I've always liked archtops but came to them from having them mistakenly show up in "parlor guitar" eBay searches years ago. I was drawn to the smaller ones so when I did see his Olympic, I thought it hit things right. I'd always liked the sound of their two guitars together, occupying different sonic space.
I was able to jump on a 1934 Olympic recently and Dave Rawlings is definitely the reason I bought it. Simply enough, I probably wouldn't have known about that model without him.
I've only played it with others once so far and it performed as expected. It was a fairly large bluegrass jam and I didn't have to work as hard to pick those lead lines. They cut through the mix better.
