Ovation acoustic guitars are different from the standard acoustic guitars in that the bottom and sides are combined in one bowl shaped structure, much like the lute. Specifically the shape of the composite bowl is semi-parabolic. The peculiar shape of the Ovation acoustic guitar contributes greatly to the durability and ruggedness of the guitar. The shape was designed by aeronautical engineer, Charles Kaman who applied his knowledge of aerodynamics to improve the flow of sound in the bowl.
The bowl comes in 4 variations:
- The Super Shallow bowl acoustic guitar is a very thin structure which gives off a distinct acoustic sound. Because of the shape, the bowl makes the guitar easy to handle and easier to manipulate while playing. When plugged in, the super shallow can produce an adequate sound for any playing venue.
- The Mid-Depth bowl acoustic guitar is slightly deeper than the Super Shallow and therefore can project deeper tones. The smaller size fits more players than do the other sizes.
- The Deep bowl acoustic guitar has the full range of acoustic sound and a deep tone for bass notes. The sound produced by the bigger sizes is favored by creative acoustic artists for the sonorous bass tones.
- The Contour bowl acoustic guitar is capable of the widest acoustic effects combined with the convenience of a smaller body.
The soundboards of Ovation acoustic guitars are carefully chosen from fine wood which can produce the vibratory effect that is the hallmark of Ovation guitars:
- Spruce produces an equality of tone, fullness and power that is characteristic of Ovation acoustic guitars. Spruce is particularly appropriate for solid mid-range and shimmering high-range tones. In choosing the wood for their sound boards, Ovation takes into consideration the consistency of color and the tightness of the grain. Wood with a firmly packed grain produces better resonance.
- Bearclaw spruce has the characteristics of ordinary spruce. However the grain pattern shows what looks like a bear's claws. The aesthetic appeal of this peculiar grain pattern gives the guitar a distinctive look.
- Cedar wood guitars produce sound that is richer for the lower tones while still retaining an overall balance of resonance.
- Figured koa is wood that is of Hawaiian origin. The wood itself is infiltrated with complex patterns and many color variations which makes a figured koa guitar visually interesting. High resonance characterizes this wood, particularly for the higher tones.
- Quilted maple tops are sure to capture the attention of your audience. They are the choice of musicians who want to be seen as well as heard.
Besides the conventional center sound holes, Ovation guitars come with multiple circular perforations called epaulets. Usually one epaulet is placed on the bass side of the strings and another on the treble side. However, guitars with bass epaulets are appropriate for bass guitars.
Ovation acoustic guitars are used quite often in recording studios in which the refinement of tones characteristic of Ovation acoustic guitars, allows the producers to choose a different type of guitar to produce a different musical effect.
