    Default Why do early Gibson A oval holes sound so mellow? Any research?

    Has anybody analysed why the early Gibson A oval holes sound so mellow, compared to F style F holed mandolins more dominant but also more thrill sound?
    Or is just a coincidence that some sound like that and others don't?

    If you read Dave Cohen's research work then you will get some clues. Basically the normal modes of vibration (i.e. how the thing vibrates) are at different frequencies. An F hole mandolin has the modes of vibration at higher frequencies. Why that is, is related to how the instruments are constructed, and the F hole vs Oval soundhole has a lot to do with it.

    One good reference to start with -

    Well, slightly heavy construction and a very shallow neck angle.

    Those are factors mainly affecting the power and response of the instrument. But what really makes ovalholes and f-holes sound and act like different families of instruments certainly is the difference in top geometry and ensuing difference in top and airchamber frequency (among other things). I used to own a modern ovalhole, with the longer neck and high bridge placement of, say, an F5; it was also about 10% lighter than my Collings MF5, and it was immedlately recognizable as an ovalhole (and superior to the F2's and F4's that I've tried).
