Thanks and yes, this is 100% a riff on the Combo 600 shape, hence the name.
I'm going through a hardware update so I plan to use renderings to show my current offerings with the updated hardware spec. Bridges will be Hipshot B-style and the updated ring shapes are below. The control plate will be the traditional T-style hot-dog shape, but with three holes vs. two plus a blade and the holes are drilled to allow a switch to be mounted in the center or at one end.
I'm very happy to hear that people like the design...one never knows with these things.
