My original guitar design was based off of two parabolic curves like a satellite dish. The goal was elimination of sharp corners that could cause standing wave cancellation that negatively impacts the tone of the guitar. I had people for years saying: "The back is round and so am I, why can't you make it fit my body better. I didn't think it was that big of an issue, but finally made a couple of prototypes and, yes, it does fit better if you are not as skinny as you used to be.
I don't have a name for the new back, I have my original, which could be called the classic and the new one, which I'm just referring to as the alternative back. It's not really a new model, it's available on every acoustic guitar I make. So whether you want the Canis Major, Canis Minor, Double cutaway or Hollow body electrics, you can get it at no extra cost like most of my options. I'm hoping to get a review or two done later this year and when I do, will get them posted on the site.

Yes, I do business a little different than most companies. You think that's unusual, here's another one:
Left hand guitars available for no extra cost.
