Quick questions for the profession builders out there.
In regards to soundhole size/rosette diameter ratio, is there a golden rule for certain sized guitars, or is it purely eye of the beholder kind of stuff? Does a sound hole have to be a certain size?
Secondly, depending on the fretboard timber I select, I may include a 12th fret marker, and as mentioned before, I have been thinking of doing rectangular block made up of scrap pieces in this style
So, the question is, can this block inlay go full width without affecting the integrity of the fretboard, and also double up as the side marker for the 12th fret? What issues would this raise, if any?
Due to the time frame of the course, fretboard binding is not an option.
