Hello everyone, just new here, so not sure how this works. I am very curious about the scale length on my F-30. Not knowing exactly what it is, it looks like it's a little over 24.5 inches but everything I read says the scale length is 25.5 inches. I would like to know if anyone knows if and when they changed scale??? Thanks for this. According to the serial # it was built early 1967 and it sounds absolutely great!
