F♯ 7th suspended 4th is built from the formula 1, 4, 5, ♭7. The perfect 4th between F♯ and B creates the suspended sound, while the minor 7th E adds tension. Compare it to F♯ suspended 4th, which omits the minor 7th.
F♯ 7th suspended 4th acts as the V chord in B major, appearing in the I–IV–V–I progression B major–E major–F♯ major–B major. It suits rock and blues bass lines that need a suspended dominant. Compare it to F♯ minor to hear the difference between a suspended dominant and a minor chord.
The 2nd-fret shape keeps F♯ in the bass for a root-position sound. The F♯7sus4/C♯ inversion at the 9th fret puts C♯ in the bass, which softens the chord and works well for a lighter texture.
