Tuning Analysis: BFBDFA Low B

The 'BFBDFA Low B' tuning, created out of necessity by its author, offers a distinct and powerful sonic landscape. Originating from a situation requiring a replacement for string 1 with a heavier gauge, this tuning transforms a standard guitar into a formidable instrument particularly suited for heavier musical styles. The creator noted its appeal for "heavier stuff" and its synergy with reverb and other effects, suggesting a sound that can be both massive and atmospheric.

Technical Observations

This open tuning comprises the notes B1-F#3-B2-D#4-F#4-A#4 (from low E to high E string positions). When strummed open, these notes form a rich and resonant B Major 7 chord (B, D#, F#, A#). The inclusion of B at the 6th and 4th string positions, along with F# on the 5th and 2nd, provides a deep and full voicing of this chord across the instrument's range.

• The extremely low B1 on the 6th string provides a deep, guttural foundation, ideal for crushing riffs and heavy power chords, underpinning the 'heavier stuff' mentioned by the creator.
• The arrangement of the lower strings (B1, F#3, B2) makes for easily accessible power chords and octave shapes, lending itself well to riff-based music.
• The open B Major 7 chord (B, D#, F#, A#) itself offers a sophisticated, full, and somewhat melancholic or ethereal quality, which can be used to create expansive soundscapes when paired with effects like reverb, or to add harmonic complexity to heavy passages.
• The tuning's design, with several strings tuned down significantly (ranging from 3 to 6 semitones), aligns perfectly with the creator's choice of heavier string gauges like Ernie Ball Skinny Top Heavy Bottoms and a .013 gauge for string 1. Tuning down by 4 or more semitones often necessitates a heavier string to maintain proper tension and intonation, preventing floppiness and ensuring clarity, which has been thoughtfully addressed in this tuning's conception.

This tuning offers a unique blend of heavy low-end power and sophisticated harmonic potential, making it versatile for both aggressive riffing and atmospheric sound design.

How to Tune (from Standard EADGBe)

To achieve the 'BFBDFA Low B' tuning, follow these precise string adjustments from standard EADGBe tuning. Please note the recommendations for heavier gauge strings when tuning down by 4 or more semitones to ensure optimal tension and tone.

• String 6 (Low E): Tune down 5 semitones to B1. (Heavier gauge string advised)
• String 5 (A): Tune down 3 semitones to F#2.
• String 4 (D): Tune down 3 semitones to B2.
• String 3 (G): Tune down 4 semitones to D#3. (Heavier gauge string advised)
• String 2 (B): Tune down 5 semitones to F#3. (Heavier gauge string advised)
• String 1 (High E): Tune down 6 semitones to A#3. (Heavier gauge string advised, creator used a 013 gauge)
