This guy is a little old hat by now I know, but I had a WFC Soundwave head and weapons sitting in my fodder box, and then I saw a Perceptor at Marshalls for $7, so it seemed like it was meant to be. Tore off Perceptors head and added a ball joint for Soundwaves noggin. Other than that, no mods. Painted him up, and gave him some mud splatter in vehicle mode. I'm not sure how well it comes across in pictures, but in person, I think his robot mode is by far the best looking TF I've ever done. However, Soundwave just isn't complete without a minion, so I made a tiny little Laserbeak for him out of styrene. He doesn't transform, but his wings and his head are articulated. Note: I have had a hell of a time trying to get him back into vehicle mode since I first transformed him. That and how loose his backpack is are the only things I don't like about him.
