The ESP Guitar Company

hey everyone!  So I just got a used Ex400 for $200. It’s got some pretty good dings but it’s a live guitar so no big deal.  My question is, is it real?  I’ve yet to see an Ex400 with a silver logo and black hardware. I know the knobs were changed but I don’t think all of the hardware was changed as well.  It seems right with the serial number printing but I can’t find anything on the R prefix.  Any help would be greatly appreciated!!!
