Re: What planet is he on!!
Back in the early 90s there were a number of stores in the UK from which you could order JEMs with different necks. FCN, the then UK distributer freely sold JEM necks to certain stores and you'd often see them listed for sale in the magazines of the time.
And to answer the Euphor's question... I've seen one other DY with a PBK neck, it belonged to a chap who did quite well in a Guitarist Magazine "Guitarist of the year" competition in about 92.
Granted I think this guy is making more of things that the guitar warrants, but it's not as misleading a description as folks might think.
