Here are 2 2016 D-28 guitars back to back, without being re-strung. There is a high probability that one set of strings is slightly older than the other.
Here are the same 2 guitars, recorded immediately after being strung with brand new sets of Martin MSP7200 strings.
In both cases, the audio was recorded with a Rode NTG-2 direct to disk with no processing, effects or EQ. Same guitars, same room, same pick, same playing style. What are
you hearing?
