Location: Lafayette, Louisiana | Bill, can you tell me who came up with the design or pattern of the multi-hole Adamas/Elite models? Was there alot of testing done to come up with the eleven holes per side on these guitars? |

Not alot, I always heard that the volume of the holes was equal to the volume of a round hole. I never checked that out. I'm sure some of the engineering-oriented of us can answer if that's true or not. I suspect not since the cutaway Adamii with only one set sound just as good although tend to have more bass responce.
Paul T care to weigh in on the subject? Or anyone else? |

Location: Upper Left USA | Master Temp did indeed answer that question with great acuity some time back. I'd look it up but I'm too lazy.
Take in mind the sound from the early smaller holed Balladeer. There's a real formula somewhere.
The area of the Epaulets is equal to the area of the mono hole. A single bout epaulet adds b-b-b-boomyness I hear. Wait til December 15th :D |

Location: Scotland | I think the fact that the holes were positioned in the upper bouts away from the centre is more influential on the sound than thier size or quantity. While there are acoustic principles involved in the relationship between a guitar's soundhole size and air cavity volume it wouldn't surprise me if Mr McDonough designed the Adamas soundholes purely on aesthetic values first. |

Have all seen the Ovation Copy out there where the holes are the same but the "lauts" are a Parrot shape?
I prefer the Quail feathers. |

Location: 6 String Ranch | Paul, I think that was the main motivation, the looks. Chuck was an artist, not an engineer. Another important aspect I've always thought was that the holes were smallish and the top was connected between. This way while there were holes the top area the top would still move and vibrate as a top and not be hindered by a big hole in it. Also moving them out of the way was important to get the whole top to generate sound. |

Location: Las Cruces, NM | Have to throw in an auto engine theory or fact here. A bunch of small holes are better than a few big holes, e.g. four valves per cylinder, V8 vs 6 cyl, V-12 vs V-8, and the greatest but seldom seen V-16, I saw an old V-16 truck engine from an old log hauler in a trucking company scrap yard in El Paso, awesome to imagine that thing under your foot as you went through 10 gears or whatever. Saw a Renault 12 cylinder Formula One at the old Ontario, CA racetrack at the only formula one race I ever attended, it was a screamer among the V8s and won the race, can't remember the driver but I think he was British and he was good.
Many small holes is very good in autos, 72 of which are lusted after by Muslim suicide murderers, VERY bad in pedophiles. There might be some scientific validity in guitars.
