I am an archtop builder and made a carved Mahogany/Sitka 15” model a couple of years ago. Floating Kent Armstrong pickup. Top was made from 20 year old billets from the Bellanca Aircraft wing factory which used to be in my home town.
It has a very warm acoustic sound and is very easy to play ergonomically compared to a 17” model.
Big drawback? The carved Mahogany body feeds back a lot more than Maple or a laminate back. For me F hole plugs are mandatory even on a fairly quite stage.
I still love the guitar.
