It uses GE forward-shifted scalloped X-bracing for strong low end and a dynamic response. This model suits professional-level flatpicking and strumming, and also works well for recording where you want clear, full-range projection.","ideal_for":"If you're looking at popular professional jumbo/acoustic dreadnought options, the D-28's dreadnought 14-fret body, 25.4 in scale length, ebony fretboard, and GE forward-shifted scalloped X-bracing make it a classic professional choice for powerful bass and articulate highs (like other top-tier Martin-style dreadnoughts)."}]}
