I was thinking about it, but to buy a President case I will have to place an order with the local dealers, and it can take months. They don't have them in stock.
Ordering from Thomann, in Germany, I will have a case within a few days. So I was also looking at this one that they have in stock (they don't have a President case) - Hagstrom Viking bass case. Inner dimensions are right.
