MSG-3: GUITAR Stamp - The MSG-3 stamps a precise, 5-fret guitar fretboard which is perfect for chords, scales, and arpeggios. The stamp pattern is half the size of the pattern stamped by the MSG-1. Just right for example, adding guitar chords in-between staffs on manuscript paper for chord/melody arrangements or where a smaller fretboard imprint works better. 5" x 5"
