This unique Guitar tuning, named "Open Bsus2," is a signature tuning often associated with musician David Maxim Micic. It's described as being pitched 3 half-steps higher than a conventional Open Bsus2, giving it a bright and expansive character.

Technically, when strummed open, the tuning produces a clear Bsus2 chord, built from the notes B, C#, and F#. This specific voicing creates a rich harmonic foundation, ideal for progressive rock, metal, or ambient soundscapes. The open strings are arranged as B1-F#3-B2-F#4-B2-C#5, providing multiple octaves of B and F#, along with the characteristic C# for the suspended second. The repetition of B and F# at different octaves across the strings provides a powerful resonance and allows for complex melodic and rhythmic ideas to be played over a consistent harmonic base.

The layout of these notes offers convenient access to a variety of chord voicings and melodic patterns. The multiple B and F# notes make power chords and octaves easily accessible. Chords featuring the major second (C#) will naturally resonate, while other common chord shapes can be re-imagined by focusing on the root (B) and fifth (F#) intervals, allowing for unique inversions and extensions that might be challenging in standard tuning. The high C# on the first string adds a shimmering quality, particularly effective for arpeggios and lead lines.

Due to the significant down-tuning required for most strings, players might consider using heavier gauge strings to maintain tension and intonation, especially for the lowest strings and the B2 string which is tuned down a full octave.

This tuning is perfect for exploring dense, polyphonic textures and achieving a modern, expansive sound.

Open String Notes:

• String 6 (Low E): B1
• String 5 (A): F3#
• String 4 (D): B2
• String 3 (G): F4#
• String 2 (B): B2
• String 1 (High E): C5#

How to Tune:

To achieve the Open Bsus2 tuning, start from standard EADGBe tuning and adjust each string as follows:

• String 6 (Low E): Tune down 5 semitones to B1. (Note: Tuning down 5 semitones is a significant change; using a heavier gauge string is recommended for optimal performance and intonation.)
• String 5 (A): Tune down 3 semitones to F3#. (Note: Tuning down 3 semitones is a moderate change, but may slightly loosen string tension.)
• String 4 (D): Tune down 3 semitones to B2. (Note: Tuning down 3 semitones is a moderate change, but may slightly loosen string tension.)
• String 3 (G): Tune down 1 semitones to F4#.
• String 2 (B): Tune down 12 semitones to B2. (Warning: Tuning down a full octave (12 semitones) requires a significantly heavier gauge string to maintain playability and intonation. Using a standard gauge string for this drop will likely result in very loose tension and poor sound.)
• String 1 (High E): Tune down 3 semitones to C5#. (Note: Tuning down 3 semitones is a moderate change, but may slightly loosen string tension.)

General Recommendation: For tunings with significant changes (particularly those exceeding 4 semitones up or down, or in the case of a full octave drop), using a different string gauge is highly recommended to ensure proper tension, intonation, and string longevity. Always tune carefully and be mindful of your instrument's setup.
