  • Parlor Guitars
    Smallest acoustic guitar body size. Preferred for fingerpicking. The have a light, yet balanced sound.

  • Concert, or Model “O”
    “O” guitars are slightly larger in size and like parlor guitars, are balanced in tone and response and produces deep bass tones. Suited for fingerpicking.

  • Grand Concert, or Model “OO”
    The Grand Concert is based on the shape of the classical guitar, and is one of the quietest acoustic guitars. Its sound is not as bright or balanced as the smaller models, and not as bassy or boomy as the larger sizes. It has a solid mid-range register.

    Like classical guitars, these produce clean, warmer sound. These are not harsh when played on the higher frequencies, but can produce a muddy sound when used for fast strumming.

  • Orchestra Model, Grand Auditorium, or Model “OM” or “GA”
    This model is also sometimes called an Auditorium or “OOO”. It is a mid-size guitar, with great balance, volume, and projection. It has more presence than the smaller guitars mentioned above but lacks the heavy bass response of the larger guitars mentioned below. Use it for finger-style playing, or for solo gigs.

  • Dreadnought
    This is the most common acoustic guitar shape. When people talk about guitars in western music, they usually mean this model. The dreadnought is a large-bodied guitar that has a lot of bass response. This guitar is a favorite among flat-pickers and is also great for accompanying vocals because of its full-sounding lower registers (support the voice well).

  • Jumbo and Super-Jumbo
    Among the largest guitars you will find, often used for strumming because of their great bass response. Popular in country music.
