Ummm...I kinda thought that's what "creds" were...but if we've got different semantic interpretations of the term, so be it.
Anyway, like Frono, I put a whole lot more credibility in your observation after learning about your background, didn't mean anything snarky by it.
If it came off that way my apologies.
I never really doubted you heard it.
No problem.
About the cred thing, I wanted lots of opinions.
But when a person withholds theirs and defers to the opinion of another person we lose a vote, one data point.
Everyone has ears and can answer the simple question for themselves.
If the answer is they don't hear it, just say so.
That's a legit response.
That can bring up a discussion of why some don't hear it, while others do.
After all these posts I do believe one reason many don't hear the extra bass on those two notes is they are listening on their phone or other device that can't produce bass way down at 130 Hz.
I listen on my home computer connected to $2,300 of high end audio gear including a parametric equalizer adjusted to eliminate the worse resonances of my room at my listening position.
IOW, my gear gives me a wide and nearly flat frequency response ...
FAR from the usual way people listen to music.
Yes the source is low-fidelity - Youtube.
But we're listening for
a dramatic bass difference of two notes in a scale, not for whether all of the bass is rolled off.
... I guess you were just looking for confirmation that others could hear what you hear?
Yes.
That, and what the source of the resonance might be.
As someone has written, I suspect it is the resonant frequency of the body of that guitar and/or guitar size.
Again, I do intend to get out and try some M 20s.
Thanks all.
