I will soon be the proud owner of a Gilchrist Model 1.
I'll be receiving it in a Calton case, and have the choice of an A or F insert. I'm trying to decide which insert to get.
Christie Carter of Gruhn said:
"The F case insert has the point and an ever-so-slight ridge under the scroll area. The F case insert will accommodate both the A and the F mandolin but the A case insert will only work with the A style case."
So it certainly seems like either would work.
I'm leaning toward the F so that it would be more flexible, but thought I would seek the opinion of the knowledgable folks at the cafe.
