(And they aren't coming from China). That might be where some of the

I agree, I've done the same with CIJ's, etc. These are very inexpensive mods to do that quickly enhances your guitar's stability. I did the same with the CV50 immediately along with a pup change (which was planned before I bought it).
As Mark says, I think there was a bad batch of pups or something funky going on here with the CVC's. I literally tried the pups in my CV50 for 5 minutes to be sure they worked before having the mods done to it, but I also don't recall people mentioning this issue at all with the initial run of CV50's... in fact, many were pleasantly surprised by the stock pups.
