Thanks Chris, yes in that article I read it was explained that F# is the ideal ARF. How can one measure the ARF after the guitar is built, maybe at home?Chris Sobel wrote: ↑Sat Apr 13, 2019 11:55 pmThe air resonance is one of many frequencies on the guitar so it is difficult to just consider it by itself. I’ve noticed a trend in guitar sellers using this information and making a lot of claims about the sound just based on this one element.
As a general idea, older guitars tended to have lower resonances than modern guitars, although many modern guitars are made with air resonances around F# or lower. I feel it gives the guitar a darker, more ‘old world’ sound rather than a brighter and more trebles-forward sound that you might get with air and top resonances around G#.
I’ve made a number of guitars with lower resonances and once you start to go below F it becomes more of a challenge to build in great trebles. I now tend to keep mine from F# up to G# depending on what the client is desiring—it is a variable that I set and can control depending on a number of construction features.
Wow D! I didn't really enjoy the sound though. As Miles explained in the video and Chris here, it affects the trebles and that's the trouble. It would be interesting though, if a member of the forum who has guitars with different ARF could make a comparison video or audio.
Then Steve Connor guitars should have a very low ARF with those huge sound ports, right?astro64 wrote: ↑Sun Apr 14, 2019 3:04 amThe air resonance is not going to drop much with aging. To obtain a significant change in the frequency you could e.g. thin the top (something that could happen if you sand it down significantly in refinishing the instrument) or add sound ports. The reason the older guitars tend to have lower resonance is because they were built as very light instruments to begin with.
There isn't an "ideal" air resonance, and the air resonance is only one factor in the tone of a guitar, but it does give the guitar an overall character I think. In general, a lower air resonance will give the guitar deeper, warmer basses - but as Chris says, the trebles can become a bit more challenging. I don't think it's correct to say that a low resonance guitar will have weak trebles, but rather that they are likely to be less bright. I have played guitars with air resonances at D# and lower, and they can have very sweet, beautiful trebles, but some players like a really bright treble tone, and you're not likely to get that.
You are most welcome Dave. Antigoni Goni is a marvelous guitarist and she is absolutely right. Here I am a year into learning about my GC82S and only now do I feel that I can really begin to work with my instrument and all it has to offer. Interestingly, I find that a new car takes me about two years to really "groove" it.Dave M wrote: ↑Sun Apr 14, 2019 4:53 pmBeowolf thanks for reminding me of that clip. I just love the sounds that Ms Goni can conjure out of these instruments.
And the point she makes about having to learn how to work with a particular instrument seems absolutely right. Definitely something to bear in mind when one is trying out guitars, and indeed trying to evaluate one's own efforts.
