Yes, it was my idea. I thought tort binding would blend really nicely with jazzburst, but I wanted both the top and side with a multi-ply to make it pop a bit.
I explained it to BCR Greg, and he knew exactly what we needed. I had never heard of "stacked purfling" before, but I had seen acoustics with it before.
Greg worked some magic with the shop to get this done. The anniversary inlays were a tough sell, and note that the f-hole has the binding stacked as well. I still have no idea how they did that.
