I know that's the list we've been using, but I think some additional basses got thrown in afterwards. For instance, there were make up instruments made when we went through the fiasco with the one (former) dealer. EBMM was very stand up about that whole situation. I don't know how many of those were made, but while that was going on I also heard that some artist instruments got added in after the fact as well.
I'm not sure we know the absolute final count, but I think it's more than 277, which is pretty much the number from the two ordering windows we had.
