I don't believe that Washburn has produced any swamp ash N4s to the new Davies/reissue spec (aka 2.0). It may be in the works, but something tells me that if it happens, it'll be a very limited run. I'd suggest that your best bet in getting one is to contact Jon at Funky Munky music and have one commissioned. You may end up having the only Swamp Ash N4 2.0 out there....for now, anyway. Seriously....contact them.
