Location: Scotland | The shape of the soundhole is pretty much an aesthetic consideration, on oval hole or round hole, or for that matter a cluster of holes wont make much of a difference tonally as long as the size is a constant. Placement is another issue, moving the hole/holes away from the centre of the top allows for a greater area of soundboard to vibrate. The Shape of the box can be another variable, in that boxes with parallel surfaces (eg dreadnoughts) can promote standing waves whose frequencies are related directly to the box dimensions. The lack of parallel surfaces in an Ovation bowl will distribute the standing waves more evenly. I've often thought that this could be one of the factors that contributes to Ovations signature sound. |

Location: Lake Hiawatha, New Jersey | Interesting to me...last year prior to the new MEII1598 coming out (which is the newer version of the Melissa Etheridge 12 string Adamas with one set of soundholes) I saw Melissa's ME1598 (original ruby version) very close up. The soundholes on the treble (string) side were plugged in with wood painted flat black to seal 'em up, in order to sound closer to the newer model...and still not be so obvious. Apparantly she was not 'ready' yet to play the new one publicly, so she modded the old one for performances in the meantime.
Anyway...

| On several upmarket guitars (and I do mean UPmarket - John Montleone and several classical makers) they offer a port in the side - top shoulder - so that the player hears what the audience hears. It doesn't appear to affect the front projection at all, although nobody's ever let me play one to find out. |

My guess would be that they'd sound pretty similar, all things being equal, which they rarely are. |

Location: Capital District, NY, USA Minor Outlying Islands | So the removal of the lower bout soundholes increases the base response while decreasing the treble response. From the above, I get the vibe that most people want to give up some high end for more bass. I'm stickin' to my preferences though, holes on both sides for pure acoustic playing and holes on one side for amplified.
PS: Thanks for the explanation PT |

Now I'm not so sure.
Have you ever considered politics? :D |

Location: Warren,Pa. | Paul, Sometime I wouldn't mind reading a post with a more thorough explanation of the Helmholtz frequency. I know I'll get comments about being a geek, but I'll also bet I'm not the only one who wants to hear more. Maybe a link to save you some time...but then it's fun to hear it in YOUR words. Tks, John <>{ P.S.- Thanks for being so kind to Lisa on the tour. That was her first time rubbing elbows with the BIG guys and she's got enough inspiration to move her playing 10 levels higher. |

If you do a search in the archives for "Helmholtz"
(narrowing the search down by searching only Master Templeman's post - by entering his Member #), you'll find a quite nifty, descriptive post that he did a couple years ago (if I remember correctly) . . . . . |

they explain some of the acoustic physics of guitars in relatively simple terms |
