60 hz & 50 hz hum

Recommended Posts

Yes but for some reason I didnt expect to hear a noticable difference.

Actually, I do know why. It's ignorance.


I read a book on acoustics (the science, not the guitars) from the 'Teach Yourself' range when I was at college. I never understood the physics but I got the principles ok.


What interested me was the note collision you get when two sustained notes of slightly difference pitch happens. So 300 hz hits 308 hz and you hear/feel the 8 hz difference as oscillation. Yes, I should've been chasing girls.


You can hear it here from 16.04 to 16.16

The oscillation; not girl chasing.

Its on Garcia's guitar.
