i have a jem 03 and a pgm 05
there are a lot of differences in the necks. the pgm has 18 to 20mm neck and the jem has 19 to 21. if you have your hands 5 hours a day on a pgm neck and you grab a jem you'l notice, but thats not a problem, both necks rule! also the pgm neck has a more flat front site and bigger frets i think. and also the finish on the back of the pgm neck is thinner so it gives a nice slide on the hand.
pgm necks 04 or 05 are both awesome. and personaly i like more the 05 neck because it's stronger.... and i want this neck to last
