I just went to a lecture where the lecturer was explaining a way to measure the response of a accoustic guitar with an exciter on the bridge and a method called the exponential sine sweep method.
He was suggesting that you could measure and then replicate a guitars response onto another guitar and using this you could make far more accurate replicas. This could be used to preserve the sounds of old famous guitars.
My question to this community is would consider buying a guitar based on a graph of its frequency response and how that compared to other guitars? Is this valuable research?
For a buyer or player? Complete bs probably used to inflate prices.
For someone researching guitar manufacture? Potentially interesting.
I believe the concept was more for manufacture and preservation of old instruments.
