I doubt if this is factory, but I have been known to be wrong!
We did use the Egnater cloth on the front, then cleared over it to make a solid surface, glued white binding around the perimeter, the Sin did a great job matching the standard tan stripe on the amps and put one on the back of the guitar, then we sealed it in a fine textured clear to resemble the finish on the amps. It was a fun project to work on and I'm glad the guys at Egnater were happy with it.
Thanks guys. After the cloth was glued down and clear put over it, we did rout the binding channel in a more traditional way that left a ledge so the binding could be glued in place. It has a combination of Axis and Super Sport electronics mounted to a custom control plate and Egnater supplied the cloth, knobs, and logos.
