....they are put there by a few ovation player who have partaken in the past, or continue to partake now, in mind altering chemicle substances. These substances have been known to cause "flashbacks" years after the fact. IN this case, one of the effects of the flashback is that the multihole layout causes a chemical release in the brain that makes the person believe that the holes are all getting smaller and eating the sound of the instrument in question, or that the holes are allowing all of the sound to leak out at once. The solution is the installation of "RETAINERS" to keep the guitar from eating it's own sound, and to keep all of the sound from leaking out at one time. Think of wiring an overweight persons jaw closed. Same principal in reverse...

Location: N.J. | They are about $15 and I use them on my Adamas one twelve string.Why more people dont use these is beyond me .The bottom really comes alive with these and just seems to bring out a "fullness" that cant be achieved without 'em. I've found that only putting them in the upper side has the best results but of course,ymmv.Best money ever spent for under $20!!! Al usually keeps 'em in stock too.HIGHLY RECOMMENDED!! :cool: :) |

Location: CT | If you have a deep bowl and you need to kill feedback, it's a no brainer. Much cheeper than the pedals and rack gear, and you don't need to have a degree in acoustics. I haven't needed it on the shallow bowl, and haven't tried it on the mid depth 12 string yet. IMO it kind of kills the low end. All of you acoustical engineers correct me if I'm getting this wrong, but as soon as you plug the hole, it is no longer reflecting sound waves (though it does resonate somewhat), and what you have left is the piezo pickup on the soundboard creating your sound, taking much of the bowl size out of the picture. Sort of makes the deep bowls sound like the shallow ones. Of course, there is always the guy at the board with his hand on the eq knob. |

All of you acoustical engineers correct me if I'm getting this wrong, but as soon as you plug the hole, it is no longer reflecting sound waves OK, here's the correction, as requested. You'e are right that it kills the low end, but it's got nothing to do with reflecting sound waves. A sound hole is merely a port which helps define the guitars helmholz frequency. The size of the sound hole is related directly to the volume of air in the body and there is an optimum size which will produce a balanced sound. Change the size of the hole(s) and you alter the guitars response. Slighly smaller soundholes produce a little more bass given the same air volume (Interesting to note here that many people seem to like the sound of single epaulet Ovations) Bigger sound holes (take the door off an Elite or Adamas) or no soundholes (close the holes with rubber bungs) and you raise the resonant frequency of the guitar, lowering the bass response.
As a means of feedback control the Airlocks work pretty well and are better than nothing, but they only work at moderate volume levels. If you are cometeing with a rhythm section and/or like your stage monitors loud you'll need a second line of defence. |
