The D-Roc Standard pickguard has always been a little controversial. Its inspiration came from Mopar Challengers/Cudas from the early 70s. Matte black stripes on cool colors. One version of the stripes had a strobe graphic element that made them cooler looking to me than the typical racing stripe. The "strobe" graphic on the D-Roc pickguard references a wing but also the stripes on a Mopar muscle car.
The cheapest solution on a curved surface like the D-Roc would be no pickguard. Heat forming flat plastic to conform to the curved surface of the D-Roc would be cost prohibitive and prone to manufacturing errors.
The vinyl design must be done very carefully. Factoring in time and labor, the vinyl D-Roc pickguard costs as much or more than a typical 2D pickguard. For those who don't care for the aesthetic, it's easily removeable.
