You said YYS, so the lead time they gave you is because that's when production is scheduled for a batch of YYD's. A custom order would be in the order received. I believe necks are made minimum 6 months prior to any other work. 10 years ago it took 2 1/2 years for a YYD, but Superstorm Sandy was in the middle of that. Even if it took that long to get a YYD now, if I lost mine, I'd reorder in a heartbeat. The one bass I will never be without the for the rest of my life. YMMV.
