    On an acoustic guitar, the bottom half of the soundboard does
    most of the moving. By using a cutaway, you have less cross-
    sectional area on the critical side of the soundboard, and probably
    less mass as well. The bracing also has to be differant to accomidate
    the shape. All things considered, the cut-away has to have some effect
    on the instruments' tone and volume. Many of the new cutaway acoustics 
    are Jumbo-sized which probably makes up for some of the lost cross-sec-
    tional area, and mass, resulting in a Jumbo sized body with the
    relative sound of a dreadnought. Of course all of these things are
    all theoretical differances, and guitar manufacturers/luthiers have
    all got their own approach to desinging guitars with cut-aways to
    retain the warmth, evenness, and volume of standard-shaped guitars.
    The true test is "your" ears which will ultamately decide whether
    or not you like an instruments' tone.
    
    When you start getting into acoustic/electrics, and how a guitar
    sounds amplified versus unamplified, it is a completely differant
    story. Ovations have long had the best sounding electrified acoustics,
    but their guitars do not have the volume and tone of a wooden
    instrument when played acoustically. They typically have the smallest
    bodies, but the biggest sound (when amplified) because of their
    pickup/preamp system which is far superior to anything else on the
    market.
