Apparently, mine. I am a responsible person... whenever something goes wrong around here, I am responsible.

Captain;
You don't have a 30? I thought everyone had one by now. If you ask, I'll bet Kramster would at least show you his, might even play it for you. |

I think it depends on whether it’s a choice or if you were born that way...
I personally can’t imagine having more than one of the same guitar but I don’t own many to begin with. But since you already have two, what’s one more? |

I cannot promise another Carbon Fiber Gathering, or at least one within your time frame in Arizona. Alice just flew down there to visit mom at the New Year, and it is not clear when we will drive south again. I would expect the fourth week of March or maybe the first week of April. As time gets closer I will start a new thread to coordinate things. Hope it all works out with your schedule.
The easiest option is meeting at Kramster's house if he is willing, so he doesn't have to rent a semi-truck and move the entire warehouse of Emeralds and other brands. Last year I tried to arrange a venue from afar but that didn't work out too well. We will most likely bring along my X20, X20-12, and X30 and the Blackbird Lucky 13 assuming I still have it by then. It would also be nice to compare the classic X7 and new X7 if that works out. I could bring a pro grade sound meter and we could make our own loudness measurements. But that would be like homework for me (that is what I do for a living). |

Hi Earl. We will be there through March. I understand your timing, as well. If it works, that would be a bonus. Maybe if I buy Kramster lunch he would let me look at his X30... through the window.

Interesting quick and dirty test, and not something that I've heard done a lot, so I appreciated getting to see it.
Obviously, a db reading on a meter isn't the whole story of loudness, but there's essentially no difference on the meter save for the X30. If I was to have guessed ahead of the test, having no Emerald experience whatsoever, I'd have guessed the X20 would have been louder than the X7 on the meter.

Loudness is a complex issue. Most meters can read dBA or A-weighted decibels. The A-weighting noticeably rolls off the lows and some mids to make the reading better correspond with subjective loudness. I often use the example of a railroad locomotive at 80 dBA (50 feet) and a high-hat cymbal at 80 dBA (measured at 2 feet). One has a huge amount of low end and WAY more acoustic power, the other only high frequencies and less power. But two juries of listeners would describe each having similar overall loudness. It's not perfect, but is the best that the industry can do.
A sound meter set to read dBA will give similar readings for any size acoustic guitar, as we saw. The dBA levels were quite similar even though you could tell that each larger guitar had a fuller sound with more bass. Using dBC or the the C-weighting (without the A weighting corrections, or a more linear number) would show noticeably different levels for guitars with more bass. There is also the variability of each strum. If you watch carefully, the level bounced around quite a bit. I told you this was complicated! This Wikipedia page explains it in more detail, with pictures: https://en.wikipedia.org/wiki/Weighting_filter |

Loudness is a subjective, rather than objective measure -- it's a measure of our perception of loudness at different frequencies rather than an objective, external value like temperature or weight. A guitar with an upward-shifted frequency response will probably register as "louder" -- this graph shows the wavy line of loudness and how poorly it corresponds to real, measurable sound pressure level. So, if the X7 has a stronger harmonic frequency spectrum in the 3-4 KHz range, to which the human ear is most sensitive, it will sound louder than a overall-higher-dB guitar with a mellower harmonic response that isn't as active in that "notch" of maximum ear sensitivity.

If you have a phone and are curious how loud your guitars are . . .
