I don't know if they "phased them out", but they may have stopped buying them around then. I was able to buy them until sometime last year, but I think they were NOS. The glue was getting a little iffy and it was nearly impossible to get the "Made in USA" part of the label to stick. Seems to me somebody there said back then that they had to buy them in pretty large quantities (like 5000 at a crack), so it wasn't something that they replenished on a regular basis.
They do need to come up with something nice soon, though. Nobody likes a blank headstock, and stickers/decals look tacky over a finished part. Who wants to pay $300 to $700 for a neck and put a sticker on it?
