JohnInKansas, I have a question. What is the difference in sound between an A and an F model? I've played both and can't seem to see much difference in sound between two similar mandolins. I've played an F style Eastman and an A style and really found the shape to be the major difference. They sounded similar and I couldn't see spending hundreds of dollars for a fancy strap peg, so I bought the 605 A style. I played at a few Bluegrass festivals where I had the only A mandolin, but I love the sound. I was forced to borrow an Epiphone F model once when mine was in the shop and it was a disappointment.
I can't see how adding a scroll to a mandolin would improve the tone at all, but it sure ups the price.
