I m launching Fretboard Lab today and I d love practical feedback from guitarists, teachers, songwriters, or anyone who builds chord sheets.
The product is for a specific problem: a chord symbol alone is not enough. Cmaj7, Am7, Dm7b5, slash chords, and Roman numeral progressions can produce several technically correct shapes, but not all of them fit the hand, tuning, fret span, open strings, or the next chord.
Explore playable guitar chord voicings across tunings, positions, fret spans, open strings, and Roman-numeral progressions. Built for guitarists, teachers, and songwriters who need more than one static chord diagram.
