resonant foundation and mirroring the high E string two octaves lower. The 6th string drops to D2, allowing for immediate access to heavy Drop D power chords. The remaining strings (5th through 1st) maintain a familiar A2-D3-G3-B3-E4 pattern, closely resembling the standard EADGBe tuning from the 5th string upwards. This hybrid approach caters to players looking for both extended low-end range and the ease of traditional chord shapes.

Technical Analysis:

• Overall Structure: E2-D2-A2-D3-G3-B3-E4. This tuning creates a distinctive sonic landscape with several open string harmonies.
• Root & Fifth Foundation: The combination of the 7th string (E2) and 6th string (D2) provides a strong low-end, offering both a deep E and the characteristic Drop D root.
• Open Chords & Voicings:
  • Drop D Power Chords: The D2 on string 6 and D3 on string 4 (octave D) make 6-string Drop D power chords effortlessly accessible. For instance, playing strings 6, 5, and 4 open (D2, A2, D3) yields a powerful D5 or Dsus2 sound.
  • G Major Triad: The upper three strings (G3, B3, E4) form an open G major triad in first inversion, providing a bright, familiar chord voicing.
  • Extended E Minor: Fret the 6th string at the 2nd fret (E2). Combined with the open 7th (E2), 5th (A2), 3rd (G3), and 1st (E4) strings, you can achieve rich E minor or Em7 voicings.
  • Octave Drones: The doubled E notes (E2 and E4) and D notes (D2 and D3) create natural octaves for resonant drone effects.
• Versatility: This tuning excels in genres requiring both heavy low-end riffs (Drop D) and more melodic or traditional chord progressions (facilitated by the E and A-D-G-B-E segments).

How to Tune:

To achieve the "Double E Drop D" tuning, follow these specific string adjustments:

• 7th String (Lowest E): Tune up 5 semitones to E2. ***Caution: Tuning up 5 semitones significantly increases string tension. Consider a lighter gauge string to prevent breakage and maintain playability.***
• 6th String (D): Tune down 2 semitones to D2.
• 5th String (A): Keep as is; no change (0 semitones) to A2.
• 4th String (D): Keep as is; no change (0 semitones) to D3.
• 3rd String (G): Keep as is; no change (0 semitones) to G3.
• 2nd String (B): Keep as is; no change (0 semitones) to B3.
• 1st String (Highest E): Keep as is; no change (0 semitones) to E4.

The tuning for your 7-string Guitar is as follows, from the lowest (7th) to the highest (1st) string:

• 7th String: E2
• 6th String: D2
• 5th String: A2
• 4th String: D3
• 3rd String: G3
• 2nd String: B3
• 1st String: E4
