As I’m doing vintage guitar research at Vintage Instruments in Philadelphia, PA, I was able to do a little side-by-side comparison between my Dreadnought and some excellent examples of pre-war Gibson Jumbos.
Look forward to more photos from this amazing field trip!

Nice! How fortunate to see all of this. The Miller looks great along side the Gibsons.
Thanks!
