Re: mass produced instruments & size variations
My personal experience has demonstrated to me that differences in standard mandolins to have small variances. Small differences in scale length & width, with the most significant difference in neck profile.
Mandolas, however, I have found all over the board.
Stiver A style (MAS has stopped here)
Kentucky KM-950
Keith Edward Coleman A style, oval hole Mandola
Weber Gallatin A Mandola "D hole"
Rogue 100A (current campfire tool)
Harley Benton A style (grandchildren's learner)
