I consulted The Book, and I have some questions. The Monaco is described as a hollow-body, with mahogany sides and back, while the Superpro is described as having routed chambers in its mahogany body. It isn't bent sides and separate back, so is there a difference in the chambering from the Superpro? Perhaps due to the Bigsby instead of stop bar, or differences due to the spruce instead of maple top? Definitely a new one for my dreamlist! Sexy!
