You got a point there. Something soft would be nice. Some guitars are modeled on a cloth. But a strap means unrealism to me. Everytime I would render a different angle, I would need to move the strap in a different spot. Now as far as pickups go, you must have been mistaken. These pickups are EMGs (humbucking) they are attached to a plastic piece and I'm sure It has a thin plastic cover. No metal pieces are involved except the screws. You are thinking of other ones.

You must be thinking of these: https://cachepe.zzounds.com/media/qua...4c36284fb0.jpg

That said, I will think of something soft to add.
