Not the color so much but the model is fairly rare, they were only made for two years from 1987-1988, and likely in lower numbers than the Standard and SG-62 (which the Elite is based on). That said, there was no strict production limit.
The color is actually called "Metallic Sunset". Yours is in great shape; most have faded to a more orangey shade by now. More info on the Elite here:
With active electronics or pickups on a guitar or bass, there is usually a preamp involved, whether it is built-in to the pickup or separate in the control cavity. The preamp is what requires the power source, being the battery. Pots and caps are passive electronic components.
