Thanks Tetness - you may just have sealed it for me.
33609 feelings are kind of weird. You see people raving about them, and then others going off them, saying they can't get them to work on the 2-bus and moving onto something else, and then more recently people raving again about the JD! I've only used the J, which I really liked, but I felt it was taking a little top off the mix. It does have that sound though - perhaps the JD has made the difference.
Time to dust the cobwebs off my plastic ......
