The fireglo shade and pattern (darker area is thicker near the tailpiece) suggests a very recent 330, but that DOES look like a pre-1985 headstock. '70s?
I've done the toaster conversion on my '84 330 with VERY happy results, but I've been on the fence about adding the black knobs. I think I may do it now!
How 'bout a photo of your MODded guitar, showing it from the front?
