There are a number of important characteristics which I build into my guitars. Clarity and tonal responsiveness - each guitar must possess a clear and distinct voice but must also respond readily to the player's efforts to shape its tone. String separation is important; Accurate intonation - the scale is fully compensated so that the instrument plays in tune on all strings at all parts of the fretboard; Power - strong projection without sacrificing tonal quality; Sustain - to allow the playing of slow passages with ease; Ergonomics - a slim neck with the fretboard elevated above the soundboard to improve upper fret access; Structural integrity - avoidance of bridge rotation and soundboard deformation in the upper bout.
