FDP Forum / FDP Unplugged - Acoustic Instruments / "Opening Up"?

Back in the old

I recently purchased a Yamaha LS16 (000-size) solid spruce top solid mahogany body guitar.

Received it from MF; opened the box, opened the case, removed the guitar from the sheath in which it was wrapped in the case, tuned it up and blech. Dead.

Let it sit for a week on the sofa; picked it up again today -- it's not the same instrument. Now loud and ringing. Yay.

What's the deal?

My guess is humidity. Wood with a higher moisture content has more internal damping and doesn't "ring" or resonate as well as drier wood. And solid woods are more affected by humidity change than laminated ones. If the moisture content dropped during that week after the guitar came out of its wrapper, that could account for a change.

It's just a guess, but I think a plausible one.

Yes, it probably dried out some. Humidity has a way of sucking the sound out of an acoustic.

Can't rule out your ears, too.

Jimmy could've just got out the shower, you just don't know. :-p

Nah, my ears can get fatigued just like my eyes at times.

As littleuch says, it could just be ear fatigue.

All I can say is I've used exactly the same guitar/ amp/ room/ volume combination many times. Most times it sounds good/ great. Occasionally it sounds lifeless. No other logical explanation I can think of. Of course acoustics are probably more sensitive to humidity than electrics as well.

Fluctuations in ambient temperature and barometric pressure can also cause minute changes in psych-acoustic perception.

I think mirror boy is right about temp, humidity and new guitars are still settling in to place for a bit after they are built.
I remember playing a Goodall one day for about 45 minutes in the acoustic room at my favorite store. It sounded good but not great. My sales guy was walking out to see another customer about something and just as he opened the door ,mid note the guitar just leaped in volume mid strum. I saw his eyes just pop open at this point and he asked" did you hear that?" I said Yeah ! Maybe I had popped a brace loose or something? We got a mirror and checked it out and found nothing wrong. It had evidently responded to my heavy strumming by settling in somehow. I did buy the guitar and to this day it has maintained the same volume and smoothness that it " acquired" that day. You can't beat it out of tune either so it's the most stable tuning guitar I own.
I've had other guitars change volume/tone over a period of months/years but never like this.
