I don't know what the USACG back contour is like, but if it is ANYTHING like my OLP MM-1 neck, I would say that you will LOVE it. Your results may vary, but it feels meaty AND slender at the same time. I know- very weird description.

I love my OLP neck so much that I am having a mahogany body built for that neck.

As I say- just say NO to basswood...
