Good question. I don't actually know. My C is number 40 from the first batch. I guess I would need to take the pickguard off to check? Last time I had the pickguard off, Jim Campilongo was playing in town. I thought it would be cool to have him sign the pickguard, but I did not want to haul the entire guitar to the concert. So I carefully unscrewed the pickguard, lifted it off...and discovered that was already signed by Jim on inside. So I put it back. I only found out later that there were different pickups used in the C's. Whatever they are, they are absolutely friggin' gold.
